[0015] Various embodiments of the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the present disclosure are shown. In fact, the present disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements.

[0016] Overview

[0017] The wireless audio transmitter of a wireless audio system may be configured to broadcast radio frequency signals to one or more wireless audio receivers. Conventionally, a one-to-one communication link is established between the wireless audio transmitter and one or more wireless audio receivers of a wireless audio system to transmit radio frequency signals. However, there may be interference or other signal audio attenuation conditions in the radio frequency environment of a wireless audio system. Therefore, it is desirable to reduce the interference effects on the wireless audio transmitter and / or one or more wireless audio receivers in a wireless audio system.

[0018] For traditional wireless audio systems, if a wireless audio receiver detects interference with a wireless communication channel, the wireless audio transmitter and the wireless audio receiver can simultaneously switch to different wireless communication channels associated with different carrier frequencies. However, for certain types of wireless audio systems, such as, for example, in-ear monitor (IEM) systems, there may be multiple wireless audio receivers tuned to a particular wireless communication channel. Additionally, one or more of these wireless audio receivers may experience interference while one or more other wireless audio receivers may be physically positioned such that they do not experience interference. Thus, it is not desirable to disrupt the audio continuity of one or more other wireless audio receivers associated with interference-free operation, such as, for example, by retuning the carrier frequencies of one or more other wireless audio receivers or by otherwise interrupting the audio continuity. For example, it is generally not desirable to simultaneously switch the wireless audio transmitter and multiple wireless audio receivers to different wireless communication channels associated with different carrier frequencies.

[0019] To address these and / or other technical problems associated with wireless audio systems, various embodiments disclosed herein provide interference avoidance using transmission redundancy of a wireless audio system. The wireless audio system can be an in-ear monitor audio system or another type of wireless audio system. With transmission redundancy of the wireless audio system, radio frequency signals can be transmitted via two or more carrier frequencies. For example, a wireless audio transmitter of the wireless audio system can transmit radio frequency signals via two or more wireless communication channels that are each configured at a unique carrier frequency. The radio frequency signals can be audio signals, such as, for example, a stereo audio mix or a mono audio mix. Thus, depending on the conditions of the radio frequency environment of the wireless audio system, each wireless audio receiver in the wireless audio system can independently tune to an optimal carrier frequency (e.g., an optimal wireless communication channel) to receive the radio frequency signals transmitted by the wireless audio transmitter. To facilitate transmission redundancy, the wireless audio receivers can be configured as wide-tuning receivers capable of tuning to two or more wireless communication channels.

[0020] By providing transmit redundancy in a wireless audio system, interference avoidance can be provided for one or more wireless audio receivers. Accordingly, the corresponding wireless audio receivers can mitigate interference without unduly disturbing other wireless audio receivers in the wireless audio system. Additionally, low-impact interference mitigation can thus be provided for one-to-many broadcast applications such as, for example, IEM systems. It should be understood that transmit redundancy can be provided additionally or alternatively to mitigate one or more other types of wireless audio system conditions in addition to interference. For example, each wireless audio receiver in a wireless audio system can be independently tuned to an optimal wireless communication channel based on one or more signal attenuation conditions associated with the wireless communication channel. In some instances, the wireless audio receiver can be independently tuned to the optimal wireless communication channel based on an informed decision related to the corresponding communication channel conditions of the optimal wireless communication channel and one or more other wireless communication channels. Accordingly, by providing transmit redundancy in a wireless audio system, the performance of one or more wireless audio receivers in the wireless audio can be improved.

[0021] Exemplary Wireless Audio System and Method

[0022] Figure 1 FIG. 1 shows a wireless audio system 100 configured to provide transmit redundancy in accordance with one or more embodiments of the present disclosure. The wireless audio system 100 can be, for example, a personal monitor system, a personal stereo monitor (PSM) system, an IEM system, an audio performance system, a music performance system, an audio production system, a music recording system, a conference audio system, or other types of audio systems. In some instances, the wireless audio system 100 is a wireless multi-channel audio system (WMAS). The wireless audio system 100 includes a wireless audio transmitter 102 and one or more wireless audio receivers 104a-n. The wireless audio transmitter 102 can be a wireless access point, a wireless monitor transmitter, a wireless rack-mounted transmitter, or another type of transmitter. The one or more wireless audio receivers 104a-n can be one or more portable receivers, one or more wireless monitor receivers, one or more in-ear control receivers, one or more beltpack receivers, one or more conference unit receivers, and / or one or more other types of receivers.

[0023] The wireless audio transmitter 102 can be configured to transmit radio frequency signals 110 via two or more wireless communication channels. For example, the wireless audio transmitter 102 can simultaneously transmit radio frequency signals 110 at two or more carrier frequencies via the antenna 106 of the wireless audio transmitter 102. Thus, the wireless audio transmitter 102 can transmit radio frequency signals 110 via a wireless communication channel associated with a first carrier frequency, and the wireless audio transmitter 102 can also redundantly transmit radio frequency signals 110 via one or more other wireless communication channels respectively associated with different carrier frequencies. The radio frequency signals 110 can be audio signals, such as, for example, a stereo mixed audio signal or a mono mixed audio signal of a specific radio frequency configured for wireless electromagnetic communication. Additionally, the radio frequency signals 110 can be transmitted at a specific carrier frequency according to a specific wireless communication channel. In some instances, the radio frequency signals 110 can be modulated according to a modulation scheme for WMAS.

[0024] In some instances, the radio frequency signals 110 include an audio payload. The audio payload can represent the audio waveform of an analog audio signal or a digital audio signal. The audio payload can be audio data modulated via the radio frequency signals 110 according to a specific frequency, amplitude, bandwidth, and / or modulation scheme associated with the wireless communication channel. In some instances, the audio payload can be configured as encoded information within the sideband portion of the radio frequency signals 110. In some instances, the radio frequency signals 110 transmitted via at least a first wireless communication channel and a second wireless communication channel can include corresponding audio payloads.

[0025] In some instances, the radio frequency signals 110 additionally include control information. One or more wireless audio receivers 104a to n can utilize the control information to manage access to the radio frequency signals 110 via a specific wireless communication channel. In some instances, the control information includes information such as, but not limited to: a wireless communication channel identifier for a specific wireless communication channel associated with the radio frequency signals 110, a modulation scheme identifier, control symbols, error detection codes, synchronization information, handshake information, channel access information, power control information, volume control information, gain control information, equalization information, carrier frequency information, and / or other control information. In some instances, the control information can be configured as encoded information within the sideband portion of the radio frequency signals 110.

[0026] In some instances, the radio frequency signals 110 transmitted via at least a first wireless communication channel and a second wireless communication channel can include control information based on the respective first wireless communication channel and second wireless communication channel. For example, the radio frequency signals 110 transmitted via the first wireless communication channel can include control information associated with the first wireless communication channel. Additionally, the radio frequency signals 110 transmitted via the second wireless communication channel can include control information associated with the second wireless communication channel.

[0027] Additionally, in an example, the radio frequency signal 110 may include data symbols in resource elements of resource blocks for corresponding subcarriers, where the corresponding subcarriers are at least associated with audio data for a stereo audio mix or a mono audio mix of a corresponding audio device, and the corresponding audio device is assigned to one or more audio channels mapped to the corresponding subcarriers. The data symbols (such as beacon symbols, modulation symbols, etc.) may define subframes of a wireless frame. A resource element may be defined as a fast Fourier transform or discrete Fourier transform sample of a frequency dimension of the radio frequency signal 110 and a subframe of a time dimension of the radio frequency signal 110. Subcarriers mapped to audio channels may be part of a resource block and are transmitted through a wireless frame structure including orthogonal subcarriers. Subcarriers assigned to audio channels for different audio devices may be grouped into a single wireless frame. One or more guard subcarriers may be left blank between adjacent wireless frames in the frequency dimension. In another example, the radio frequency signal 110 may be configured as a modulation signal associated with frequency modulation, linear narrowband modulation, non - linear narrowband modulation, or another type of modulation technique. However, it should be understood that in some examples, the radio frequency signal 110 may be configured in different ways to facilitate data transmission.

[0028] The wireless audio transmitter 102 may be configured for two - way audio, including uplink - direction audio data and downlink - direction audio data. The uplink and downlink - direction audio data may be transmitted in different subcarriers or within one or more of the same subcarriers. When the uplink and downlink audio data are transmitted through one or more of the same subcarriers, one or more resource elements of the one or more same subcarriers may be left blank between the uplink - direction resource elements and the downlink - direction resource elements to facilitate hardware changes, which is commonly referred to as turnaround time. One or more blank resource elements in one or more of the same subcarriers may be referred to as a guard period within the same wireless frame. A guard period may additionally or alternatively be provided between different wireless frames scheduled over a period of the time dimension of the radio frequency signal 110.

[0029] The antenna 106 may be configured as one or more antennas to facilitate simultaneous transmission of the radio frequency signal 110 via two or more wireless communication channels. By providing transmission redundancy for the radio frequency signal 110, interference and / or another type of undesired condition associated with the radio frequency signal 110 may be mitigated. Although Figure 1 the antenna 106 is depicted as a single illustration, it should be understood that the antenna 106 may be configured with two or more antennas (not shown) to achieve efficient transmission of the radio frequency signal 110. For example, in some examples, the antenna 106 may be configured for transmit - antenna diversity (e.g., transmit spatial diversity) via two or more transmit antennas.

[0030] One or more wireless audio receivers 104a through 104n may be configured to receive radio frequency signals 110 via respective antennas 108a through 108n of the one or more wireless audio receivers 104a through 104n. The one or more wireless audio receivers 104a through 104n may each be configured as a wide tuning wireless audio receiver capable of being tuned to two or more wireless communication channels. For example, the respective antennas 108a through 108n may be configured for wideband tuning such that the tuning of the respective antennas 108a through 108n may be dynamically changed and tuned to a wireless communication channel.

[0031] For ease of illustration, Figure 1 each of the antennas 108a through 108n is depicted as a single antenna. However, each of the one or more wireless receivers 104a through 104n may be configured with two or more antennas (not shown) to enable effective reception of the radio frequency signals 110. In other words, since two or more antennas are provided for each of the one or more wireless audio receivers 104a through 104n, the respective antennas 108a through 108n may each be configured for receive antenna diversity (e.g., receive space diversity).

[0032] The one or more wireless audio receivers 104a through 104n are located at respective positions within the radio frequency environment of the wireless audio system 100. The one or more wireless audio receivers 104a through 104n may be configured as mobile wireless audio receivers such that the positions of the respective wireless audio receivers 104a through 104n may be dynamically changed over time within the radio frequency environment. In some instances, the one or more wireless audio receivers 104a through 104n may be grouped based on wireless audio receiver grouping operations performed by the wireless audio transmitter 102 and / or the one or more wire audio receivers 104a through 104n to form a personal listening system for a stereo audio mix or a mono audio mix associated with the radio frequency signals 110.

[0033] Based on the wireless audio system conditions of the wireless audio system 100, the one or more wireless audio receivers 104a through 104n are configured to independently tune to the best wireless communication channel associated with the best carrier frequency to receive the radio frequency signals 110 transmitted by the wireless audio transmitter 102. For example, based on the conditions of the radio frequency environment of the wireless audio system 100, the one or more wireless audio receivers 104a through 104n may independently tune to the best wireless communication channel associated with the best carrier frequency (i.e., an improved or best carrier frequency selected from among redundantly transmitted carrier frequencies) to receive the radio frequency signals 110 transmitted by the wireless audio transmitter 102.

[0034] Tuning of the respective antennas 108a to n can be triggered based on respective interference conditions local to or near one or more wireless audio receivers 104a to n. The interference condition can be a condition for a radio frequency signal, where in addition to data (e.g., audio mix data) transmitted by the wireless audio transmitter 102, there is an undesired noise level (e.g., a certain amount of undesired radio frequency energy) on the wireless communication channel. Alternatively, the interference condition can be a condition for a radio frequency signal, where there is a certain amount of attenuation such that the radio frequency signal has an undesired signal-to-noise ratio.

[0035] When initially placed in an audio environment, one or more wireless audio receivers 104a to n can independently tune to a first wireless communication channel associated with a first carrier frequency to receive a radio frequency signal 110. However, at least one of the one or more wireless audio receivers 104a to n can detect an interference condition, or more generally, can detect a communication channel condition indicating an undesired audio quality of the radio frequency signal 110 transmitted on the first wireless communication channel. The at least one wireless audio receiver is then configured to determine whether the detected communication channel condition of the first wireless communication channel meets a communication channel condition threshold, and if so, the corresponding wireless audio receiver is configured to tune to a second wireless communication channel associated with a second carrier frequency different from the first carrier frequency, independent of the other wireless audio receivers 104a to n that have not experienced sufficient communication channel conditions, to receive the radio frequency signal 110.

[0036] In a non - limiting example, the wireless audio transmitter 102 transmits radio frequency signals 110 via both a first wireless communication channel associated with a first carrier frequency and a second wireless communication channel associated with a second carrier frequency. Additionally, both the wireless audio receiver 104a and the wireless audio receiver 104n are tuned to the first wireless communication channel to receive the radio frequency signals 110. However, in response to detecting communication channel conditions indicating an undesirable audio quality of the wireless audio receiver 104a via the first wireless communication channel, the wireless audio receiver 104a may switch the tuning of the wireless audio receiver 104a to the second wireless communication channel to receive the radio frequency signals 110 via the second wireless communication channel. Independent of the wireless audio receiver 104a, and due to the redundant transmission of the radio frequency signals 110 by the wireless audio transmitter 102 via the first wireless communication channel and the second wireless communication channel, the wireless audio receiver 104n may remain tuned to the first wireless communication channel such that while the wireless audio receiver 104n receives the radio frequency signals 110 via the first wireless communication channel, the wireless audio receiver 104a receives the radio frequency signals 110 via the second wireless communication channel. However, in response to detecting communication channel conditions indicating an undesirable audio quality of the wireless audio receiver 104n via the first wireless communication channel, the wireless audio receiver 104n may switch the tuning of the wireless audio receiver 104n to the second wireless communication channel (or another wireless communication channel associated with the redundant transmission of the radio frequency signals 110 by the wireless audio transmitter 102) to receive the radio frequency signals 110.

[0037] In some examples, a wireless audio receiver, such as the wireless audio receiver 104a, utilizes informed decisions related to the respective communication channel conditions of one or more candidate wireless communication channels to determine whether to switch the tuning of the wireless audio receiver 104a to a different wireless communication channel to receive the radio frequency signals 110. To provide informed decisions, a wireless audio receiver, such as the wireless audio receiver 104a, may analyze the respective communication channel conditions of one or more candidate wireless communication channels for receiving the radio frequency signals 110. Additionally or alternatively, a wireless audio receiver, such as the wireless audio receiver 104a, may compare the active communication channel conditions of the wireless communication channel currently receiving the radio frequency signals 110 with the communication channel conditions of one or more candidate wireless communication channels for alternatively receiving the radio frequency signals 110. For example, in response to detecting a first communication channel condition of the first wireless communication channel indicating an undesirable audio quality of the wireless audio receiver 104a via the first wireless communication channel, the wireless audio receiver 104a may compare the first communication channel condition (i.e., the attenuation level on the first wireless communication channel) with a second communication channel condition of the second wireless communication channel (e.g., any relative attenuation detected on the second wireless communication channel).

[0038] In response to the second communication channel condition of the second wireless communication channel being deemed more favorable than the first communication channel condition for receiving the radio frequency signal 110, the wireless audio receiver 104a may switch the tuning of the wireless audio receiver 104a to the second wireless communication channel to receive the radio frequency signal 110. However, in response to the second communication channel condition of the second wireless communication channel being deemed less favorable than the first communication channel condition for receiving the radio frequency signal 110, the wireless audio receiver 104a may not switch and may remain tuned to the first wireless communication channel. On the other hand, the wireless audio receiver 104a may attempt to repeat the above condition checking process and determine the feasibility of retuning to a third wireless communication channel to receive the radio frequency signal 110. Thus, informed decisions related to the respective communication channel conditions of one or more candidate wireless communication channels can further mitigate interference and / or improve other undesirable communication channel conditions for receiving the radio frequency signal 110.

[0039] In some instances, a wireless audio receiver, such as the wireless audio receiver 104a, utilizes timing information of a relevant wireless communication protocol used to perform communication between the wireless audio transmitter 102 and the wireless audio receiver to provide the time required to check the communication channel conditions of alternative communication channels as part of the informed decision-making process discussed above. For example, since there is a certain amount of synchronization overhead to maintain the desired synchronization between the wireless audio transmitter 102 and the wireless audio receiver, time can be provided for a wireless audio receiver (such as the wireless audio receiver 104a) to compare the local communication channel conditions of the wireless communication channel currently receiving the radio frequency signal 110 with the respective communication channel conditions of one or more candidate wireless communication channels. In some instances, a specific frame or packet for the relevant wireless communication protocol may initiate the condition checking process for the wireless communication channel.

[0040] The synchronization overhead may be available based on, but not limited to, the following: synchronization signals exchanged between the wireless audio transmitter 102 and the wireless audio receiver, clock synchronization between the wireless audio transmitter 102 and the wireless audio receiver, synchronization of the carrier frequencies between the wireless audio transmitter 102 and the wireless audio receiver, channel characteristics (e.g., amplitude, phase, and / or frequency response) between the wireless audio transmitter 102 and the wireless audio receiver, synchronization of frames or data packets between the wireless audio transmitter 102 and the wireless audio receiver, identification of frame markers or other frame structures for maintaining frame synchronization, hardware characteristics (such as hardware type) of the wireless audio transmitter 102 for transmitting the radio frequency signal 110, hardware characteristics (such as hardware type) of the wireless audio receiver for receiving the radio frequency signal 110, and / or other timing information between the wireless audio transmitter 102 and the wireless audio receiver.

[0041] Turn to communication channel conditions that may cause the transmitted wireless audio to independently switch to other candidate communication channels. Such communication channel conditions may include one or more conditions related to the first wireless communication channel and / or the corresponding wireless audio receiver, such as but not limited to: interference conditions of the first wireless communication channel, signal attenuation conditions associated with the first wireless communication channel, non-interference related conditions associated with the first wireless communication channel, position conditions of the corresponding wireless audio receiver within a radio frequency environment that may be more suitable for different carrier frequencies, and / or another type of condition related to the first wireless communication channel and / or the corresponding wireless audio receiver. For example, based on the determination that the interference condition of the first wireless communication channel meets the interference condition threshold, one or more wireless audio receivers 104a to n may be configured to independently tune to the second wireless communication channel. The second wireless communication channel may be associated with a second carrier frequency different from the first carrier frequency to receive the radio frequency signal 110. The interference condition may include any one of the following: noise condition, interference amplitude condition, signal-to-noise ratio condition, quality condition, bit error rate (BER) condition, error vector magnitude (EVM) condition, or another type of interference condition related to the interference level of the first wireless communication channel.

[0042] In another example, one or more wireless audio receivers 104a to n may be configured to independently tune to the second wireless communication channel based on the determination that the signal attenuation condition associated with the first wireless communication channel meets the signal attenuation condition threshold. The signal attenuation condition may be a condition for the wireless communication channel where no radio frequency signal is received via the wireless communication channel due to, for example, radio frequency loss between the wireless audio receiver and the wireless audio transmitter. For example, the signal attenuation condition may include any one of the following: frequency loss condition, communication failure condition, packet loss condition, or another type of signal attenuation condition related to the first wireless communication channel.

[0043] In another example, one or more wireless audio receivers 104a to n may be configured to independently tune to the second wireless communication channel based on the determination that the non-interference related condition associated with the first wireless communication channel meets the non-interference related condition threshold. For example, the non-interference related condition may include any one of the following: distortion condition, distortion condition, log-likelihood ratio (LLR) condition, or another type of non-interference related condition related to the first wireless communication channel.

[0044] In yet another example, to provide optimal frequency coverage for one or more wireless audio receivers 104a through n, the one or more wireless audio receivers 104a through n can be configured to independently tune to a second wireless communication channel based on a local determination corresponding to or most suitable for a defined region within the radio frequency environment based on the respective location of the corresponding wireless audio receiver. The optimal carrier frequency for the defined region can be manually established or configured by creating zones (e.g., audio zones, radio frequency environment partitions, partitions between wireless audio receivers, multiple transmitter configurations, etc.), or it can be independently learned by each respective wireless audio receiver based on an analysis of the received radio frequency signals 110 and other detected environmental factors.

[0045] Each of the one or more wireless audio receivers 104a through n can be configured to detect and optionally report its location or position within the radio frequency environment. This location can be detected via various means that will be apparent to those of ordinary skill in the art and can be a real-time position based on static location determination or a real-time position based on the movement of the one or more wireless audio receivers 104a through n within the radio frequency environment.

[0046] In a non-limiting example, both wireless audio receiver 104a and wireless audio receiver 104n can be tuned to a wireless communication channel associated with a particular carrier frequency to receive radio frequency signals 110 broadcast by wireless audio transmitter 102 via the wireless communication channel and one or more other wireless communication channels. Wireless audio receiver 104a can be located at a first position within the radio frequency environment of wireless audio system 100, and wireless audio receiver 104n can be located at a second position within the radio frequency environment. Both wireless audio receiver 104a and wireless audio receiver 104n can independently determine whether the communication channel conditions of the wireless communication channel employed by the respective wireless audio receiver meet a communication channel condition threshold.

[0047] For example, both wireless audio receiver 104a and wireless audio receiver 104n can independently determine whether the interference conditions of the wireless communication channel meet an interference condition threshold. In this example, the first position of wireless audio receiver 104a can be associated with a certain amount of interference such that the interference conditions of the wireless communication channel meet the interference condition threshold of wireless audio receiver 104a. The second position of wireless audio receiver 104n can be associated with a different level of interference such that the interference conditions of the wireless communication channel do not meet the interference condition threshold of wireless audio receiver 104n. Accordingly, wireless audio receiver 104a is configured to tune to a different wireless communication channel associated with a different carrier frequency to receive radio frequency signals 110, while wireless audio receiver 104n is configured to remain tuned to the original wireless communication channel to receive radio frequency signals 110.

[0048] The communication channel conditions of a wireless communication channel (e.g., interference conditions, signal attenuation conditions, and / or non-interference related conditions) can be determined, for example, based on a wireless communication channel measurement device, an antenna measurement device, a radio frequency sensitivity measurement device, a spectrum analyzer device, an electromagnetic interference measurement device, or another type of monitoring device included in one or more wireless audio receivers 104a to n. Additionally, communication channel condition thresholds (e.g., interference condition thresholds, signal attenuation condition thresholds, and / or non-interference related condition thresholds) can be determined based on one or more signal metrics of the wireless communication channel.

[0049] For example, the interference condition threshold can correspond to a noise threshold, an interference amplitude threshold, a signal-to-noise ratio threshold, a BER threshold, an EVM threshold, or another type of threshold related to the amount of interference. The signal attenuation condition threshold can correspond to a frequency loss threshold, a signal attenuation threshold, a data packet loss threshold, or another type of threshold related to the identification of signal attenuation. The non-interference related condition threshold can correspond to a distortion threshold, a distortion threshold, an LLR threshold, or another type of signal metric threshold.

[0050] In various instances, the communication channel condition threshold (e.g., interference condition threshold, signal attenuation condition threshold, and / or non-interference related condition threshold) can be determined to be satisfied and / or triggered based on the communication channel condition threshold being sustained (i.e., the communication channel condition threshold is met) for a certain time interval. Confirming that the communication channel condition persists for a predetermined time interval prevents the wireless audio receivers 104a to n from making unnecessary tuning and / or switching from a satisfactory wireless communication channel when temporary or intermittent communication channel conditions occur.

[0051] One or more machine learning models configured for interference detection can be used to learn and / or train the communication channel condition thresholds (e.g., interference condition thresholds, signal attenuation condition thresholds, and / or non-interference related condition thresholds). Alternatively, the communication channel condition thresholds can be predetermined based on the type of radio frequency environment of the wireless audio receiver. In various instances, the communication channel condition thresholds can vary and are thus determined individually based on the type of codec and / or other hardware integrated within the wireless audio receiver.

[0052] Each of one or more wireless audio receivers 104a through 104n may also be configured to report tuning update data to the wireless audio transmitter 102. The tuning update data may indicate that a respective one of the one or more wireless audio receivers 104a through 104n has tuned from a wireless communication channel to a new wireless communication channel. For example, the tuning update data may include a wireless communication channel identifier associated with the new wireless communication channel of the respective wireless audio receiver, a carrier frequency value associated with the new wireless communication channel of the respective wireless audio receiver, a wireless audio transmitter identifier associated with the respective wireless audio receiver, location data associated with the respective wireless audio receiver, communication channel condition data associated with the wireless communication channel that triggered tuning to the new wireless communication channel of the respective wireless audio receiver, other data associated with the respective wireless audio receiver, other data associated with the wireless communication channel, and / or other data associated with the new wireless communication channel.

[0053] In some instances, one or more other wireless communication channels that redundantly transmit the radio frequency signal 110 may include a plurality of wireless communication channels each associated with a different carrier frequency. Additionally, the wireless audio transmitter 102 may receive first tuning update data from a first wireless audio receiver of the one or more wireless audio receivers 104a through 104n indicating that the first wireless audio receiver has tuned from a wireless communication channel to a first channel of the plurality of wireless communication channels. The wireless audio transmitter 102 may also receive second tuning update data from a second wireless audio receiver of the one or more wireless audio receivers 104a through 104n indicating that the second wireless audio receiver has tuned from a wireless communication channel to a second channel of the plurality of wireless communication channels. The second wireless communication channel may be associated with a carrier frequency different from the first wireless communication channel. Thus, in some instances, the wireless audio transmitter 102 may receive tuning update data from two or more wireless audio receivers that have transitioned from a wireless communication channel to respective new and separate wireless communication channels.

[0054] In an example, the wireless audio transmitter 102 may transmit the radio frequency signal 110 via at least a first wireless communication channel associated with a first carrier frequency and a second wireless communication channel associated with a second carrier frequency different from the first carrier frequency. Additionally, the wireless audio receiver 104a may be the first wireless audio receiver that receives the radio frequency signal 110 transmitted by the wireless audio transmitter 102, and the wireless audio receiver 104n may be the second wireless audio receiver that also receives the radio frequency signal 110 transmitted by the wireless audio transmitter 102.

[0055] The wireless audio receiver 104a can be tuned to a first wireless communication channel associated with a first carrier frequency or a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110. Additionally, the wireless audio receiver 104a can be tuned to a first wireless communication channel associated with a first carrier frequency or a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110.

[0056] The wireless audio receiver 104a can be tuned to a first wireless communication channel associated with a first carrier frequency to receive the radio frequency signal 110, and the wireless audio receiver 104n can also be tuned to a first wireless communication channel associated with a first carrier frequency to receive the radio frequency signal 110.

[0057] In another example, the wireless audio receiver 104a can be tuned to a first wireless communication channel associated with a first carrier frequency to receive the radio frequency signal 110, and the wireless audio receiver 104n can be tuned to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110.

[0058] In another example, the wireless audio receiver 104a can be tuned to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110, and the wireless audio receiver 104n can be tuned to a first wireless communication channel associated with a first carrier frequency to receive the radio frequency signal 110.

[0059] In yet another example, the wireless audio receiver 104a can be tuned to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110, and the wireless audio receiver 104n can also be tuned to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110.

[0060] The wireless audio receiver 104a and the wireless audio receiver 104n can also be independently tuned to different wireless communication channels based on the respective communication channel conditions. For example, in an instance where both the wireless audio receiver 104a and the wireless audio receiver 104n are tuned to a first wireless communication channel associated with a first carrier frequency to receive the radio frequency signal 110, the wireless audio receiver 104a can be independently tuned to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110 based on a determination that the communication channel conditions of the first wireless communication channel meet a communication channel condition threshold. Additionally, the wireless audio receiver 104n can be independently tuned to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal 110 based on a second determination that the second communication channel conditions of the first wireless communication channel meet a second communication channel condition threshold.

[0061] The second communication channel condition may be different from the communication channel condition. In an alternative instance, the second communication channel condition may correspond to the communication channel condition. Additionally or alternatively, the second communication channel condition threshold may be different from the communication channel condition threshold. In an alternative instance, the second communication channel condition threshold may correspond to the communication channel condition threshold.

[0062] In an instance where the wireless audio transmitter 102 additionally transmits the radio frequency signal 110 via at least a third wireless communication channel associated with a third carrier frequency different from the first carrier frequency and the second carrier frequency, the wireless audio receiver 104a and / or the wireless audio receiver 104n may alternatively be independently tuned to the third wireless communication channel associated with the third carrier frequency to receive the radio frequency signal 110. For example, based on a second determination that the second communication channel condition of the first wireless communication channel meets the second communication channel condition threshold, the wireless audio receiver 104n may alternatively be tuned to the third wireless communication channel associated with the third carrier frequency to receive the radio frequency signal 110.

[0063] In some instances, the wireless audio transmitter 102 may be configured as two or more wireless audio transmitters. For example, the wireless audio transmitter 102 may include a first wireless audio transmitter that transmits the radio frequency signal 110 via a first wireless communication channel associated with a first carrier frequency. Additionally, the wireless audio transmitter 102 may include at least a second wireless audio transmitter that transmits the radio frequency signal 110 via a second wireless communication channel associated with a second carrier frequency different from the first carrier frequency.

[0064] It should be understood that in some instances, the wireless audio transmitter 102 may include more than two wireless audio transmitters. For example, the wireless audio transmitter 102 may additionally include at least a third wireless audio transmitter that transmits the radio frequency signal 110 via a third wireless communication channel associated with a third carrier frequency different from the first carrier frequency and the second carrier frequency.

[0065] Figure 2 An example wireless audio receiver device 152 configured according to one or more embodiments of the present disclosure is shown. The wireless audio receiver device 152 may be configured to perform Figure 1 one or more of the techniques described in and / or one or more other techniques described herein. In one or more embodiments, the wireless audio receiver device 152 may be embedded with wireless audio receivers from one or more of the wireless audio receivers 104a through n.

[0066] In some cases, the wireless audio receiver device 152 can be a computing system communicatively coupled to and configured to control one or more circuit modules associated with wireless audio processing. For example, the wireless audio receiver device 152 can be a computing system communicatively coupled to one or more circuit modules regarding wireless audio processing. The wireless audio receiver device 152 can include a processor 154, a memory 156, an interference mitigation circuit 158, a wireless audio processing circuit 160, an input / output circuit 162, and / or a communication circuit 164, or communicate with them in other ways. In some instances, the processor 154 (which can include multiple or coprocessors or any other processing circuits associated with the processor) can communicate with the memory 156.

[0067] The memory 156 can include non-transitory memory circuits and can include one or more volatile and / or non-volatile memories. In some instances, the memory 156 can be an electronic storage device (e.g., a computer-readable storage medium) configured to store data retrievable by the processor 154. In some instances, the data stored in the memory 156 may include radio frequency signal data, audio data, stereo audio signal data, mono audio signal data, etc., for enabling the device to perform various functions or methods according to embodiments of the present invention described herein.

[0068] In some instances, the processor 154 can be embodied in a variety of different ways. For example, the processor 154 can be embodied as one or more of various hardware processing devices, such as a central processing unit (CPU), a microprocessor, a coprocessor, a digital signal processor (DSP), an advanced RISC machine (ARM), a field programmable gate array (FPGA), a neural processing unit (NPU), a graphics processing unit (GPU), a system on a chip (SoC), a cloud server processing element, a controller, or a processing element with or without an accompanying DSP. The processor 154 can also be embodied in various other processing circuits, including integrated circuits, such as, for example, a microcontroller unit (MCU), an ASIC (application specific integrated circuit), a hardware accelerator, a cloud computing chip, or a dedicated electronic chip. Additionally, in some instances, the processor 154 can include one or more processing cores configured to execute independently. A multi-core processor can implement multi-processing within a single physical package. Additionally or alternatively, the processor 154 can include one or more processors configured in series via a bus to enable independent execution of instructions, pipelining, and / or multi-threading.

[0069] In an example, the processor 154 may be configured to execute instructions stored in the memory 156 or otherwise accessible to the processor 154, such as computer program code or instructions. Alternatively or additionally, the processor 154 may be configured to perform hard-coded functions. Thus, whether configured by hardware or software instructions or by a combination thereof, the processor 154 may represent a computing entity (e.g., physically embodied in circuitry) configured to perform operations in accordance with embodiments of the present invention described herein. For example, when the processor 154 is embodied as a CPU, DSP, ARM, FPGA, ASIC, or the like, the processor may be configured as hardware for performing operations of embodiments of the present invention. Alternatively, when the processor 154 is embodied as executing software or computer program instructions, the instructions may specifically configure the processor 154 to perform the algorithms and / or operations described herein when the instructions are executed. However, in some cases, the processor 154 may be a processor of a device specifically configured to adopt embodiments of the present invention by further configuring the processor with instructions for performing the algorithms and / or operations described herein. The processor 154 may further include a clock, an arithmetic logic unit (ALU), and logic gates configured to support the operation of the processor 154, among other things.

[0070] In one or more examples, the wireless audio receiver device 152 may include an interference mitigation circuit 158. The interference mitigation circuit 158 may be any device embodied as hardware or a combination of hardware and software, configured to perform one or more functions disclosed herein related to one or more wireless audio receivers 104a-n to provide transmission redundancy for the wireless audio system. In one or more examples, the wireless audio receiver device 152 may include a wireless audio processing circuit 160. The wireless audio processing circuit 160 may be any device embodied as hardware or a combination of hardware and software, configured to perform one or more functions disclosed herein related to audio processing of the radio frequency signal 110. In one or more examples, the wireless audio processing circuit 160 may be configured to perform audio processing to convert one or more portions of the radio frequency signal 110 into an audio signal 406 for the listening device 402.

[0071] In certain examples, the wireless audio receiver device 152 may include an input / output circuit 162, which in turn may communicate with the processor 154 to provide output to a user and, in some examples, receive indications of user input. The input / output circuit 162 may include a user interface and may include a display. In some examples, the input / output circuit 162 may further include a keyboard, a touch screen, a touch area, soft keys, buttons, knobs, or other input / output mechanisms.

[0072] In some instances, the wireless audio receiver device 152 may include a communication circuit 164. The communication circuit 164 may be any device embodied as hardware or a combination of hardware and software that is configured to receive and / or transmit data from / to a network and / or any other device or module that communicates with the wireless audio receiver device 152. In this regard, the communication circuit 164 may include, for example, an antenna or one or more other communication devices for enabling communication with a wired or wireless communication network. For example, the communication circuit 164 may include an antenna, one or more network interface cards, buses, switches, routers, modems, and supporting hardware and / or software, or any other device suitable for enabling communication via a network. Additionally or alternatively, the communication circuit 164 may include circuitry for interacting with one or more antennas to cause transmission of signals via the one or more antennas or for processing signals received via the one or more antennas (e.g., radio frequency signal 110).

[0073] Figure 3 Shown is a wireless audio transmitter system 300 that facilitates transmission redundancy of the wireless audio system 100 in accordance with one or more embodiments of the present disclosure. The wireless audio transmitter system 300 includes a wireless audio transmitter 102. To facilitate transmission redundancy of the radio frequency signal 110, the wireless audio transmitter 102 may simultaneously transmit the radio frequency signal 110 at two or more carrier frequencies via an antenna 106. For example, the wireless audio transmitter 102 may simultaneously transmit the radio frequency signal 110 via two or more wireless communication channels 202a-n. In some instances, the wireless audio transmitter system 300 includes multiple antennas for simultaneously transmitting the radio frequency signal 110 at multiple carrier frequencies.

[0074] The wireless communication channel 202a may be, for example, a first wireless communication channel associated with a first carrier frequency of the broadcast radio frequency signal 110. The wireless communication channel 202n may also be, for example, a second wireless communication channel associated with a second carrier frequency different from the first carrier frequency that redundantly broadcasts the radio frequency signal 110. It should be understood that in some instances, the wireless audio transmitter 102 may redundantly broadcast the radio frequency signal 110 via more than two wireless communication channels each associated with a unique carrier frequency.

[0075] Figure 4A Shown is a wireless audio receiver system 400 that facilitates transmission redundancy of the wireless audio system 100 in accordance with one or more embodiments of the present disclosure. The wireless audio receiver system 400 includes a wireless audio receiver 104. The wireless audio receiver 104 may correspond to a wireless audio receiver (e.g., wireless audio receiver 104a or wireless audio receiver 104n) from one or more of the wireless audio receivers 104a-n in the wireless audio system 100.

[0076] The depicted wireless audio receiver 104 can utilize the antenna 108 of the wireless audio receiver 104 to tune to a wireless communication channel 202a associated with a first carrier frequency to receive a radio frequency signal 110. In one example, the wireless audio receiver 104 can select and / or tune to the wireless communication channel 202a based on a wireless communication channel scanning operation performed by the wireless audio receiver system 400. The wireless communication channel scanning operation can scan any redundant wireless communication channels used by the wireless audio transmitter 102 to broadcast the radio frequency signal 110.

[0077] The wireless audio receiver 104 can also establish a connection with the wireless audio transmitter 102 via the wireless communication channel scanning operation. For example, the wireless audio receiver 104 can establish a connection with the wireless audio transmitter 102 via the wireless communication channel 202a based on the wireless communication channel scanning operation. The wireless audio receiver 104 can establish an initial connection via the wireless communication channel 202a based on one or more predefined wireless channel rules. In an example, the one or more predefined wireless channel rules can include one or more spacing rules to optimize the use of the wireless communication channel and / or provide an optimal separation between the wireless communication channels employed by the respective wireless audio receivers. In another example, the one or more predefined wireless channel rules can additionally or alternatively include timing rules such that the communication channel conditions of the wireless communication channel are satisfied for a certain period of time before tuning to a different wireless communication channel. In this way, the tuning of the wireless audio receiver 104 can be configured to prevent excessive switching of the wireless communication channel due to intermittent or transient interference associated with the wireless communication channel.

[0078] When it is determined that the communication channel conditions of the wireless communication channel 202a meet a communication channel condition threshold, the wireless audio receiver 104 is configured to utilize the antenna 108 to tune to a wireless communication channel 202n associated with a second carrier frequency to receive the radio frequency signal 110, as Figure 4B shown. For example, based on the determination that the interference conditions of the wireless communication channel 202a meet an interference condition threshold, the wireless audio receiver 104 can utilize the antenna 108 of the wireless audio receiver 104 to tune to a wireless communication channel 202n associated with a second carrier frequency to receive the radio frequency signal 110. To provide optimized tuning for the wireless audio receiver 104, the wireless audio receiver 104 can utilize the antenna 108 of the wireless audio receiver 104 to tune to the wireless communication channel 202n based on the communication channel condition threshold being met for a certain time interval.

[0079] The second carrier frequency may be different from the first carrier frequency. In a non-limiting example, the first carrier frequency may correspond to 174 MHz, and the second carrier frequency may correspond to 244 MHz. However, it should be understood that the first carrier frequency and / or the second carrier frequency may be different carrier frequency values within a frequency range, for example, from about 174 MHz to about 6 GHz. In some instances, based on a determination that the communication channel conditions of the wireless communication channel 202a meet a communication channel condition threshold, the wireless audio receiver 104 may switch between a first antenna associated with the wireless communication channel 202a and a second antenna associated with the second wireless communication channel 202n.

[0080] Additionally, it should be understood that the wireless audio receiver 104 may tune to the wireless communication channel 202n based on one or more other conditions of the wireless communication channel 202a by using the antenna 108 of the wireless audio receiver 104. For example, the wireless audio receiver 104 may tune to the wireless communication channel 202n based on the detection of a signal attenuation condition, a non-interference related condition, or another undesirable condition associated with the wireless communication channel 202a.

[0081] In various instances, the wireless audio receiver 104 may establish a connection via the wireless communication channel 202n based on one or more predefined wireless channel rules. For example, based on a determination that the communication channel conditions of the wireless communication channel 202a meet a communication channel condition threshold, the wireless audio receiver 104 may select the wireless communication channel 202n from a list of wireless communication channels and / or based on one or more predefined wireless channel rules as further described herein. In some instances, the wireless audio receiver 104 may iterate the wireless communication channel selection process via multi-hop, where each hop involves a comparison of the communication channel conditions of each correspondingly redundantly transmitted wireless communication channel with a corresponding wireless communication channel threshold.

[0082] In some instances, the determination that the communication channel condition of the wireless communication channel 202a meets the communication channel condition threshold can be determined relative to the individual communication channel conditions of the wireless communication channels 202n. For example, in response to the communication channel condition of the wireless communication channel 202a meeting the communication channel condition determination, the wireless audio receiver 104 can additionally compare the individual communication channel conditions of the second wireless communication channel with the communication channel condition threshold. Additionally, based on the determination that the individual communication channel conditions of the second wireless communication channel do not meet the communication channel condition threshold, the wireless audio receiver 104 can be configured to tune the antenna 108 to the wireless communication channel 202n associated with the second carrier frequency to receive the radio frequency signal 110. However, based on the determination that the individual communication channel conditions of the second wireless communication channel meet the communication channel condition threshold, the wireless audio receiver 104 can maintain the tuning via the wireless communication channel 202a, or the wireless audio receiver 104 can tune to a different wireless communication channel with more desirable communication channel conditions.

[0083] In some instances, the wireless audio receiver 104 can alternatively compare the individual communication channel conditions of the second wireless communication channel with a communication channel improvement threshold different from the communication channel condition threshold. Additionally, based on the determination that the individual communication channel conditions of the second wireless communication channel meet the communication channel improvement threshold, the wireless audio receiver 104 can be configured to tune the antenna 108 to the wireless communication channel 202n associated with the second carrier frequency to receive the radio frequency signal 110. The communication channel improvement threshold can be determined based on one or more signal quality metrics of the wireless communication channel. For example, the communication channel improvement threshold can be used to indicate a certain degree of improvement achieved by switching the wireless communication channel to receive the radio frequency signal 110. In some instances, the communication channel improvement threshold can be based on a certain degree of predicted improvement relative to interference, signal attenuation, and / or another type of communication channel condition. Therefore, the wireless audio receiver 104 can be retuned to the wireless communication channel 202n based on one or more informed decisions that the wireless communication channel 202n is sufficiently available for receiving the radio frequency signal 110 and / or the wireless communication channel 202n is more favorable for receiving the radio frequency signal 110 than the wireless communication channel 202a.

[0084] In certain instances, the wireless audio transmitter 102 can receive data from wireless audio receivers among one or more wireless audio receivers 104a through n. For example, in response to the wireless audio receiver 104 determining that the communication channel condition of the wireless communication channel 202a meets the communication channel condition threshold, the wireless audio transmitter 102 can receive data from the wireless audio receiver 104 based on or by tuning the wireless audio receiver 104 from the wireless communication channel 202a to the wireless communication channel 202n.

[0085] Data received from the wireless audio receiver 104 is referred to as "tuning update data" and may indicate that the wireless audio transmitter 102 has tuned from a wireless communication channel (e.g., wireless communication channel 202a) to a new wireless communication channel (e.g., wireless communication channel 202n). The tuning update data may include a wireless communication channel identifier associated with the new wireless communication channel of the wireless audio receiver 104, a carrier frequency value associated with the new wireless communication channel of the wireless audio receiver 104, a wireless audio transmitter identifier associated with the wireless audio receiver 104, location data associated with the wireless audio receiver 104, communication channel condition data associated with the wireless communication channel (e.g., wireless communication channel 202a) that triggered the tuning to the new wireless communication channel of the wireless audio receiver 104, other data associated with the wireless audio receiver 104, other data associated with the wireless communication channel, and / or other data associated with the new wireless communication channel.

[0086] In this regard, the wireless audio transmitter 102 may redundantly transmit the radio frequency signal 110 via the wireless communication channel 202a and the wireless communication channel 202n. Additionally, the wireless audio receiver 104 may initially be tuned to the wireless communication channel 202a to receive the radio frequency signal 110. However, after the wireless audio receiver 104 is tuned to the wireless communication channel 202n based on a determination that the communication channel conditions of the wireless communication channel 202a meet a communication channel condition threshold, the wireless audio transmitter 102 may receive tuning update data from the wireless audio receiver 104. The tuning update data received by the wireless audio transmitter 102 may indicate that the wireless audio receiver 104 has tuned from the wireless communication channel 202a to the wireless communication channel 202n.

[0087] In a non-limiting example, the wireless audio transmitter 102 may receive a first wireless communication channel identifier associated with the wireless communication channel 202a from the wireless audio receiver 104 based on the tuning of the wireless audio receiver 104 via the wireless communication channel 202a. Then, based on switching the tuning of the wireless audio receiver 104 to the wireless communication channel 202n, the wireless audio transmitter 102 may receive a second wireless communication channel identifier associated with the wireless communication channel 202n from the wireless audio receiver 104. In various examples, the wireless audio transmitter 102 may additionally or alternatively receive communication channel condition data associated with the tuning of the wireless audio receiver 104 from the wireless communication channel 202a to the wireless communication channel 202n and / or other tuning update data as further disclosed herein.

[0088] The wireless audio transmitter 102 can also be configured to receive corresponding tuning update data from a corresponding wireless audio transmitter in the radio frequency environment of the wireless audio system. For example, the wireless audio transmitter 102 can receive first tuning update data from the wireless audio receiver 104a based on the tuning of the wireless audio receiver 104a from a wireless communication channel (e.g., wireless communication channel 202a) to a new wireless communication channel (e.g., wireless communication channel 202n). Additionally, the wireless audio transmitter 102 can receive second tuning update data from the wireless audio receiver 104n based on the tuning of the wireless audio receiver 104n from a wireless communication channel (e.g., wireless communication channel 202a) to a new wireless communication channel (e.g., wireless communication channel 202n).

[0089] Figure 5 A wireless audio receiver system 500 that promotes transmission redundancy of the wireless audio system 100 in accordance with one or more embodiments of the present disclosure is shown. The wireless audio receiver system 500 includes a wireless audio receiver 104 and a listening device 402. The wireless audio receiver 104 is communicatively coupled to the listening device 402 via an audio channel 404. The audio channel 404 can be a wireless audio channel or a wired audio channel. The listening device 402 can be an in-ear monitor, a headset, headphones, a speaker, or another type of listening device. The wireless audio receiver 104 can transmit an audio signal 406 to the listening device via the audio channel 404. The audio signal 406 can include audio data associated with one or more portions of a radio frequency signal 110 received via wireless communication channels from two or more wireless communication channels 202a through n.

[0090] Embodiments of the present disclosure will be described below with reference to block diagrams and flowchart illustrations. Therefore, it should be understood that each block of the block diagrams and flowchart illustrations can be implemented in the form of a computer program product, a fully hardware embodiment, a combination of hardware and a computer program product, and / or instructions, operations, steps, and similar terms (e.g., executable instructions, instructions for execution, program code, etc.) that are interchangeably used on a computer-readable storage medium for execution by a device, system, computing device / entity, computing entity, etc. For example, the retrieval, loading, and execution of code can be performed sequentially such that one instruction is retrieved, loaded, and executed at a time.

[0091] In some example embodiments, the retrieval, loading, and / or execution can be performed in parallel such that multiple instructions are retrieved, loaded, and / or executed together. Therefore, such embodiments can produce a specially configured machine that executes the steps or operations specified in the block diagrams and flowchart illustrations. Accordingly, the block diagrams and flowchart illustrations support various combinations of embodiments for executing the specified instructions, operations, or steps.

[0092] Figure 6 is in accordance with, for exampleFigure 2 Flowchart of an example process 600 for a wireless audio receiver device 152 shown in FIG. to mitigate interference associated with a radio frequency signal received by the wireless audio receiver. Through various operations of process 600, the wireless audio receiver device 152 enhances the quality and / or reliability of audio associated with the radio frequency signal. Process 600 begins at operation 602, which tunes to a first wireless communication channel associated with a first carrier frequency to receive the radio frequency signal. For example, to receive a radio frequency signal via the first carrier frequency, the antenna and / or tuning circuit of the wireless audio receiver is tuned to the first wireless communication channel such that the first carrier frequency is selected as the communication mode of the wireless audio receiver. Based on a determination that the communication channel conditions of the first wireless communication channel meet a communication channel condition threshold, operation 604 tunes to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal, the second carrier frequency being different from the first carrier frequency. Additionally, operation 604 tunes to the second wireless communication channel based on a determination that the interference conditions of the first wireless communication channel meet an interference condition threshold. In embodiments where the wireless audio receiver device 152 includes two or more antennas (i.e., receive antenna diversity), tuning operation 604 includes switching to an alternative antenna tuned to the second wireless communication channel. In some instances, the interference conditions include: noise conditions, interference amplitude conditions, signal-to-noise ratio conditions, quality conditions, BER conditions, EVM conditions, or another type of interference condition related to the degree of interference of the first wireless communication channel.

[0093] Figure 7 is a flowchart of an example process 700 for a wireless audio transmitter 102, for example, to mitigate interference associated with a radio frequency signal transmitted by the wireless audio transmitter. Through various operations of process 700, the wireless audio transmitter 102 enhances the quality and / or reliability of audio received by a wireless audio receiver. Process 700 begins at operation 702, which transmits a radio frequency signal via a wireless communication channel associated with a first carrier frequency. At operation 704, the radio frequency signal is redundantly transmitted via one or more other wireless communication channels associated with different carrier frequencies, respectively.

[0094] In some instances, the radio frequency signals redundantly transmitted via the wireless communication channel and one or more other wireless communication channels include corresponding audio payloads. In some instances, the radio frequency signals redundantly transmitted via the wireless communication channel and one or more other wireless communication channels include encoded information within sideband portions of the radio frequency signal corresponding to the audio payload. In some instances, the radio frequency signals redundantly transmitted via the wireless communication channel and one or more other wireless communication channels additionally or alternatively include control information corresponding to the respective wireless communication channels.
