Description

Technical Field

[0001] The present application relates to the technical field of sound cards, and in particular to a sound card and a sound card system. Background Art

[0002] An external sound card is an audio device that connects to your computer via an external interface (such as USB or Thunderbolt). Unlike integrated or built-in sound cards, external sound cards are independent audio processing devices with their own dedicated audio processing chips and circuitry, providing higher-quality audio output.

[0003] In application scenarios such as multi-person live broadcasts, the external sound card in related technologies can usually only communicate with the computer and send the audio data processed by the external sound card to the computer. Since the microphone cannot communicate directly with the external sound card, the real-time audio data collected by the microphone cannot be sent directly to the external sound card, resulting in the real-time audio data collected by the microphone not being able to enjoy the high-quality sound after professional processing by the external sound card. Summary of the Invention

[0004] The embodiments of the present application provide a sound card and a sound card system, which can solve the problem in the related art that the real-time audio data collected by the microphone cannot be directly sent to the external sound card because the microphone cannot communicate directly with the external sound card, resulting in the real-time audio data collected by the microphone not being able to enjoy the high-quality sound after professional processing by the external sound card.

[0005] In a first aspect, an embodiment of the present application provides a sound card; the sound card includes a shell, at least one wireless module and a control module, at least one wireless module is arranged in the shell, the control module is arranged in the shell, and the control module is electrically connected to the at least one wireless module to control the operation of the at least one wireless module, each wireless module is used to wirelessly communicate with at least one microphone, so that each wireless module can send real-time audio data collected by at least one microphone of the corresponding communication to the control module, when the sound card is used to wirelessly communicate with multiple microphones, each wireless module can also send the audio data received from the control module to at least one microphone of the corresponding communication, so that each microphone can selectively monitor the audio data of the remaining microphones, and the audio data includes real-time audio data and / or processed audio data obtained after processing by the control module.

[0006] In a second aspect, an embodiment of the present application provides a sound card system; the sound card system includes at least one microphone and the above-mentioned sound card, and each wireless module communicates wirelessly with the at least one microphone.

[0007] Based on the sound card and sound card system of the embodiment of the present application, by designing wireless modules to communicate wirelessly with at least one microphone, each wireless module can send real-time audio data collected by the corresponding at least one microphone to the control module, so that the control module processes the real-time audio data collected by the microphone, and the real-time audio data collected by the microphone can be processed by the control module to enjoy professional-grade sound effects. By designing wireless modules to communicate wirelessly with at least one microphone, compared with the sound card connected to the microphone through a wired method, the use range and use distance of the microphone that wirelessly communicates with the wireless module are more flexible, free from the constraints of wires, and the user does not need to worry about the range of use being limited due to the length of the wires. When the sound card communicates wirelessly with multiple microphones, each wireless module can also be designed to send the audio data received from the control module to the corresponding at least one microphone, so that each microphone can selectively monitor the audio data of the remaining microphones. In this way, the user can understand real-time feedback through monitoring to ensure voice quality, while also effectively improving the interactive experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] Please refer to Figure 1 The present application proposes a sound card system 1 , which includes a microphone 10 and a sound card 20 .

[0023] The microphone 10 is used as an audio device in the sound card system 1 for collecting the sound emitted by the user to form real-time audio data.

[0024] There is at least one microphone 10. For example, when there is only one microphone 10, the microphone 10 wirelessly communicates with the sound card 20 so that the sound card 20 can process the real-time audio data collected by the microphone 10. For another example, when there are multiple microphones 10 (two or more), the multiple microphones 10 wirelessly communicate with the sound card 20 so that the sound card 20 can process the real-time audio data collected by the multiple microphones 10.

[0025] The microphone 10 may be a wireless microphone 10a or a wireless headset 10b. Figure 2 As shown, when the microphone 10 is a wireless microphone 10a, the sound card system 1 further includes a monitoring device 30 (such as headphones), which is used for wired communication with the wireless microphone 10a. In this case, the user needs to monitor the audio data (such as real-time audio data and processed audio data described below) received by the wireless microphone 10a in real time through the monitoring device 30 that is in communication with the wireless microphone 10a. For another example, Figure 3 As shown, when microphone 10 is a wireless headset 10b, the user can directly monitor the audio data received by wireless headset 10b in real time through wireless headset 10b. It should be noted that when microphone 10 is a wireless microphone 10a, the number of monitoring devices 30 is at least one. In actual practice, the user can select a reasonable number of monitoring devices 30 based on actual needs. Typically, each wireless microphone 10a is configured with one monitoring device 30.

[0026] like Figure 4 As shown, the sound card 20 serves as an audio device in the sound card system 1 for processing the real-time audio data collected by the microphone 10 and obtaining processed audio data.

[0027] The sound card 20 includes a housing (not shown in the figure), a wireless module 21 and a control module 22 .

[0028] The housing serves as the outer shell of the sound card 20. The specific material of the housing is not limited here, and designers can reasonably select it based on actual needs. For example, the housing material can be, but is not limited to, ABS (Acrylonitrile-Butadiene-Styrene Copolymer) plastic, PC (Polycarbonate) plastic, or aluminum alloy. The specific shape of the housing is not limited here, and designers can reasonably design it based on actual needs. For example, the housing can be, but is not limited to, a rectangular parallelepiped or cylindrical shape.

[0029] The wireless module 21 serves as the wireless communication unit of the sound card 20. The wireless module 21 is used to wirelessly communicate with the microphone 10. On the one hand, the wireless module 21 is used to receive real-time audio data collected by the microphone 10. On the other hand, the wireless module 21 is used to send the processed audio data obtained after processing by the control module 22 to the microphone 10, and / or send the real-time audio data that has not been processed by the control module 22 to the microphone 10.

[0030] The wireless module 21 is disposed in the housing. The specific arrangement between the wireless module 21 and the housing is not limited here, and designers can make reasonable designs based on actual needs. For example, the wireless module 21 can be independent of the housing. In this case, the wireless module 21 can be fixedly connected to the housing by, but not limited to, snap-fitting or plugging (e.g., the housing has a plug-in port, and the wireless module 21 is detachably connected to the plug-in port). For another example, the wireless module 21 can also be integrated into the housing (i.e., the wireless module 21 and the housing are of a non-detachable, one-piece design). In this case, the wireless module 21 can be fixedly connected to the housing by, but not limited to, gluing or riveting.

[0031] The number of the wireless module 21 is at least one.

[0032] The control module 22 serves as the control center of the sound card 20 and is used to process the real-time audio data collected by the microphone 10 and obtain processed audio data. The specific structure of the control module 22 will be described in detail below.

[0033] The control module 22 is disposed within the housing. The specific arrangement of the control module 22 and the housing is not limited herein, and designers may design the arrangement appropriately based on actual needs. For example, the control module 22 may be, but is not limited to, detachably connected to the housing via at least one of a screw connection, a snap connection, or a plug-in connection. In another example, the control module 22 may be, but is not limited to, permanently connected to the housing via adhesive bonding or riveting.

[0034] The control module 22 is electrically connected to the at least one wireless module 21 to control the operation of the at least one wireless module 21 .

[0035] Each wireless module 21 is used to wirelessly communicate with at least one microphone 10, so that each wireless module 21 can send real-time audio data collected by the corresponding at least one microphone 10 to the control module 22. It should be noted that at this time, the control module 22 can process the real-time audio data according to the received control signal (such as the user operating the input module 24 of the sound card 20 to generate a corresponding control signal, specifically the first control signal) according to the control signal to obtain processed audio data, and the control module 22 can also not process the real-time audio data according to the control signal.

[0036] like Figure 4As shown, for example, when the number of wireless modules 21 is one and the number of microphones 10 is also one, the one wireless module 21 is used to wirelessly communicate with the one microphone 10, so that the real-time audio data collected by the one microphone 10 can be sent to the control module 22 through the one wireless module 21, so that the control module 22 decides whether to process the real-time audio data collected by the one microphone 10 according to the control signal.

[0037] like Figure 5 As shown, for example, when the number of wireless modules 21 is one and the number of microphones 10 is multiple (more than two), the one wireless module 21 is used to wirelessly communicate with the multiple microphones 10, so that the real-time audio data collected by the multiple microphones 10 can be sent to the control module 22 through the one wireless module 21, so that the control module 22 decides whether to process the real-time audio data collected by the multiple microphones 10 according to the control signal.

[0038] like Figure 6 As shown, for another example, when there are multiple wireless modules 21 and multiple microphones 10, each wireless module 21 is used to wirelessly communicate with one microphone 10, so that the real-time audio data collected by each microphone 10 can be sent to the control module 22 through a wireless module 21 corresponding to the communication connection, so that the control module 22 decides whether to process the real-time audio data collected by multiple microphones 10 according to the control signal.

[0039] like Figure 7 As shown, for another example, when there are multiple wireless modules 21 and multiple microphones 10, there is at least one wireless module 21 for wireless communication with two or more microphones 10, so that the real-time audio data collected by each microphone 10 can be sent to the control module 22 through a wireless module 21 corresponding to the communication connection, so that the control module 22 decides whether to process the real-time audio data collected by multiple microphones 10 according to the control signal.

[0040] like Figure 4-Figure 7 As shown, when the sound card 20 is used to wirelessly communicate with multiple microphones 10, the sound card 20 may include only one wireless module 21, in which case the sound card 20 wirelessly communicates with multiple microphones 10 through the one wireless module 21, or the sound card 20 may include multiple wireless modules 21, in which case the sound card 20 wirelessly communicates with multiple microphones 10 through the multiple wireless modules 21.

[0041] Each wireless module 21 can also send the audio data received from the control module 22 to at least one microphone 10 for corresponding communication, so that each microphone 10 can selectively monitor the audio data of the other microphones 10 .

[0042] The audio data includes real-time audio data and / or processed audio data. The real-time audio data collected by the microphone 10 is still real-time audio data if it is not processed by the control module 22. The real-time audio data collected by the microphone 10 is processed by the control module 22 to obtain processed audio data.

[0043] The real-time audio data collected by all microphones 10 will be sent to the control module 22 through the wireless modules 21 of their corresponding communication connections. The control module 22 will determine whether to process the received real-time audio data based on the control signal. The real-time audio data that has not been processed by the control module 22 and / or the processed audio data obtained after processing by the control module 22 will be sent from the end side where the control module 22 is located to the end side where the microphone 10 is located through the wireless module 21 to realize the monitoring function.

[0044] Each microphone 10 can monitor audio data from other microphones 10 that are communicatively connected to the same wireless module 21 with which it establishes wireless communication, and each microphone 10 can also monitor audio data from other microphones 10 that are communicatively connected to other wireless modules 21 with which it does not establish wireless communication.

[0045] The user can generate a corresponding control signal (specifically, a second control signal different from the above-mentioned first control signal) by operating the input module 24 of the sound card 20 according to actual needs, so that each microphone 10 can selectively monitor the audio data of the other microphones 10. It should be noted that selective monitoring includes the selection of real-time audio data and processed audio data, and also includes the selection of the amount of audio data to be monitored. For example, with respect to the selection of real-time audio data and processed audio data, the user can generate a control signal (specifically, one of the above-mentioned second control signals) by operating the input module 24 of the sound card 20 according to actual needs, and the control module 22 determines whether the microphone 10 chooses to monitor the real-time audio data alone, the processed audio data alone, or the real-time audio data and the processed audio data at the same time based on the control signal. For another example, with regard to the selection of the amount of audio data to be monitored, the user can also generate another control signal (another one of the above-mentioned second control signals) by operating the input module 24 of the sound card 20 according to actual needs. The control module 22 then determines, based on the other control signal, whether the microphone 10 chooses to monitor the audio data of one of the remaining microphones 10 alone, or to monitor the audio data of multiple remaining microphones 10 at the same time.

[0046] It should be noted that each microphone 10 can also monitor the real-time audio data collected by itself. At this time, the microphone core of each microphone 10 sends the collected real-time audio data to the main control module of the microphone 10. The main control module of the wireless microphone 10a directly sends the real-time audio data to the monitoring device 30 connected to it for communication, and the main control module of the wireless headset 10b sends the real-time audio data to the speaker of the wireless headset 10b. Each microphone 10 can also monitor the processed audio data obtained after the real-time audio data collected by itself is processed by the control module 22. At this time, the microphone core of each microphone 10 sends the collected real-time audio data to the control module 22 through the corresponding communication wireless module 21. The control module 22 processes the real-time audio data to obtain processed audio data. The control module 22 then sends the processed audio data to the receiving module of the microphone 10 through the corresponding wireless module 21. The receiving module of the microphone 10 sends the processed audio data to the main control module of the microphone 10. The main control module of the wireless microphone 10a sends the processed audio data to the monitoring device 30 connected to it for communication, and the main control module of the wireless headset 10b sends the processed audio data to the speaker of the wireless headset 10b.

[0047] By designing wireless modules 21 to communicate wirelessly with at least one microphone 10, each wireless module 21 can transmit real-time audio data collected by the corresponding microphone 10 to the control module 22. This allows the control module 22 to process the real-time audio data collected by the microphone 10, resulting in professional-grade sound effects. By designing wireless modules 21 to communicate wirelessly with at least one microphone 10, the range and distance of use of the microphone 10 connected to the wireless module 21 are more flexible than when the sound card 20 is connected to the microphone 10 through a wired connection. This frees the user from the constraints of wires, eliminating the need to worry about the range of use being limited by wire length. When the sound card 20 is communicating wirelessly with multiple microphones 10, each wireless module 21 can also transmit the audio data received from the control module 22 to the corresponding microphone 10, allowing each microphone 10 to selectively monitor the audio data of the remaining microphones 10. This allows users to receive real-time feedback to ensure voice quality and effectively enhance the interactive experience.

[0048] like Figure 8 and Figure 9As shown, each wireless module 21 has multiple audio channels. Some of the audio channels serve as receiving channels, each receiving channel is used to receive real-time audio data collected by a microphone 10 and send the real-time audio data to the control module 22; the remaining audio channels serve as transmitting channels, each transmitting channel is used to receive audio data from a microphone 10 output by the control module 22 and send the audio data to at least one microphone 10 for corresponding communication.

[0049] Among them, for each wireless module 21, the number of audio channels can be two, three, four, five, six or more; when the sound card 20 includes multiple wireless modules 21, for multiple wireless modules 21, the number of audio channels possessed by the multiple wireless modules 21 can be the same or different. It can be understood that the number of audio channels is related to the bandwidth of the wireless module 21. For example, when the wireless module 21 and the microphone 10 communicate via a 2.4G wireless communication protocol, the wireless module 21 can have four audio channels. Each receiving channel is used to receive real-time audio data collected by a microphone 10, which can effectively avoid interference between real-time audio data collected by different microphones 10. Each sending channel is used to send audio data from a microphone 10, which can effectively avoid interference between audio data from different microphones 10.

[0050] By designing multiple audio channels, some of the audio channels are used as receiving channels to receive real-time audio data collected by a microphone 10 and send the real-time audio data to the control module 22, so as to realize the effective transmission of real-time audio data from the end side where the microphone 10 is located to the end side where the control module 22 is located, so that the control module 22 processes the real-time audio data according to the control signal to obtain processed audio data, so that users can enjoy professional-level sound card sound effects, and the remaining audio channels are used as sending channels to receive the audio data of the microphone 10 output by the control module 22, and send the audio data to the corresponding communication microphone 10 to realize real-time monitoring.

[0051] Specifically, if Figure 8 As shown, there are four wireless modules 21, which are used for wireless communication with four microphones 10 in a one-to-one correspondence. Each wireless module 21 has four audio channels, and one of the audio channels is used as a receiving channel to receive real-time audio data collected by a corresponding microphone 10 and send the real-time audio data to the control module 22. The remaining three audio channels are used as sending channels to receive audio data from the remaining three microphones 10 in a one-to-one correspondence.

[0052] For example, the four wireless modules 21 include a first wireless module, a second wireless module, a third wireless module, and a fourth wireless module, and the four microphones 10 include a first microphone 10 that wirelessly communicates with the first wireless module, a second microphone 10 that wirelessly communicates with the second wireless module, a third microphone 10 that wirelessly communicates with the third wireless module, and a fourth microphone 10 that wirelessly communicates with the fourth wireless module. One of the audio channels of the first wireless module serves as a receiving channel for receiving real-time audio data from the first microphone 10 and sending the real-time audio data of the first microphone 10 to the control module 22. The control module 22 can then determine whether to process the real-time audio data of the first microphone 10 based on a control signal. The remaining three audio channels of the first wireless module serve as transmitting channels for receiving audio data from the second microphone 10, the third microphone 10, and the fourth microphone 10, one-to-one. When it is necessary to monitor the audio data of the second microphone 10, the control module 22 can send the audio data of the second microphone 10 to the first microphone 10 through one of its sending channels according to the control signal, so as to realize the real-time monitoring of the audio data of the second microphone 10 by the first microphone 10; when it is necessary to monitor the audio data of the third microphone 10, the control module 22 can send the audio data of the third microphone 10 to the first microphone 10 through one of its sending channels according to the control signal, so as to realize the real-time monitoring of the audio data of the third microphone 10 by the first microphone 10; when it is necessary to monitor the audio data of the fourth microphone 10, the control module 22 can send the audio data of the fourth microphone 10 to the first microphone 10 through one of its sending channels according to the control signal. The control module 22 may transmit the audio data of the second microphone 10, the third microphone 10, and the fourth microphone 10 to the first microphone 10 through one of the transmission channels, so as to enable the first microphone 10 to monitor the audio data of the fourth microphone 10 in real time; when it is necessary to monitor multiple of the audio data of the second microphone 10, the audio data of the third microphone 10, and the audio data of the fourth microphone 10, the control module 22 may transmit multiple of the audio data of the second microphone 10, the audio data of the third microphone 10, and the audio data of the fourth microphone 10 to the first microphone 10 through the multiple transmission channels in a one-to-one correspondence according to the control signal, so as to enable the first microphone 10 to monitor multiple of the audio data of the second microphone 10, the audio data of the third microphone 10, and the audio data of the fourth microphone 10 in real time. The second wireless module, the third wireless module, and the fourth wireless module are similar and will not be described in detail here.

[0053] Specifically, if Figure 9As shown, there are four wireless modules 21 and four microphones 10, and each wireless module 21 is used to wirelessly communicate with two microphones 10. Each wireless module 21 has four audio channels, two of which serve as receiving channels for correspondingly receiving real-time audio data collected by the two corresponding microphones 10 and sending the real-time audio data to the control module 22, and the remaining two audio channels serve as sending channels for correspondingly receiving audio data from the remaining two microphones 10.

[0054] For example, the four wireless modules 21 include a first wireless module, a second wireless module, a third wireless module, and a fourth wireless module. The four microphones 10 include a first microphone 10 and a second microphone 10 in wireless communication with the first wireless module, a second microphone 10 and a third microphone 10 in wireless communication with the second wireless module, a third microphone 10 and a fourth microphone 10 in wireless communication with the third wireless module, and a fourth microphone 10 and the first microphone 10 in wireless communication with the fourth wireless module. Two of the audio channels of the first wireless module serve as receiving channels for receiving real-time audio data from the first microphone 10 and the second microphone 10 in a one-to-one correspondence, and sending the real-time audio data of the first microphone 10 and the second microphone 10 to the control module 22. The control module 22 can then determine whether to process the real-time audio data of the first microphone 10 and / or the real-time audio data of the second microphone 10 based on the control signal. The remaining two audio channels of the first wireless module serve as transmitting channels for receiving audio data from the third microphone 10 and the fourth microphone 10 in a one-to-one correspondence. When it is necessary to monitor the audio data of the third microphone 10, the control module 22 can send the audio data of the third microphone 10 to the first microphone 10 and / or the second microphone 10 through one of its transmission channels according to the control signal, so as to enable the first microphone 10 and / or the second microphone 10 to monitor the audio data of the third microphone 10 in real time; when it is necessary to monitor the audio data of the fourth microphone 10, the control module 22 can send the audio data of the fourth microphone 10 to the first microphone 10 and / or the second microphone 10 through one of its transmission channels according to the control signal, so as to enable the first microphone 10 and / or the second microphone 10 to monitor the audio data of the fourth microphone 10 in real time; when it is necessary to monitor the audio data of the third microphone 10 and the audio data of the fourth microphone 10, the control module 22 can send the audio data of the third microphone 10 and the audio data of the fourth microphone 10 to the first microphone 10 and / or the second microphone 10 through two transmission channels in a one-to-one correspondence according to the control signal, so as to enable the first microphone 10 and / or the second microphone 10 to monitor the audio data of the third microphone 10 and the audio data of the fourth microphone 10 in real time. The second wireless module, the third wireless module and the fourth wireless module are similar and will not be described in detail here.

[0055] like Figure 10 As shown, the sound card 20 also includes a USB-Device interface 23 disposed in the shell and electrically connected to the control module 22. The USB-Device interface 23 is used to connect to the USB host 40 so that the sound card 20 can receive power and / or data from the USB host 40, and enable the sound card 20 to send processed audio data to the USB host 40.

[0056] The USB host 40 may be, but is not limited to, a terminal such as a tablet computer or a desktop computer. The USB-Device interface 23 is a USB Type-A interface, a USB Type-B interface, or a USB Type-C interface. It should be noted that the number of USB-Device interfaces 23 may be one or more, and when there are multiple USB-Device interfaces 23, the types of the multiple USB-Device interfaces 23 may be the same or different.

[0057] The sound card 20 is provided with the USB-Device interface 23, and the type of the USB-Device interface 23 is one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface. It can be connected to a corresponding USB host 40 having one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface, so that the USB host 40 can power the sound card 20 or interact with the USB host 40 for data, and can also send the processed audio data obtained after processing by the control module 22 of the sound card 20 to the USB host 40, so that the USB host 40 such as a computer can perform live broadcast and other operations according to the processed audio data.

[0058] like Figure 10 As shown, the sound card 20 also includes an input module 24 arranged in the shell and electrically connected to the control module 22. The input module 24 is used to generate different control signals (specifically, a third control signal different from the above-mentioned first control signal and the above-mentioned second control signal) under the user's operation, and the control module 22 implements different functions of the sound card 20 according to different control signals.

[0059] Among them, the functions include at least one of the power on and off function, volume adjustment function, noise reduction, reverberation and voice change processing function. The input module 24 can be, but is not limited to, a knob, a button or a touch screen set on the shell. For example, the user can generate a control signal (one of the above-mentioned third control signals) by turning the knob according to actual needs, and the control module 22 controls the sound card 20 according to the control signal to achieve the volume adjustment function; for another example, the user can generate another control signal (another of the above-mentioned third control signals) by pressing the button according to actual needs, and the control module 22 controls the sound card 20 according to the other control signal to achieve the power on and off function; for another example, the user can generate another control signal (another of the above-mentioned third control signals) by manipulating the touch screen according to actual needs, and the control module 22 controls the sound card 20 according to the other control signal to achieve the noise reduction, reverberation and voice change processing functions.

[0060] like Figure 11 As shown, the control module 22 includes an audio processing unit 221 and a main control unit 222. The audio processing unit 221 is electrically connected to at least one wireless module 21 and is used to process the real-time audio data collected by all microphones 10 and obtain a processed audio stream. The audio processing unit 221 is also used to perform reverberation processing, noise reduction processing, or voice modification processing on the obtained processed audio stream to obtain processed audio data. The main control unit 222 is electrically connected to the audio processing unit 221 to control the operation of the audio processing unit 221.

[0061] Specifically, the audio processing unit 221 includes an analog-to-digital converter 221a and an asynchronous sampling rate converter 221b. The analog-to-digital converter 221a is electrically connected to at least one wireless module 21 and is used to convert the real-time audio data collected by all microphones 10 into a PCM (Pulse Code Modulation) audio stream. The asynchronous sampling rate converter 221b is electrically connected to the analog-to-digital converter 221a and is used to convert the sampling rate of the PCM audio stream.

[0062] Specifically, the audio processing unit 221 further includes a digital signal processor 221c, which is electrically connected to the asynchronous sampling rate converter 221b. The digital signal processor 221c is used to perform reverberation processing, noise reduction processing, or voice change processing on the PCM audio stream to obtain processed audio data.

[0063] Among them, the above-mentioned processed audio stream includes a PCM audio stream. Reverb processing is an audio processing technology used to simulate the reflection and diffusion effects of sound in different spatial environments. It creates sound effects similar to those in real spaces (such as rooms, halls, churches, etc.) by adding a series of delayed and attenuated reflected sounds to the PCM audio stream. Noise reduction is an audio processing technology that aims to reduce or eliminate unnecessary noise components in the PCM audio stream, thereby improving the clarity and quality of the processed audio data. Voice pitch modification (Voice pitch modification or voice transformation) is an audio processing technology used to change the pitch, timbre or other sound characteristics in the PCM audio stream to achieve a specific effect. The specific implementation methods of reverberation processing, noise reduction processing and voice transformation processing are not described here in detail, and can be directly implemented by using the reverberation processing, noise reduction processing and voice transformation processing technologies in the relevant technologies.

[0064] Under the control of the main control unit 222, the analog-to-digital converter 221a of the audio processing unit 221 converts the real-time audio data collected by all microphones 10 into a PCM audio stream, the asynchronous sampling rate converter 221b of the audio processing unit 221 converts the sampling rate of the PCM audio stream, and the digital signal processor 221c of the audio processing unit 221 performs reverberation processing, noise reduction processing, or voice change processing on the PCM audio stream so that the audio processing unit 221 obtains the processed audio data, thereby completing the processing of the real-time audio data collected by the microphone 10 to achieve professional-level sound card sound effects.
