[0002] With the development of wireless communication technology, audio data can now be transmitted between microphone devices and audio processing devices via wireless communication. Currently, microphone devices only support a single transmission method, transmitting the acquired audio data to a single audio processing device. However, with technological advancements, microphone devices that can only transmit single-channel audio can no longer meet the needs of many business scenarios. The audio data acquired by microphone devices cannot undergo multi-dimensional synchronous processing, resulting in low audio data processing efficiency. Summary of the Invention

[0003] Therefore, it is necessary to provide an audio data processing method, apparatus, device, storage medium, and program product that can improve the efficiency of audio data processing in response to the above-mentioned technical problems.

[0004] In a first aspect, this application provides an audio data processing method applied to a microphone device, the method comprising:

[0005] Collect audio data to be processed;

[0006] Select at least two target transmission channels with independent frequency bands from a plurality of pre-defined candidate transmission channels;

[0007] For each selected target transmission channel, the audio data is transmitted to the audio processing device corresponding to the target transmission channel using the transmission method corresponding to the target transmission channel, so that the audio processing device can process the audio data; wherein, each target transmission channel corresponds to a transmission method and an audio processing device.

[0008] In one embodiment, selecting at least two target transmission channels with mutually independent frequency bands from a preset plurality of candidate transmission channels includes:

[0009] From a plurality of preset candidate transmission channels, a first target transmission channel and a second target transmission channel with independent frequency bands are selected; the audio processing device corresponding to the first target transmission channel is a speaker device, and the audio processing device corresponding to the second target transmission channel is an interactive smart flat panel device;

[0010] For each selected target transmission channel, the audio data is transmitted to the audio processing device corresponding to the target transmission channel using the transmission mode corresponding to the target transmission channel, so that the audio processing device processes the audio data, including:

[0011] In the first target transmission channel, the first transmission method corresponding to the first target transmission channel is used to transmit the audio data to the speaker device, so that the speaker device can perform local amplification based on the audio data;

[0012] The audio data is transmitted to the interactive smart flat panel device using the second transmission method corresponding to the second target transmission channel, so that the large model in the interactive smart flat panel device can analyze the audio data and generate a target report.

[0013] In the above embodiments, audio data is transmitted to the speaker device using a first transmission method corresponding to the first target transmission channel, enabling the speaker device to perform local amplification based on the audio data. Simultaneously, audio data is transmitted to the interactive smart flat panel device using a second transmission method corresponding to the second target transmission channel, allowing the large model in the interactive smart flat panel device to analyze the audio data and generate a target report. Thus, while the speaker device performs local amplification based on the audio data, the interactive smart flat panel device can also simultaneously analyze the audio data and generate a target report, improving the processing efficiency of the audio data.

[0014] In one embodiment, selecting a first target transmission channel and a second target transmission channel from a preset plurality of candidate transmission channels includes:

[0015] From the multiple first candidate transmission channels corresponding to the first transmission mode, the first candidate transmission channel with the best performance is selected as the first target transmission channel;

[0016] From the multiple second candidate transmission channels corresponding to the second transmission mode, select a second target transmission channel that is different from the first target transmission channel.

[0017] In the above embodiments, by selecting the first candidate transmission channel with the best performance from among multiple first candidate transmission channels corresponding to the first transmission mode as the first target transmission channel, the transmission efficiency of audio data can be improved. Simultaneously, by selecting a second target transmission channel different from the first target transmission channel from among multiple second candidate transmission channels corresponding to the second transmission mode, interference between the first and second transmission modes during audio data transmission can be avoided, further improving the processing efficiency of audio data.

[0018] In one embodiment, selecting the first candidate transmission channel with the best performance from a plurality of first candidate transmission channels corresponding to the first transmission mode as the first target transmission channel includes:

[0019] Obtain channel evaluation parameters for multiple first candidate transmission channels corresponding to the first transmission mode, and determine the first interference score value of the multiple first candidate transmission channels based on the channel evaluation parameters.

[0020] The total frequency band occupied by the plurality of first candidate transmission channels is divided into a plurality of sub-frequency bands; each sub-frequency band contains at least one first candidate transmission channel.

[0021] For each sub-frequency band, from each first candidate transmission channel under the sub-frequency band, find the co-channel interference channel that is interfered with by the interference source of the sub-frequency band at the same frequency, and the adjacent channel interference channel that is interfered with by the interference source of the sub-frequency band at the adjacent frequency.

[0022] Based on the channel evaluation parameters of the co-channel interference channel, determine the second interference score value of the co-channel interference channel and the third interference score value of the adjacent channel interference channel.

[0023] Based on the first interference score, the second interference score, and the third interference score of the plurality of first candidate transmission channels, a comprehensive interference score is determined for the plurality of first candidate transmission channels.

[0024] From the plurality of first candidate transmission channels, the first candidate transmission channel with the lowest comprehensive interference score is selected as the first target transmission channel.

[0025] In the above embodiments, the comprehensive interference score of multiple first candidate transmission channels is determined by the first interference score, the second interference score, and the third interference score of multiple first candidate transmission channels. The first candidate transmission channel with the lowest comprehensive interference score is selected as the first target transmission channel from among the multiple first candidate transmission channels. This can improve the accuracy of selecting the first candidate transmission channel with the best performance, thereby further improving the transmission efficiency of audio data.

[0026] In one embodiment, the channel evaluation parameters include noise level and busy time; the first interference score is determined based on the busy time; the second interference score is determined based on the noise level and busy time of the co-channel interference; and the third interference score is determined based on the noise level and busy time of the adjacent channel interference.

[0027] In the above embodiments, by determining the first interference score based on the busy time, the second interference score based on the noise level and busy time of the co-channel interference channel, and the third interference score based on the noise level and busy time of the adjacent channel interference channel, the accuracy of selecting the first candidate transmission channel with the best performance can be further improved.

[0028] In one embodiment, the method further includes:

[0029] In response to a triggering operation on an interactive component on the microphone device, a control command is generated;

[0030] The control command is transmitted to the interactive smart tablet device using the second transmission method corresponding to the second target transmission channel, so that the interactive smart tablet device executes the control operation indicated by the control command.

[0031] In the above embodiments, by using the second transmission method corresponding to the second target transmission channel in the second target transmission channel, the control command of the microphone device is transmitted to the interactive smart tablet device, so that the interactive smart tablet device executes the control operation indicated by the control command, thereby improving the interaction efficiency of the interactive smart tablet device.

[0032] Secondly, this application provides an audio data processing apparatus for use in a microphone device, the apparatus comprising:

[0034] The selection module is used to select at least two target transmission channels with mutually independent frequency bands from a plurality of preset candidate transmission channels;

[0035] The transmission module is used to transmit the audio data to the audio processing device corresponding to the target transmission channel for each selected target transmission channel using the transmission mode corresponding to the target transmission channel, so that the audio processing device can process the audio data; wherein, each target transmission channel corresponds to a transmission mode and an audio processing device.

[0036] Thirdly, this application provides a microphone device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps in the various method embodiments of this application.

[0037] Fourthly, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps in the various method embodiments of this application.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] In traditional technology, microphone devices only support transmitting captured audio data to a single audio processing device via a single transmission method. However, with technological advancements, microphone devices that can only transmit single-channel audio can no longer meet the needs of many business scenarios. The audio data captured by microphone devices cannot be processed synchronously in multiple dimensions, resulting in low audio data processing efficiency.

[0047] However, this application acquires audio data to be processed using a microphone device; selects at least two target transmission channels with independent frequency bands from a plurality of preset candidate transmission channels; and for each selected target transmission channel, transmits the audio data to the corresponding audio processing device using the transmission method corresponding to the target transmission channel, so that the audio processing device can process the audio data; wherein, each target transmission channel corresponds to a transmission method and an audio processing device. Compared with the traditional audio data processing method of single-channel transmission, this application improves the audio data processing efficiency by transmitting the audio data acquired by the microphone device to different audio processing devices in multiple channels, so that different audio processing devices can perform multi-dimensional synchronous processing of the audio data.

[0048] The audio data processing method provided in this application can be applied to, for example... Figure 1 In the application environment shown, the microphone device 102 can acquire audio data to be processed and select at least two target transmission channels with independent frequency bands from a plurality of preset candidate transmission channels. For each selected target transmission channel, the microphone device 102 can use the transmission mode corresponding to the target transmission channel to transmit the audio data to the audio processing device 104 corresponding to the target transmission channel, so that the audio processing device 104 can process the audio data; wherein, each target transmission channel corresponds to a transmission mode and an audio processing device 104.

[0049] In one embodiment, such as Figure 2 As shown, an audio data processing method is provided, applied to a microphone device, including the following steps:

[0050] Step 202: Collect the audio data to be processed.

[0051] In one embodiment, the microphone device can collect sounds in the environment to obtain audio data to be processed. For example, in a teaching scenario, a teacher holds a microphone device while lecturing in the classroom, and the microphone device can collect the sounds emitted by the teacher during the lecture to obtain audio data to be processed.

[0052] Step 204: Select at least two target transmission channels with independent frequency bands from a set of multiple candidate transmission channels.

[0053] In one embodiment, the microphone device can determine multiple candidate transmission channels corresponding to different transmission methods. It is understood that each transmission method corresponds to at least one candidate transmission channel, and different candidate transmission channels under the same transmission method correspond to different frequency bands. The frequency bands corresponding to the multiple candidate transmission channels may overlap. For example, transmission method 1 corresponds to n candidate transmission channels in different frequency bands, and transmission method 2 corresponds to m candidate transmission channels in different frequency bands. There may be frequency band overlap among the n candidate channels corresponding to transmission method 1 and the m candidate channels corresponding to transmission method 2. Furthermore, the microphone device can select at least two transmission channels with independent frequency bands from the multiple candidate channels corresponding to each transmission method. Each selected transmission channel corresponds to a different transmission method.

[0054] In one embodiment, the transmission method may include BLE (Bluetooth Low Energy) transmission, WIFI (mobile hotspot) transmission, and UHF (specific frequency band) transmission in the field of wireless communication.

[0055] Step 206: For each selected target transmission channel, the audio data is transmitted to the audio processing device corresponding to the target transmission channel using the transmission method corresponding to the target transmission channel, so that the audio processing device can process the audio data; wherein, each transmission channel corresponds to a transmission method and an audio processing device.

[0056] It is understandable that different target transmission channels correspond to different transmission methods and different audio processing devices.

[0057] In one embodiment, the microphone device can select a first target transmission channel and a second target transmission channel from a plurality of preset candidate transmission channels. The microphone device can transmit audio data to an audio processing device corresponding to the first target transmission channel using a first transmission method corresponding to the first target transmission channel, so that the audio processing device corresponding to the first target transmission channel can process the audio data. Similarly, the microphone device can transmit audio data to an audio processing device corresponding to the second target transmission channel using a second transmission method corresponding to the second target transmission channel, so that the audio processing device corresponding to the second target transmission channel can process the audio data.

[0058] It should be noted that the microphone device can also select more than three target transmission channels from a number of preset candidate transmission channels. Different target transmission channels correspond to different transmission methods and different audio processing devices.

[0059] In the aforementioned audio data processing method, audio data to be processed is acquired using a microphone device; at least two target transmission channels with independent frequency bands are selected from a plurality of preset candidate transmission channels; for each selected target transmission channel, the audio data is transmitted to the corresponding audio processing device using the transmission mode corresponding to the target transmission channel, so that the audio processing device can process the audio data; wherein, each target transmission channel corresponds to a transmission mode and an audio processing device. Compared with traditional audio data processing methods that transmit audio data in a single channel, this application improves the processing efficiency of audio data by transmitting the audio data acquired by the microphone device in multiple channels to different audio processing devices, so that different audio processing devices can perform multi-dimensional synchronous processing of the audio data.

[0060] In one embodiment, selecting at least two target transmission channels with independent frequency bands from a plurality of preset candidate transmission channels includes: selecting a first target transmission channel and a second target transmission channel from the plurality of preset candidate transmission channels; the audio processing device corresponding to the first target transmission channel is a speaker device, and the audio processing device corresponding to the second target transmission channel is an interactive smart flat panel device; for each selected target transmission channel, transmitting audio data to the audio processing device corresponding to the target transmission channel using the transmission method corresponding to the target transmission channel, so that the audio processing device processes the audio data, including: transmitting audio data to the speaker device using a first transmission method corresponding to the first target transmission channel in the first target transmission channel, so that the speaker device performs local amplification based on the audio data; transmitting audio data to the interactive smart flat panel device using a second transmission method corresponding to the second target channel in the second target channel, so that the large model in the interactive smart flat panel device analyzes the audio data and generates a target report.

[0061] In one embodiment, the audio data processing method of this application can be applied to a teaching scenario. Specifically, a teacher uses a handheld microphone device to teach in the classroom. The microphone device can collect the sound emitted by the teacher during the teaching process and obtain audio data to be processed. The microphone device can select a first target transmission channel and a second target transmission channel with independent frequency bands from a plurality of preset candidate transmission channels. The audio processing device corresponding to the first target transmission channel is a speaker device in the classroom, and the audio processing device corresponding to the second target transmission channel is an interactive smart whiteboard device in the classroom. The microphone device can use a first transmission method corresponding to the first target transmission channel to transmit the audio data to the speaker device, so that the speaker device can amplify the audio data locally so that students in the classroom can hear the teacher's voice clearly. At the same time, the microphone device can use a second transmission method corresponding to the second target transmission channel to transmit the audio data to the interactive smart whiteboard device, so that the large model in the interactive smart whiteboard device can analyze the audio data and generate the teacher's teaching report.

[0062] In one embodiment, such as Figure 3 As shown, the first transmission method is BLE transmission, and the second transmission method is Wi-Fi transmission. Specifically, the microphone device can use BLE transmission in the first target transmission channel to transmit audio data to the speaker device, enabling the speaker device to amplify the audio data locally. Simultaneously, the microphone device can use Wi-Fi transmission in the second target transmission channel to transmit audio data to the interactive smart panel device, allowing the large model in the interactive smart panel device to analyze the audio data and generate a target report.

[0063] In the above embodiments, audio data is transmitted to the speaker device using a first transmission method corresponding to the first target transmission channel, enabling the speaker device to perform local amplification based on the audio data. Simultaneously, audio data is transmitted to the interactive smart flat panel device using a second transmission method corresponding to the second target transmission channel, allowing the large model in the interactive smart flat panel device to analyze the audio data and generate a target report. Thus, while the speaker device performs local amplification based on the audio data, the interactive smart flat panel device can also simultaneously analyze the audio data and generate a target report, improving the processing efficiency of the audio data.

[0064] In one embodiment, selecting a first target transmission channel and a second target transmission channel from a plurality of preset candidate transmission channels includes: selecting the first candidate transmission channel with the best performance from a plurality of first candidate transmission channels corresponding to a first transmission mode as the first target transmission channel; and selecting a second target transmission channel that is different from the first target transmission channel from a plurality of second candidate transmission channels corresponding to a second transmission mode.

[0065] In one embodiment, the microphone device can perform interference scoring on multiple first candidate transmission channels corresponding to the first transmission mode, obtaining a comprehensive interference score value for each of the multiple first candidate transmission channels. The microphone device can then select the first candidate transmission channel with the lowest comprehensive interference score value from among the multiple first candidate transmission channels as the first target transmission channel. It can be understood that the first candidate transmission channel with the lowest comprehensive interference score value is the best-performing first candidate transmission channel among the multiple first candidate transmission channels. Furthermore, the microphone device can select a second target transmission channel, different from the first target transmission channel, from among the multiple second candidate transmission channels corresponding to the second transmission mode, to avoid data transmission interference between different transmission modes.

[0066] For example, the first transmission method is Wi-Fi, with 13 candidate transmission channels. The second transmission method is BLE, with 40 candidate transmission channels. Among the 13 candidate channels for Wi-Fi and the 40 candidate channels for BLE, some may overlap in frequency bands. Therefore, to avoid overlapping transmission channels, the microphone device can select the highest-performing candidate channel from the multiple candidate channels for the first transmission method as the first target transmission channel to improve audio data transmission efficiency. It can also select a different target transmission channel from the multiple candidate channels for the second transmission method to avoid data transmission interference between the different transmission methods.

[0067] In the above embodiments, by selecting the first candidate transmission channel with the best performance from among multiple first candidate transmission channels corresponding to the first transmission mode as the first target transmission channel, the transmission efficiency of audio data can be improved. Simultaneously, by selecting a second target transmission channel different from the first target transmission channel from among multiple second candidate transmission channels corresponding to the second transmission mode, interference between the first and second transmission modes during audio data transmission can be avoided, further improving the processing efficiency of audio data.

[0068] In one embodiment, selecting the first candidate transmission channel with the best performance from a plurality of first candidate transmission channels corresponding to a first transmission mode as the first target transmission channel includes: obtaining channel evaluation parameters of the plurality of first candidate transmission channels corresponding to the first transmission mode, and determining a first interference score value of the plurality of first candidate transmission channels based on the channel evaluation parameters; dividing the total frequency band occupied by the plurality of first candidate transmission channels into a plurality of sub-frequency bands; each sub-frequency band contains at least one first candidate transmission channel; for each sub-frequency band, finding, from each first candidate transmission channel in the sub-frequency band, a co-channel interference channel affected by co-channel interference from an interference source in the sub-frequency band, and an adjacent-channel interference channel affected by adjacent-channel interference from an interference source in the sub-frequency band; determining a second interference score value of the co-channel interference channel and a third interference score value of the adjacent-channel interference channel based on the channel evaluation parameters of the co-channel interference channel; determining a comprehensive interference score value of the plurality of first candidate transmission channels based on the first interference score value, the second interference score value, and the third interference score value of the plurality of first candidate transmission channels; and selecting the first candidate transmission channel with the lowest comprehensive interference score value from the plurality of first candidate transmission channels as the first target transmission channel.

[0069] In this scenario, the frequency of a co-channel interference channel is the same as the frequency of the interference source. The frequency of an adjacent-channel interference channel is adjacent to the frequency of the interference source.

[0070] In one embodiment, the microphone device may perform a weighted calculation on the first interference score, the second interference score, and the third interference score of multiple first candidate transmission channels, and use the weighted result as the comprehensive interference score of the multiple first candidate transmission channels.

[0071] In one embodiment, the microphone device may add together the first interference score, the second interference score, and the third interference score of multiple first candidate transmission channels, and use the sum as the comprehensive interference score of the multiple first candidate transmission channels.

[0072] In the above embodiments, the comprehensive interference score of multiple first candidate transmission channels is determined by the first interference score, the second interference score, and the third interference score of multiple first candidate transmission channels. The first candidate transmission channel with the lowest comprehensive interference score is selected as the first target transmission channel from among the multiple first candidate transmission channels. This can improve the accuracy of selecting the first candidate transmission channel with the best performance, thereby further improving the transmission efficiency of audio data.

[0073] In one embodiment, the channel evaluation parameters include noise level and busy time; a first interference score is determined based on the busy time; a second interference score is determined based on the noise level and busy time of the co-channel interference channel; and a third interference score is determined based on the noise level and busy time of the adjacent channel interference channel.

[0074] In one embodiment, the microphone device can set a channel scanning duration. Within this duration, it scans multiple candidate transmission channels corresponding to the first transmission mode repeatedly to obtain the noise level and busy time of each candidate transmission channel. The microphone device can filter the noise level and busy time of the same candidate transmission channel and average the filtered noise level and busy time to obtain an average noise level and average busy time. Based on the average busy time of each candidate transmission channel and a preset weight value, the microphone device can determine a first interference score for the multiple candidate transmission channels. The microphone device can divide the total frequency band occupied by the multiple candidate transmission channels into multiple sub-bands, where each sub-band contains at least one candidate transmission channel. For each sub-band, the microphone device can determine the center frequency and bandwidth of the interference source within that sub-band based on the noise level of the candidate transmission channels, thus determining which frequency band the interference source is located in and how much frequency space it occupies within the sub-band. The microphone device can, based on the center frequency and bandwidth of the interference source, and the noise level and average busy time of the first candidate transmission channels in the sub-band, identify co-channel interference channels affected by co-channel interference from the interference source in the sub-band, and adjacent-channel interference channels affected by adjacent-channel interference from the interference source in the sub-band. The microphone device can determine a second interference score value for the co-channel interference channel and a third interference score value for the adjacent-channel interference channel based on the noise level and average busy time of the co-channel interference channel. The microphone device can determine a comprehensive interference score value for multiple first candidate transmission channels based on the first, second, and third interference score values, and select the first candidate transmission channel with the lowest comprehensive interference score value as the first target transmission channel.

[0075] In the above embodiments, by determining the first interference score based on the busy time, the second interference score based on the noise level and busy time of the co-channel interference channel, and the third interference score based on the noise level and busy time of the adjacent channel interference channel, the accuracy of selecting the first candidate transmission channel with the best performance can be further improved.

[0076] In one embodiment, the method further includes: generating a control command in response to a triggering operation on an interactive component on a microphone device; and transmitting the control command to an interactive smart tablet device using a second transmission method corresponding to the second target transmission channel in a second target transmission channel, so that the interactive smart tablet device executes the control operation indicated by the control command.

[0077] In one embodiment, the interactive component on the microphone device is a page-turning button, and the control command is a page-turning control command. The microphone device can generate a page-turning control command in response to a trigger operation on the page-turning button on the microphone device, and transmit the page-turning control command to the interactive smart flat panel device using the second transmission method corresponding to the second target transmission channel, so that the interactive smart flat panel device can turn pages of the displayed PPT (presentation document).

[0078] In the above embodiments, by using the second transmission method corresponding to the second target transmission channel in the second target transmission channel, the control command of the microphone device is transmitted to the interactive smart tablet device, so that the interactive smart tablet device executes the control operation indicated by the control command, thereby improving the interaction efficiency of the interactive smart tablet device.

[0079] In one embodiment, the method further includes: acquiring microphone status information; transmitting the microphone status information to an interactive smart tablet device using a second transmission method corresponding to the second target transmission channel in the second target transmission channel, so that the interactive smart tablet device can display the microphone status information.

[0080] In one embodiment, microphone status information may include at least one of the following: microphone device on / off status information and remaining battery power information.

[0081] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially, these steps are not necessarily executed in that order. Unless otherwise expressly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the above embodiments may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the sub-steps or stages of other steps.

[0082] In one embodiment, such as Figure 4 As shown, an audio data processing device 400 is provided, applied to a microphone device, the device specifically including:

[0085] The transmission module 406 is used to transmit audio data to the audio processing device corresponding to each selected target transmission channel using the transmission method corresponding to the target transmission channel, so that the audio processing device can process the audio data; wherein, each target transmission channel corresponds to a transmission method and an audio processing device.

[0086] In one embodiment, the selection module 404 is further configured to select a first target transmission channel and a second target transmission channel with mutually independent frequency bands from a plurality of preset candidate transmission channels; the audio processing device corresponding to the first target transmission channel is a speaker device, and the audio processing device corresponding to the second target transmission channel is an interactive smart flat panel device; the transmission module 406 is further configured to transmit audio data to the speaker device in the first target transmission channel using a first transmission method corresponding to the first target transmission channel, so that the speaker device can perform local amplification based on the audio data; and transmit audio data to the interactive smart flat panel device in the second target transmission channel using a second transmission method corresponding to the second target transmission channel, so that the large model in the interactive smart flat panel device can analyze the audio data and generate a target report.
