In this embodiment, an audio data processing method will be described by taking an execution subject as a communication terminal. The communication terminal may be any device capable of communication, such as an interphone, a mobile phone, and a telephone watch. The audio player can be a Bluetooth earphone, a Bluetooth loudspeaker box and other devices with an audio playing function. In some disclosed embodiments, a communication terminal includes a master control unit and a first bluetooth unit. The main control unit and the first Bluetooth unit are in signal communication and control through a communication interface. The communication interface may be an SPI (Serial Peripheral Interface ) interface, UART (Universal Asynchronous Receiver and Transmitter, asynchronous transceiver interface) interface, USB interface, IIC (Inter-Integrated Circuit, integrated circuit bus interface) interface, or the like. The first bluetooth unit may be configured to establish a communication connection with the audio playback device and may also be configured to perform denoising.

The accessory information may specifically include at least one of a device identification and a firmware version number. By way of example, the device identification of the communication terminal may be a device model of the communication terminal and the device identification of the audio player may be a model of the audio player.
The first device information of the communication terminal is stored in a memory space of the communication terminal. The communication terminal may acquire the second device information of the audio player by sending a request instruction to the audio player through a communication connection with the audio player, so that the audio player sends the second device information to the communication terminal after receiving the request instruction.
Step S12: and determining a target denoising parameter based on the first device information and the second device information.
The method for determining the target denoising parameter based on the first device information and the second device information may be to match the first device information and the second device information with each piece of first device information and each piece of second device in the pre-established parameter configuration information, so as to obtain the target denoising parameter.
Step S13: and denoising the audio data to be processed by using the target denoising parameters to obtain target audio data, wherein the audio data to be processed is the audio data received by the communication terminal, and the target audio data is provided for an audio player to play.
The audio data to be processed may be audio data received by the communication terminal from other communication terminals. Illustratively, the communication terminal and the other communication terminals receive voice data from the other communication terminals as audio data to be processed when making a voice or video call.
According to the scheme, the target denoising parameters are determined according to the equipment information of the communication terminal and the audio player, and then the denoising processing of the audio data to be processed is realized by using the target denoising parameters.
In some disclosed embodiments, the denoising process includes at least one of an echo cancellation process and a denoising process. Wherein the echo cancellation process is used to reduce echo in the audio data. The noise reduction process is used to reduce noise in the audio data. The noise in the audio data may be gaussian noise generated in the data transmission process, or any sound not belonging to the target object may be used as noise, the target object may be a human body, and the sound not belonging to the target object may be sound such as automobile whistle. In some application scenarios, the denoising process includes an echo cancellation process. In some application scenarios, the denoising process includes a denoising process. In some application scenarios, the denoising process includes an echo cancellation process and a denoising process. The target denoising parameters corresponding to the echo cancellation processing are target echo cancellation parameters, and the target denoising parameters corresponding to the noise reduction processing are target noise reduction parameters. The target echo cancellation parameters are used for realizing echo cancellation processing of the audio data to be processed, and the target noise reduction parameters are used for realizing noise reduction processing of the audio data to be processed.
Wherein the communication connection between the communication terminal and the audio player may be a bluetooth connection. I.e. the bluetooth of the communication terminal establishes a connection with the bluetooth of the audio player. And then communication between the two is realized through a Bluetooth custom protocol. Specifically, the communication may be performed by AT commands, SPP protocol data, or the like.
In some disclosed embodiments, the step S12 may include the steps of:
and judging whether the audio player has started the denoising function. Illustratively, the communication terminal determines whether the audio player has turned on the denoising function. Wherein, the audio player can perform denoising processing on the audio data received from the communication terminal under the condition that the denoising function is started. In the case where the audio player does not turn on the denoising function, the denoising process cannot be performed on the audio data received from the communication terminal. The on and off of the denoising function of the audio player can be controlled by a user in a menu of the audio player or a function switch button is arranged on the audio player, and the user can turn on or off the denoising function of the audio player by pressing or clicking the switch button. Alternatively, the on and off of the denoising function of the audio player may also be controlled by the communication terminal, and the communication terminal sends a control instruction to the audio player, for example, the instruction being for instructing the audio player to turn on or off the denoising function. The communication terminal may send the control instruction to the audio player after receiving a preset operation of the communication terminal by the user. The mode of the communication terminal judging whether the audio player starts the denoising function may be to send a query instruction to the audio player, so that the audio player sends a query result to the communication terminal after receiving the query instruction. The query result includes whether the audio player has or has not turned on the denoising function.
As described above, the denoising process includes the echo cancellation process and the denoising process. Determining whether the audio player has turned on the denoising function includes determining whether the audio player has turned on the echo cancellation function, and determining whether the audio player has turned on the denoising function. The determining whether the audio player has turned on the echo cancellation function and the determining whether the audio player has turned on the noise reduction function may be separately performed and the order of execution of the two may not be limited in the case of separate execution, or the two determining processes may be performed in combination, for example, using a query instruction query. And executing the following steps related to echo cancellation according to the judgment result of whether the audio player starts the echo cancellation function. And executing the following steps related to the noise reduction function according to the judgment result of whether the audio player has started the noise reduction function. The two judging results are mutually independent and cannot influence each other.
In response to the audio player having turned on the denoising function, a target denoising parameter is determined for the audio player based on the first device information and the second device information. By determining the target denoising parameters for the audio player, the audio player is enabled to denoise audio data received from the communication terminal using the target denoising parameters. In some application scenarios, a target echo cancellation parameter is determined for an audio player based on first device information and second device information in response to the audio player having turned on an echo cancellation function. In some application scenarios, a target noise reduction parameter is determined for an audio player based on first device information and second device information in response to the audio player having turned on a noise reduction function.
In some application scenarios, the communication terminal may further send the first device information to the audio player when the audio player has turned on the denoising function, so that the audio player determines the target denoising parameter of the audio player based on the received first device information and the second device information thereof. For example, in the case that the audio player has turned on the echo cancellation function, the communication terminal may further transmit the first device information to the audio player, so that the audio player determines the target echo cancellation parameter of the audio player based on the received first device information and the own second device information. The audio player may store preset parameter configuration information, where the preset parameter configuration information includes a plurality of denoising parameters. Each denoising parameter corresponds to a set of associated device information. Each set of associated device information includes first device information of one communication terminal and second device information of one audio player. The audio player determines denoising parameters corresponding to the first equipment information and the second equipment information from preset parameter configuration information, and takes the denoising parameters as target denoising parameters. The method for determining the target denoising parameter by the audio player from the preset parameter configuration information can be referred to as the following method for determining the target denoising parameter by the communication terminal from the preset parameter configuration information, which is not described in detail herein.
For example, in the case that the audio player has turned on the noise reduction function, the communication terminal may further transmit the first device information to the audio player so that the audio player determines the target noise reduction parameter of the audio player based on the received first device information and the own second device information. And, the communication terminal transmits the audio data to be processed to the audio player after receiving a signal for indicating completion of configuration of the audio player, so that the audio player performs denoising processing on the audio data to be processed based on the target denoising parameter, and plays the denoised audio data.
And determining target denoising parameters for the communication terminal based on the first equipment information and the second equipment information in response to the fact that the denoising function of the audio player is not started. By determining the target denoising parameters for the communication terminal, the communication terminal is enabled to denoise audio data received from other communication terminals using the target denoising parameters. In some application scenarios, in response to the audio player not turning on the echo cancellation function, a target echo cancellation parameter is determined for the communication terminal based on the first device information and the second device information. In some application scenarios, in response to the audio player not turning on the noise reduction function, a target noise reduction parameter is determined for the communication terminal based on the first device information and the second device information.
In some disclosed embodiments, before performing the step of the communication terminal determining whether the audio player has turned on the denoising function, the following steps may be further performed:
and judging whether the audio player supports the denoising function. Illustratively, it is determined whether the audio player supports an echo cancellation function and a noise reduction function. Wherein, the determining whether the audio player supports the echo cancellation function and whether the audio player supports the noise reduction function may be performed separately and the order of execution is not limited in the case of separate execution, or the two determining processes may be performed in combination. Because some audio players may not have a denoising function, there is no need to determine whether they have already turned on the denoising function and the target denoising parameters. The mode of determining whether the audio player supports the denoising function may be determined according to the second device information of the audio player. For example, according to the firmware version number of the audio player, the functions of the audio player under the firmware version number can be queried through the firmware version number.
In response to the audio player supporting the denoising function, the step of determining whether the audio player has turned on the denoising function is performed. In some application scenarios, in response to the audio player supporting the echo cancellation function, the step of determining whether the audio player has turned on the echo cancellation function is performed. In some application scenarios, in response to the audio player supporting the noise reduction function, the step of determining whether the audio player has turned on the noise reduction function is performed.
In response to the audio player not supporting the denoising function, the step of determining whether the audio player has turned on the denoising function is not performed, and the step of determining a target denoising parameter for the communication terminal based on the first device information and the second device is performed. In some application scenarios, in response to the audio player not supporting the echo cancellation function, the step of determining whether the audio player has turned on the echo cancellation function is not performed, and the step of determining a target echo cancellation parameter for the communication terminal based on the first device information and the second device information is performed. In some application scenarios, in response to the audio player not supporting the noise reduction function, the step of determining whether the audio player has turned on the noise reduction function is not performed, and the step of determining a target noise reduction parameter for the communication terminal based on the first device information and the second device is performed.
In some disclosed embodiments, the audio data processing method further comprises the steps of:
and enabling the communication terminal to start or keep the denoising function on in response to the audio player not supporting the denoising function or the audio player not starting the denoising function. In some application scenarios, in response to the audio player not supporting the denoising function, the communication terminal turns on the denoising function, or if the communication terminal has turned on the denoising function, the denoising function is kept on. The communication terminal can be used for denoising the audio data received from other communication terminals under the condition of starting the denoising function. In some application scenarios, the communication terminal turns on the denoising function or keeps the denoising function on in response to the audio player not turning on the denoising function.
In response to the audio player having turned on the denoising function, the communication terminal is turned off or remains turned off the denoising function. In some application scenarios, because the audio player has already turned on the denoising function, the denoising function can be used for denoising the audio data, if the communication terminal also turns on the denoising function, the denoised audio data is sent to the audio player after the denoising process is performed on the audio data, and the audio player performs the denoising process on the denoised audio data again, and the denoising process is performed on the audio data twice, so that problems such as sound distortion and poor sound quality may be caused.
In some disclosed embodiments, the step S12 may include the steps of:
and determining denoising parameters corresponding to the first equipment information and the second equipment information from preset parameter configuration information, and taking the denoising parameters as target denoising parameters.
The preset parameter configuration information comprises a plurality of denoising parameters. Each denoising parameter corresponds to a set of associated device information. Each set of associated device information includes first device information of one communication terminal and second device information of one audio player. The types of the communication terminals corresponding to different denoising parameters can be the same or different, for example, part of the communication terminals are interphones, and the other part of the communication terminals can be mobile phones and the like. The types of the audio players corresponding to different denoising parameters can be the same or different, for example, part of the audio players are Bluetooth headphones, and the other part of the audio players are Bluetooth sound boxes. Several of the embodiments of the present disclosure refer to one and more.
Specifically, the main control unit in the communication terminal stores preset parameter configuration information. And the preset parameter configuration information comprises a plurality of denoising parameters. Each denoising parameter corresponds to a set of associated device information. Each set of associated device information includes first device information of one communication terminal and second device information of one audio player. The preset parameter configuration information comprises a plurality of groups, denoising parameters in each group of preset parameter configuration information can be different and identical, and associated equipment information corresponding to each denoising parameter in different groups of preset parameter configuration information can be identical or different. The first device information or the second device information of each group of associated device information in the same group of preset parameter configuration information may be the same, or the first device information and the second device information may be different. Illustratively, the first device information and the second device information included in each set of associated device information in the set of preset parameter configuration information are the same and different.
As described above, the target denoising parameters include target echo cancellation parameters and target denoising parameters. The preset parameter configuration information may include preset echo cancellation parameter configuration information and preset noise reduction parameter configuration information. The echo cancellation parameter configuration information and the preset noise reduction parameter configuration information may be represented by a parameter configuration list, and the group of parameter configuration information may be in the form of "first device information-second device information-echo cancellation parameter-noise reduction parameter" for example.
The mode of determining the denoising parameters corresponding to the first device information and the second device information from the preset parameter configuration information may be: and (3) matching the first equipment information and the second equipment information acquired in the step (S11) with the first equipment information and the second equipment information in each group of parameter configuration information in the preset parameter configuration information, and taking the echo cancellation parameters corresponding to the group as target echo cancellation parameters and the noise reduction parameters of the group as target noise reduction parameters under the condition that the first equipment information and the second equipment information are successfully matched with the first equipment information and the second equipment information in the same group.
As described above, the target denoising parameters include target echo cancellation parameters and target denoising parameters. In some disclosed embodiments, the target denoising parameter determined according to the above manner may be a denoising parameter of a communication terminal, or may be a denoising parameter of an audio player, or may be a denoising parameter of a part of the target denoising parameters of the communication terminal, or a denoising parameter of another part of the target denoising parameters of the audio player. Wherein the echo cancellation process and the noise reduction process are independent of each other, and the two processes may be performed by different devices.
In an exemplary embodiment, in a case where the audio player has turned on the echo cancellation function and the noise reduction function, the determined target echo cancellation parameter is an echo cancellation parameter of the audio player, and the target noise reduction parameter is a noise reduction parameter of the audio player. In an exemplary embodiment, the determined target echo cancellation parameter and target noise reduction parameter are the echo cancellation parameter and noise reduction parameter of the communication terminal when the audio player does not turn on the echo cancellation function and the noise reduction function. In an exemplary embodiment, in a case where the audio player has turned on the echo cancellation function and has not turned on the noise reduction function, the determined target echo cancellation parameter is an echo cancellation parameter of the audio player, and the target noise reduction parameter is a noise reduction parameter of the communication terminal. In an exemplary embodiment, when the audio player has turned on the noise reduction function and has not turned on the echo cancellation function, the determined target echo cancellation parameter is an echo cancellation parameter of the communication terminal, and the determined target noise reduction parameter is a noise reduction parameter of the audio player.
The step S13 may include the steps of:
and responding to the target denoising parameters as the denoising parameters of the communication terminal, denoising the audio data to be processed based on the target denoising parameters to obtain target audio data, and sending the target audio data to an audio player for playing.
In some application scenarios, in response to the target denoising parameter being an echo cancellation parameter and a denoising parameter of the communication terminal, the communication terminal performs echo cancellation processing and denoising processing on audio data to be processed based on the target echo cancellation parameter and the target denoising parameter, so as to obtain target audio data.
And responding to the target denoising parameters as the denoising parameters of the audio player, and sending the audio data to be processed and the target denoising parameters to the audio player so that the audio player performs denoising processing on the audio data to be processed based on the target denoising parameters and plays the denoised target audio data.
In some application scenarios, in response to the target denoising parameters being the echo cancellation parameters and the noise reduction parameters of the audio player, the audio data to be processed, the target echo cancellation parameters and the target noise reduction parameters are sent to the audio player, so that the audio player performs noise reduction processing and echo cancellation processing on the audio data to be processed based on the target noise reduction parameters and the target echo cancellation parameters, and plays the target audio data subjected to the noise reduction processing and the echo cancellation processing.
And responding to the target denoising parameters as a first denoising parameter of the communication terminal and a second denoising parameter of the audio player, and after denoising processing corresponding to the first denoising parameter is performed on the audio data to be processed based on the first denoising parameter, sending the processed audio data to the audio player so that the audio player performs denoising processing corresponding to the second denoising parameter on the processed audio data based on the second denoising parameter.
In some application scenarios, when the first denoising parameter is a target echo cancellation parameter, the second denoising parameter is a target denoising parameter, the denoising process corresponding to the first denoising parameter is an echo cancellation process, and the denoising process corresponding to the second denoising parameter is a denoising process. When the first denoising parameter is a target denoising parameter, the second denoising parameter is a target echo cancellation parameter, denoising processing corresponding to the first denoising parameter is denoising processing, and denoising processing corresponding to the second denoising parameter is echo cancellation processing.

Step S33: the communication terminal and/or the audio player are configured based on the target echo cancellation parameters and the target noise reduction parameters.
Illustratively, if the target echo cancellation parameter and the target noise reduction parameter are both denoising parameters of the communication terminal, the denoising parameters of the communication terminal are configured by using the target echo cancellation parameter and the target noise reduction parameter. For example, if the target echo cancellation parameter and the target noise reduction parameter are both denoising parameters of the audio player, the communication terminal sends the target echo cancellation parameter and the target noise reduction parameter to the audio player so that the audio player configures the denoising parameters. For example, if the target echo cancellation parameter is an echo cancellation parameter of the communication terminal and the target noise reduction parameter is a noise reduction parameter of the audio player, the echo cancellation parameter of the communication terminal is configured by using the target echo cancellation parameter, and the communication terminal sends the target noise reduction parameter to the audio player so that the audio player configures the noise reduction parameter. For example, if the target noise reduction parameter is an echo cancellation parameter of the communication terminal, the target echo cancellation parameter is a noise reduction parameter of the audio player, the noise reduction parameter of the communication terminal is configured by using the target noise reduction parameter, and the communication terminal sends the target echo cancellation parameter to the audio player, so that the audio player configures the echo cancellation parameter.
Step S34: the configuration is completed and the communication terminal and the audio player start to operate.
The communication terminal carries out denoising processing on the audio data to be processed according to the configured denoising parameters, and sends the audio data subjected to denoising processing to the audio player, so that the audio player plays final audio data after carrying out corresponding denoising processing on the audio data according to the configured denoising parameters. Of course, if the communication terminal or the audio player does not perform the related configuration, the communication terminal or the audio player does not perform the corresponding denoising process, and if the audio player does not use the target echo cancellation parameter to perform the configuration, the audio player does not perform the echo cancellation process on the audio data, and the other cases are similar, which is not repeated here.
According to the scheme, the target denoising parameters are determined according to the equipment information of the communication terminal and the audio player, and then the denoising processing of the audio data to be processed is realized by using the target denoising parameters.

By way of example, a flexible collocation of communication terminals of different models and different audio players can be achieved, and better configuration of echo cancellation and noise reduction parameters.
In addition, the echo cancellation function and the noise reduction function of the communication terminal and the audio player are also intelligently switched, for example, in the case that the audio player starts the echo cancellation function, in order to prevent the situation that the sound quality is poor due to two times of echo cancellation on the same audio data, the echo cancellation function of the communication terminal can be closed.
