The embodiment shown in fig. 2 is extended based on the embodiment shown in fig. 1, and the differences between the embodiment shown in fig. 2 and the embodiment shown in fig. 1 will be emphasized below, and the descriptions of the same parts will not be repeated.

As shown in fig. 2, in the audio processing method provided in the embodiment of the present application, before the step of controlling the wireless headset based on the control instruction, the following steps are further included.

In step S20, an audio file to be played is determined based on the control instruction and the audio file stored in the audio module.

Illustratively, a user sends a control instruction for an audio file within a range of the audio file stored in the audio module by operating a mobile phone or a tablet computer, where the control instruction includes a selection instruction and a confirmation instruction for the audio file, and then the wireless headset determines the audio file to be played selected by the user based on the control instruction.

And, in this application embodiment, the step of controlling the wireless headset based on the control instruction includes the following steps.

And step S31, controlling the earphone local equalizer to determine the equalization parameter corresponding to the audio file to be played based on the control instruction, so that the earphone local equalizer performs the spectrum equalization operation on the audio file to be played based on the equalization parameter, and controlling the wireless earphone to play the audio file to be played after the spectrum equalization operation.

Illustratively, the audio module includes a headphone local equalizer. The local equalizer of the earphone can be obtained by setting an FIR filter or an IIR filter. The earphone local equalizer determines the related information of the music type, the music style, the musicians, the albums, the single music and even the words and sentences in the single music of the audio file to be played based on the control instruction, determines the equalization parameters of the audio file to be played based on the related information, and then performs the spectrum equalization operation on the audio file to be played, so that the wireless earphone can play the audio file to be played after the spectrum equalization operation.

Fig. 3 is a schematic flowchart illustrating a process of determining an equalization parameter corresponding to an audio file to be played according to an exemplary embodiment of the present application. The embodiment shown in fig. 3 is extended based on the embodiment shown in fig. 2, and the differences between the embodiment shown in fig. 3 and the embodiment shown in fig. 2 will be emphasized below, and the descriptions of the same parts will not be repeated.

As shown in fig. 3, in the audio processing method provided in the embodiment of the present application, the step of determining the equalization parameter corresponding to the audio file to be played includes the following steps.

Step S311, determining target frequency response information of the earphone corresponding to the audio file to be played.

Illustratively, the earphone target frequency response information is the frequency response of the system (including circuitry and space) through which the target sound source (e.g., binary data stored in the audio module) is converted from an electrical signal to an acoustic signal received by the eardrum of the human ear. For example, the headphone target frequency response information is determined based on a Harman curve or a Pittsmet curve.

The target frequency response information of the earphone can be fixed and unchangeable, and the equalization parameters can be updated through new earphone firmware issued by the cloud so as to adapt to the current Harman curve or the Vomette curve. The target headphone frequency response information may also be variable, such as information related to the genre of music, style of music, musicians, albums, single music, or even words and phrases in the single music of the audio file to be played. That is, it can be understood that different audio files to be played have different headphone target frequency response information. For example, when the playing audio of the wireless headset is switched from the audio file a to the audio file B, the target frequency response information of the headset is also switched accordingly, and the target frequency response information of the headset corresponding to the audio file a is switched to the target frequency response information of the headset corresponding to the audio file B.

For example, when the target frequency response information of the headphones may vary, the user may determine the target frequency response information of the headphones corresponding to the audio file to be played in the following manner. The following modes are explained by taking an example of switching the audio file a to the audio file B.

a. And the wireless earphone locally responds to the switching instruction, obtains earphone target frequency response information corresponding to the audio file B, and then the wireless earphone locally determines and adjusts balance parameters according to the earphone target frequency response information corresponding to the audio file B.

b. And the wireless earphone locally determines and adjusts the balance parameters according to the earphone target frequency response information corresponding to the audio file B.

c. And the user switches the audio files through the wireless earphone application program, the electronic equipment terminal obtains the earphone target frequency response information corresponding to the audio file B, and determines the balance parameters according to the earphone target frequency response information corresponding to the audio file B, so that the balance parameters are sent to the wireless earphone locally to be adjusted.

In step S312, the speaker path transfer function information of the wireless headset is determined.

Illustratively, the speaker path transfer function information is determined based on a frequency response of an electro-acoustic conversion system between the speaker input to the eardrum of the human ear.

In step S313, an equalization parameter is determined based on the headphone target frequency response information and the speaker path transfer function information.

Illustratively, the target frequency response information of the earphone is tg (f), the transfer function information of the loudspeaker path is g (f), and the equalization parameter is EQ_e(f) In that respect Then, the ratio of the target frequency response information of the earphone to the transfer function information of the loudspeaking path is the equalization parameter, i.e. the following formula (1).

In the practical application process, the target frequency response information of the earphone corresponding to the audio file to be played is determined, the transfer function information of the loudspeaking path of the wireless earphone is determined, and then the balance parameter is determined based on the target frequency response information of the earphone and the transfer function information of the loudspeaking path.

The audio processing method provided by the embodiment of the application can achieve the purpose of determining the balance parameters corresponding to the audio file to be played. According to the method and the device, the tone quality of the audio file to be played can be adjusted to be optimal in a mode of performing spectrum balancing operation on the audio file to be played, and therefore the audio file to be played can be played in the state of the optimal tone quality.

Fig. 4 is a schematic flowchart illustrating a process of determining an equalization parameter corresponding to an audio file to be played according to another exemplary embodiment of the present application. The embodiment shown in fig. 4 is extended based on the embodiment shown in fig. 3, and the differences between the embodiment shown in fig. 4 and the embodiment shown in fig. 3 will be emphasized below, and the descriptions of the same parts will not be repeated.

As shown in fig. 4, in the audio processing method provided in the embodiment of the present application, the step of determining the target frequency response information of the earphone corresponding to the audio file to be played includes the following steps.

Step S3111, inputting the audio file to be played into the target frequency response model to determine the target frequency response information of the earphone.

Illustratively, the target frequency response model mentioned in step S3111 is a deep learning network model, and the target frequency response model is obtained by training through a model training method. Specifically, an initial network model is established, an audio file sample to be played and earphone target frequency response information corresponding to the audio file sample to be played are determined to generate training data, then the initial network model is trained based on the generated training data, model parameters of the initial network model are adjusted, and finally the target frequency response model is generated.

In some embodiments, the input data of the target frequency response model is an audio file to be played, and the output data is the target frequency response information of the earphone corresponding to the audio file to be played.

In the practical application process, firstly, an audio file to be played is input into a target frequency response model to determine target frequency response information of the earphone, then, the loud-speaking path transfer function information of the wireless earphone is determined, and then, the balance parameter is determined based on the target frequency response information of the earphone and the loud-speaking path transfer function information.

The audio processing method provided by the embodiment of the application can achieve the purpose of determining the balance parameters corresponding to the audio file to be played. Particularly, the method for determining the target frequency response information of the earphone corresponding to the audio file to be played is obtained by inputting the audio file to be played into the target frequency response model, and the characteristics of the target frequency response model can be customized based on the training data, so that the method can meet the personalized requirements of the determined target frequency response information of the earphone, and can improve the accuracy of the determined target frequency response information of the earphone to a certain extent.

To further satisfy the impulse requirements of the user, the embodiment shown in fig. 5 described below describes a scheme for user-defining equalization parameters.

Specifically, fig. 5 is a schematic flowchart illustrating a process of determining an equalization parameter corresponding to an audio file to be played according to another exemplary embodiment of the present application. The embodiment shown in fig. 5 is extended based on the embodiment shown in fig. 2, and the differences between the embodiment shown in fig. 5 and the embodiment shown in fig. 2 will be emphasized below, and the descriptions of the same parts will not be repeated.

As shown in fig. 5, in the audio processing method provided in the embodiment of the present application, the step of determining the equalization parameter corresponding to the audio file to be played includes the following steps.

Step S314, obtaining the user-defined equalization parameters of the user.

In one embodiment of the present application, the user-defined equalization parameters are generated by a user subjectively adjusting a virtual equalizer. Illustratively, the user adjusts the virtual equalizer in the wireless headset application according to the personalized requirements, i.e., the corresponding customized equalization parameters can be generated.

Step S315, determining the equalization parameter corresponding to the audio file to be played based on the self-defined equalization parameter.

In an embodiment of the present application, after obtaining the user-defined equalization parameter of the user, the electronic device sends the user-defined equalization parameter to the local wireless headset, and the wireless headset determines the user-defined adjusted equalization parameter based on the user-defined equalization parameter and the equalization parameter before user-defined adjustment (i.e., the equalization parameter corresponding to the audio file to be played mentioned in step S315).

Illustratively, the user's custom equalization parameters are EQ_a(f) The target frequency response information of the earphone is Tg (f), and the equalization parameter before user-defined adjustment is EQ_e(f) The user-defined adjusted equalization parameter is EQ'_e(f) The formula is shown below.

EQ_a(f)·EQ_e(f)·G(f)＝EQ’_e(f)·G(f)＝EQ_a(f)·Tg(f) (2)

As can be seen from equation (2), when the user does not adjust the virtual equalizer, the equalization parameter is set to

The target earphone frequency response information is Tg (f), and after the user adjusts the virtual equalizer, the adjusted equalization parameter is set to EQ'_e(f)＝EQ_a(f)·EQ_e(f) The adjusted headphone target frequency response information is set to Tg' (f) ═ EQ_a(f) Tg (f), wherein Tg' (f) can be regarded as the earphone target frequency response information Tg (f) after user-defined adjustment.

According to the audio processing method provided by the embodiment of the application, the purpose of determining the equalization parameters corresponding to the audio file to be played is achieved by acquiring the user-defined equalization parameters of the user and then determining the equalization parameters corresponding to the audio file to be played based on the user-defined equalization parameters. Particularly, the user can be supported to customize the equalization parameters, so that the embodiment of the application meets the improvisation requirement of the user, and the hearing experience of the user is further improved.

In step S11, an audio switching instruction is determined based on the motion manipulation information of the user for the wireless headset.

Illustratively, the motion manipulation information includes gesture manipulation information, i.e., a user can manipulate the wireless headset through a gesture to perform a switching operation of an audio file. For example, the user determines to switch to the previous audio file by making an upward gesture and to switch to the next audio file by making a downward gesture within a range perceivable by the wireless headset. Furthermore, the wireless earphone locally responds to the switching instruction, and obtains earphone target frequency response information corresponding to the audio file to be switched, and then the wireless earphone determines and adjusts the balance parameters according to the earphone target frequency response information.

Illustratively, the action manipulation information includes key manipulation information, i.e., the user may determine an audio switch instruction by pressing a key on the wireless headset, e.g., the user determines to switch to a previous audio file by pressing an "up" key in the wireless headset interface and determines to switch to a next audio file by pressing a "down" key in the wireless headset interface.

In step S12, an audio switching instruction is determined based on instruction information of the user for the electronic device.

Illustratively, the user may switch audio by controlling the wireless headset in a motion-or voice-operated manner with the electronic device. For example, a user may switch to a previous audio file by saying "up" to the electronic device and may switch to a next audio file by saying "down" to the electronic device. For another example, the user determines to switch to the previous audio file by pressing the up key in the interface of the electronic device, and determines to switch to the next audio file by pressing the down key in the interface of the electronic device.
