[0033] A control method for a vehicle audio system provided in an embodiment of the present application obtains first sound effect parameters corresponding to a first sound source by inputting second information determined based on first information into a trained sound effect analysis model, wherein the first information at least includes audio features, singing features, music style features and instrumentation features of the first sound source, and determines second sound effect parameters corresponding to the first sound source based on sound source sound field information of the vehicle and audio information of the vehicle's audio system, and determines target sound effect parameters corresponding to the first sound source based on the first sound effect parameters and the second sound effect parameters, and adjusts the sound effect parameters of the audio system to the target sound effect parameters when the first sound source is played, comprehensively considering the effects of the characteristics of the sound source itself, the sound source sound field information of the vehicle and the audio information of the vehicle's audio system on the sound quality, thereby improving the sound quality of the vehicle audio system and the auditory experience of the driver and passengers.

[0034] Optionally, the audio features of the first sound source include file features, statistical features, frequency domain features, and time domain features of the first sound source. The file features may include file formats such as MP3, WAV, and Dolby formats, the statistical features may include file accuracy, sampling rate, and bit depth information, the frequency domain features refer to frequency characteristics obtained by calculating Fourier transform, and may include frequency components and frequency structures, and the time domain features may include duration.

[0035] Optionally, the singing characteristics of the first sound source include the singing language, gender of the singer, number of singers and singing space of the first sound source, wherein the singing space can characterize whether the first sound source is a live singing version or an original version.

[0036] In one embodiment, before inputting the second information into the trained sound effect analysis model in step S101 to obtain the first sound effect parameter corresponding to the first sound source, the control method provided in the embodiment of the present application also includes: obtaining the first sound source; performing feature extraction on the first sound source to determine feature information of the first sound source.

[0037] Optionally, the first sound source is a digital sound source, which may be an audio signal provided by a device such as a car music APP, a car CD, a USB device, a mobile phone connected to the vehicle via Bluetooth, or the like.

[0038] In one embodiment, a preset feature extraction rule can be used to extract features from the first sound source to obtain feature information of the first sound source, or the first sound source can be input into a trained first feature processing model and feature extraction can be performed on the first sound source through the first feature processing model to obtain feature information of the first sound source.

[0039] In one implementation, before extracting features from the first sound source and determining feature information of the first sound source, the control method provided in the embodiment of the present application further includes: preprocessing the first sound source.

[0040] Optionally, the preprocessing includes at least one of removing a DC component, correcting a sampling error, and filtering.

[0041] The embodiment of the present application can ensure the purity of the first sound source by obtaining the first sound source and preprocessing the first sound source, and further improve the accuracy of determining the characteristic information of the first sound source by performing feature extraction on the preprocessed first sound source, so that the vehicle audio system can maximize the restoration of the characteristics of the sound source itself based on the target sound effect parameters determined according to the characteristic information of the first sound source, thereby improving the sound quality of the vehicle audio system and the user's auditory experience.

[0042] Optionally, the first information also includes user listening preference information, and / or the audio type and layout of the vehicle audio system, wherein the audio type and layout include the type, installation location, installation direction and number of each type of audio in the vehicle audio system.

[0043] Among them, the user's listening preference information can represent the user's listening habits, and can be extracted based on the user's operation information during the listening process. The operation information may include sound effect parameter selection information. In actual implementation, the user's listening preference information can be extracted based on the user's operation information related to the selection of sound effect parameters. The operation information can also include music selection information. For example, during the user's listening process, if the number of times the user switches rock songs to other songs exceeds the preset number, the user's preference information that he does not like to listen to rock music can be obtained. For example, in the user's playback history, the proportion of the playback time of singer A's songs is higher than the preset proportion, the user's preference information that he likes to listen to singer A's songs can be obtained.

The equalizer setting of the vehicle audio system may be adjusted based on the installation direction and installation position of the various audios in the vehicle audio system to improve the sound quality of the vehicle audio system.

[0045] In one embodiment, before inputting the second information into the trained sound effect analysis model in the above step S101 to obtain the first sound effect parameter corresponding to the first sound source, the control method provided in the embodiment of the present application further includes:

[0046] determining the first information as the second information;

[0047] The second information includes at least characteristic information of the first sound source, and may also include user music preference information, and / or the audio type and layout of the vehicle audio system.

[0048] In another embodiment, before inputting the second information into the trained sound effect analysis model in the above step S101 to obtain the first sound effect parameter corresponding to the first sound source, the control method provided in the embodiment of the present application further includes any of the following:

[0049] Based on preset feature fusion and conversion rules, feature fusion and conversion are performed on the first information to obtain second information;

[0050] The first information is input into the trained second feature processing model, and the second feature processing model is used to perform feature fusion and conversion on the first information to obtain the second information.

[0051] The first feature processing model and the second feature processing model can be the same feature processing model or different feature processing models. Optionally, the first feature processing model and the second feature processing model are the same feature processing model established based on the TensorFlow open source machine learning framework, and the model can include at least one of a recurrent neural network (RNN), a convolutional neural network (CNN), and a deep neural network (DNN). In actual implementation, the dynamic characteristics of the RNN network can be used to record and process the time series characteristics of the first sound source, so as to capture the cyclic characteristics of the first sound source and generate the pre-judgment parameters. The convolution operation of the CNN network can also be used to extract local features from the first sound source and precipitate effective information to provide support for further feature analysis and model training. The DNN network can also be used to learn the deep structure of the first sound source to identify and understand more complex and abstract features in the first sound source. Further, the feature processing model can continuously optimize its own model parameters by learning the inherent laws of the features, and improve the accuracy of feature extraction, feature fusion and conversion.

[0052] Optionally, when the second information is a vector, the second information includes at least an audio feature vector generated based on the audio features, singing features, music style features and orchestration features of the first sound source, and may also include a user preference vector generated based on the user's song preference information, and may also include an audio parameter vector generated based on the type of each audio and the number of each type of audio, as well as a vehicle space vector generated based on the installation position and installation direction of each audio.

[0053] In one embodiment, before inputting the second information into the trained sound effect analysis model in the above step S101 to obtain the first sound effect parameter corresponding to the first sound source, the control method provided in the embodiment of the present application further includes:

[0054] When the second information is a vector, generating a user preference vector according to the user's song preference information; and / or

[0055] When the second information is a vector, an audio parameter vector is generated according to the type of each audio and the number of each type of audio, and a vehicle space vector is generated according to the installation position and installation direction of each audio;

[0056] Among them, the second information includes an audio feature vector generated based on the audio features, singing features, music style features and orchestration features of the first sound source, and also includes a user preference vector, and / or an audio parameter vector and a vehicle space vector.

[0057] Based on the characteristic information of the sound source, the embodiment of the present application can further combine the user preference information, as well as the sound type and layout of the vehicle sound system, to determine the target sound effect parameters, so that the vehicle sound system can not only maximize the restoration of the characteristics of the sound source itself based on the target sound effect parameters, but also meet the user's personalized needs for sound effects, and can also enable the vehicle sound system to enhance the detail performance, dynamic range and sense of direction of the sound source based on the target sound effect parameters, thereby improving the clarity and fullness of the sound quality, and providing a more immersive and realistic listening experience for the driver and passengers.

[0058] like Figure 2As shown, in an application scenario, the first sound source can be input into a trained feature processing model, and the feature processing model is first used to extract features of the first sound source to determine the audio features, singing features, music style features and instrumentation features of the first sound source, and then the audio features, singing features, music style features and instrumentation features of the first sound source are fused and converted through the feature processing model to obtain the audio feature vector of the first sound source. In addition, the user's song preference information can be input into the trained feature processing model to obtain the user preference vector, the type of each audio and the number of each type of audio can be input into the trained feature processing model to obtain the audio parameter vector, and the installation position and installation direction of each audio can be input into the trained feature processing model to obtain the vehicle space vector. Furthermore, the audio feature vector, user preference vector, audio parameter vector and vehicle space vector can be input into the trained sound effect analysis model to obtain the first sound effect parameter corresponding to the first sound source.

[0059] Optionally, the above-mentioned sound effect analysis model includes a hidden layer, an output layer and an optimizer. Among them, after the audio feature vector, user preference vector, sound parameter vector and vehicle space vector are input into the trained sound effect analysis model, the sound effect analysis model can use the activation function to add nonlinearity (such as ReLU) to the vector of the input sound effect analysis model through the hidden layer, and then use the activation function classification task (such as softmax) to the output result of the hidden layer through the output layer, and then the output result of the output layer can be gradient optimized (such as Adam) through the optimizer, and finally the first sound effect parameter corresponding to the first sound source is output. Before the audio feature vector, user preference vector, sound parameter vector and vehicle space vector are input into the trained sound effect analysis model, the sound effect analysis model can be iteratively trained using classification and gradient algorithms to obtain a trained sound effect analysis model.

[0060] It is worth mentioning that the vector is only an example of a format of the second information that is easy to recognize by the sound effect analysis model, and this application does not limit the format of the second information.

[0061] The embodiment of the present application extracts features, fuses features and converts the first sound source through a trained feature processing model to obtain an audio feature vector of the first sound source, which can improve the efficiency and accuracy of feature extraction, feature fusion and conversion, and can improve the efficiency and accuracy of the sound effect analysis model performing sound effect analysis based on the second information. Further, by generating a user preference vector based on the user's song preference information through a trained feature processing model, and / or by converting the feature processing model based on the type of each sound and the number of each type of sound to generate a sound parameter vector, and generating a vehicle space vector based on the installation position and installation direction of each sound, the efficiency and accuracy of the sound effect analysis model performing sound effect analysis based on the second information can be further improved.

[0062] In one embodiment, before inputting the second information into the trained sound effect analysis model in the above step S101 to obtain the first sound effect parameter corresponding to the first sound source, the control method provided in the embodiment of the present application further includes:

[0063] Obtaining a training data set, wherein the training data set includes a plurality of training samples, each training sample includes a third information and a playback sound effect parameter corresponding to the second sound source; the third information is determined based on the fourth information; the fourth information includes at least an audio feature, a singing feature, a music style feature, and an instrumentation feature of the second sound source;

[0064] For each training sample, perform the following steps:

[0065] Input the training samples into the sound effect analysis model to obtain the predicted sound effect parameters of the vehicle audio system;

[0066] Determine the loss function value of the sound effect analysis model according to the predicted sound effect parameters and the played sound effect parameters;

[0067] When the loss function value does not meet the training stop condition, the model parameters of the sound effect analysis model are adjusted to obtain an updated sound effect analysis model, and the updated sound effect analysis model is trained with the next training sample until the training stop condition is met to obtain a trained sound effect analysis model.

[0068] Among them, the playback sound effect parameters corresponding to the second sound source are the optimal sound effect parameters for playing the second sound source, which are at least related to the characteristic information of the second sound source, and can also be related to the user preference information, and / or the sound type and layout of the vehicle sound system. The sound effect parameters can be obtained through experiments. Specifically, the playback sound effect parameters can be selected based on the correlation between the predicted sound effect parameters and the above information. Exemplarily, when the training sample is determined based on the characteristic information of the second sound source and the user preference information, the predicted sound effect parameters are related to the characteristic information of the second sound source and the user preference information, and the playback sound effect parameters can be selected based on the characteristic information of the second sound source and the user preference information. The second sound source and the above-mentioned first sound source can be the same sound source or different sound sources.

[0069] The embodiment of the present application determines the loss function value of the sound effect analysis model by determining the predicted sound effect parameters and the played sound effect parameters obtained based on the training samples, thereby ensuring the training effect of the sound effect analysis model. By using the trained sound effect analysis model, the efficiency and accuracy of determining the first sound effect parameters corresponding to the first sound source based on the second information can be improved, thereby enabling the vehicle audio system to maximize the restoration of the characteristics of the sound source itself based on the first sound effect parameters or the target sound effect parameters determined based on the first sound effect parameters, and improve the sound quality of the vehicle audio system and the user's auditory experience.

[0070] In one embodiment, before determining the second sound effect parameter corresponding to the first sound source according to the sound source sound field information of the vehicle and the sound information of the sound system of the vehicle in the above step S102, the control method provided by the embodiment of the present application further includes:

[0071] Determine the sound field position of the sound source according to the distribution position of the drivers and passengers;

[0072] Determine the sound source sound field height according to the ear height of the driver and passengers;

[0073] The audio power distribution parameters are determined based on the link relationship between the audio system's power amplifier channels and the audio systems in the audio system, the number of power amplifier channels, the audio source sound field position, and the audio source sound field height.

[0074] Optionally, the distribution position of the driver and passengers includes the number of the driver and passengers and the position of each driver and passenger. In actual implementation, the camera can be used to collect images in the car, and the distribution position and ear height of the driver and passengers can be obtained by image recognition technology. Further, the sound source sound field position can be obtained by calling a pre-stored sound source sound field position calculation formula and substituting the distribution position of the driver and passengers into the sound source sound field position calculation formula, and the sound source sound field height can be obtained by calling a sound source sound field height calculation formula and substituting the ear height of the driver and passengers into the sound source sound field height calculation formula; the sound power distribution parameter can also be obtained by calling a pre-stored sound power distribution parameter calculation formula and substituting the link relationship between the power amplifier channel of the sound system and each sound in the sound system, the number of power amplifier channels, the sound source sound field position and the sound source sound field height into the sound power distribution parameter calculation formula. In addition, in actual implementation, the distribution positions of the driver and passengers, the height of their ears, the link relationship between the power amplifier channels of the audio system and the audio systems in the audio system, the number of power amplifier channels, the sound source sound field position and the sound source sound field height can also be input into the trained first information processing model to obtain the sound source sound field position, the sound source sound field height and the audio power distribution parameters.

[0075] The embodiments of the present application can accurately determine the location of the sound field of the sound source based on the distribution position of the driver and passengers, can accurately determine the height of the sound field of the sound source based on the ear height of the driver and passengers, and can accurately determine the audio power allocation parameters based on the link relationship between the power amplifier channel of the audio system and each audio in the audio system, the number of power amplifier channels, the location of the sound field of the sound source, and the height of the sound field of the sound source. This ensures that when the first audio source is played with the target sound effect parameters determined by integrating the sound source sound field information of the vehicle and the audio information of the vehicle audio system, the sound field of the first audio source can match the location and ear height of the driver and passenger, thereby providing a customized audio experience for each driver and passenger, and improving the sound quality of the vehicle audio system and the auditory experience of the driver and passenger.

[0076] The second sound effect parameter in the above step S102 can be determined based on the sound source sound field information of the vehicle and the sound information of the vehicle sound system, combined with a preset sound effect determination rule, to determine the second sound effect parameter corresponding to the first sound source. The second sound effect parameter corresponding to the first sound source can also be obtained by inputting the sound source sound field information of the vehicle and the sound information of the vehicle sound system into a trained sound effect determination model.

[0077] By integrating the sound field information of the vehicle's sound source and the sound information of the vehicle's sound system, the embodiment of the present application can optimize the sound field information of the vehicle's sound source based on the type and layout of the vehicle's sound system, the number of power amplifier channels, and the link relationship between the power amplifier channels and each sound in the vehicle's sound system, and obtain the second sound effect parameters, thereby ensuring that when the first sound source is played with the target sound effect parameters determined based on the second sound effect parameters, the sound field of the first sound source can match the position and ear height of the driver and passenger, thereby providing a customized sound experience for each driver and passenger, and improving the sound quality of the vehicle's sound system and the auditory experience of the driver and passenger.

[0078] In one embodiment, before inputting the sound source sound field information of the vehicle and the sound information of the vehicle's sound system into the trained sound effect determination model, the control method provided in the embodiment of the present application also includes: respectively inputting the sound source sound field position, the sound source sound field height, and the sound type and layout into the trained second information processing model to obtain the sound source sound field position vector, the sound source sound field height vector, and the sound parameter vector.

[0079] The second sound effect parameters in step S102 can also be obtained by inputting the sound source sound field position vector, the sound source sound field height vector, the sound parameter vector and the sound power allocation parameter into the trained sound effect determination model to obtain the second sound effect parameters corresponding to the first sound source. The first information processing model and the second information processing model can be the same information processing model or different information processing models.

[0080] like Figure 3As shown, in an application scenario, the distribution position of the driver and the occupants, the ear height of the driver and the occupants, the audio type and layout of the vehicle audio system, the link relationship between the power amplifier channel and each audio in the vehicle audio system, and the number of power amplifier channels can be respectively input into the trained information processing model. First, the sound source sound field position can be determined based on the distribution position of the driver and the occupants through the information processing model, and the sound source sound field height can be determined based on the ear height of the driver and the occupants through the information processing model, and the sound power allocation parameter can be determined based on the link relationship between the power amplifier channel and each audio in the vehicle audio system, the number of power amplifier channels, the sound source sound field position and the sound source sound field height through the information processing model. Then, the sound source sound field position, the sound source sound field height, and the audio type and layout can be converted into vector format through the information processing model to obtain the sound source sound field position vector, the sound source sound field height vector, and the audio parameter vector. Finally, the sound source sound field position vector, the sound source sound field height vector, the audio parameter vector, and the audio power allocation parameter are respectively input into the trained sound effect determination model to obtain the second sound effect parameter corresponding to the first sound source.

[0081] The training process of the above-mentioned information processing model can refer to the training process of the above-mentioned feature processing model, and the training process of the above-mentioned sound effect determination model can refer to the training process of the above-mentioned sound effect analysis model, which will not be repeated here.

[0082] It is worth mentioning that the vector is only an example of a format for facilitating the identification of the sound effect determination model. This application does not restrict the format of the sound source sound field position, sound source sound field height, sound type and layout.

[0083] The embodiment of the present application, based on the accurate determination of the audio type and layout, audio power allocation parameters, sound source sound field position and sound source sound field height, obtains the sound source sound field position vector, the sound source sound field height vector and the audio parameter vector by inputting the sound source sound field position, the sound source sound field height, the audio type and layout into a trained second information processing model, thereby improving the efficiency and accuracy of the sound effect determination model in determining the second sound effect parameters based on the audio power allocation parameters, the audio type and layout, the sound source sound field position and the sound source sound field height.

[0084] Optionally, the first sound effect parameter includes at least one type of sound effect parameter and a first value of each type of sound effect parameter. Optionally, the second sound effect parameter includes at least one type of sound effect parameter and a second value of each type of sound effect parameter. Optionally, the target sound effect parameter includes each type of sound effect parameter in the first sound effect parameter and a target value of each type of sound effect parameter.

[0085] In one embodiment, the step S103 of determining the target sound effect parameter corresponding to the first sound source according to the first sound effect parameter and the second sound effect parameter includes:

[0086] For each type of sound effect parameter in the first set of first sound effect parameters, determining the second value of the sound effect parameter as a target value;

[0087] For each type of sound effect parameter in the second set of first sound effect parameters, determining a first value of the sound effect parameter as a target value;

[0088] The first set is a set of sound effect parameters common to the first sound effect parameter and the second sound effect parameter; the second set is a set of sound effect parameters in the first sound effect parameter that are not common to the first sound effect parameter and the second sound effect parameter.

[0089] The embodiment of the present application determines the second value of the sound effect parameter as the target value for each type of sound effect parameter in the first set of the first sound effect parameter, and determines the first value of the sound effect parameter as the target value for each type of sound effect parameter in the second set of the first sound effect parameter. The sound effect parameters in the first sound effect parameter that are highly correlated with the sound field position and / or the sound field of the sound source can be corrected to obtain the target sound effect parameters, so that the vehicle audio system can not only maximize the restoration of the characteristics of the sound source itself based on the target sound effect parameters, but also provide a customized audio experience for each driver and passenger, thereby improving the sound quality of the vehicle audio system and the auditory experience of the driver and passenger.

[0090] Optionally, the first sound effect parameter includes at least one type of sound effect parameter and a first value of each type of sound effect parameter. Optionally, the second sound effect parameter includes a positioning accuracy and a second value of the positioning accuracy. Optionally, the target sound effect parameter includes each type of sound effect parameter in the first sound effect parameter and a target value of each type of sound effect parameter.

[0091] In another embodiment, the above step S103: determining the target sound effect parameter corresponding to the first sound source according to the first sound effect parameter and the second sound effect parameter, includes:

[0092] For each type of sound effect parameter in the first sound effect parameter, a target value of the sound effect parameter is determined according to a relationship between the sound effect parameter and the positioning accuracy, and a first value of the sound effect parameter and / or a second value of the positioning accuracy.

[0093] The embodiment of the present application determines the target value of the sound effect parameter for each type of sound effect parameter in the first sound effect parameter according to the relationship between the sound effect parameter and the positioning accuracy, as well as the first value of the sound effect parameter and / or the second value of the positioning accuracy, so that the vehicle audio system can not only maximize the restoration of the characteristics of the sound source itself based on the target sound effect parameter, but also provide a customized audio experience for each driver and passenger, thereby improving the sound quality of the vehicle audio system and the auditory experience of the driver and passenger.

[0094] In one embodiment, the target value of the sound effect parameter is determined based on the relationship between the sound effect parameter and the positioning accuracy, and the first value of the sound effect parameter and / or the second value of the positioning accuracy, including:

[0095] In the case where the sound effect parameter is the positioning accuracy, determining the second value of the positioning accuracy as the target value of the sound effect parameter;

[0096] In a case where the sound effect parameter is related to the positioning accuracy, determining a target value of the sound effect parameter according to a first value of the sound effect parameter and a second value of the positioning accuracy;

[0097] In a case where the sound effect parameter is irrelevant to the positioning accuracy, the first value of the sound effect parameter is determined as the target value of the sound effect parameter.

[0098] Optionally, the first sound effect parameter includes at least one type of sound effect parameter selected from the group consisting of frequency range filter, positioning accuracy, frequency response, sensitivity, stereo separation, crossover frequency, equalizer setting, and sound field width. When the sound effect parameter is any one of sound field width, sensitivity, crossover frequency, and frequency response, the sound effect parameter is related to positioning accuracy; when the sound effect parameter is any one of frequency range filter, stereo separation, and equalizer setting, the sound effect parameter is related to positioning accuracy.

[0099] In the embodiment of the present application, when the sound effect parameter is the positioning accuracy, the second value of the positioning accuracy is determined as the target value of the sound effect parameter; when the sound effect parameter is related to the positioning accuracy, the target value of the sound effect parameter is determined according to the first value of the sound effect parameter and the second value of the positioning accuracy; when the sound effect parameter is unrelated to the positioning accuracy, the first value of the sound effect parameter is determined as the target value of the sound effect parameter, so that the vehicle audio system can not only maximize the restoration of the characteristics of the sound source itself based on the target sound effect parameter, but also provide a customized audio experience for each driver and passenger, thereby improving the sound quality of the vehicle audio system and the auditory experience of the driver and passenger.

[0100] In the case where the sound effect parameter is related to the positioning accuracy, the target value of the sound effect parameter is determined according to the first value of the sound effect parameter and the second value of the positioning accuracy. The target value of the sound effect parameter can be obtained by substituting the first value of the sound effect parameter and the second value of the positioning accuracy into a preset relationship, wherein the preset relationship can be determined based on the correlation between the sound effect parameter and the positioning accuracy. The first value of the sound effect parameter and the second value of the positioning accuracy can also be fused according to a preset fusion rule to obtain the target value of the sound effect parameter.

[0101] In the embodiment of the present application, when the sound effect parameters are related to the positioning accuracy, the target value of the sound effect parameter is determined by fusing the value of the sound effect parameter in the first sound effect parameter with the positioning accuracy value in the second sound effect parameter. This allows the vehicle audio system to not only maximize the restoration of the characteristics of the sound source itself based on the target sound effect parameter, but also provide a customized audio experience for each driver and passenger, thereby improving the sound quality of the vehicle audio system and the auditory experience of the driver and passenger.

[0102] Combination Figure 3 and Figure 4 In one application scenario, the first sound source can be input into a trained feature processing model. First, the feature processing model is used to extract features of the first sound source to determine the audio features, singing features, music style features and instrumentation features of the first sound source. Then, the feature processing model is used to fuse and transform the audio features, singing features, music style features and instrumentation features of the first sound source to obtain an audio feature vector of the first sound source. In addition, the user's song preference information can be input into a trained feature processing model to obtain a user preference vector. The type of each audio and the number of each type of audio can be input into a trained feature processing model to obtain an audio parameter vector. The installation position and installation direction of each audio can also be input into a trained feature processing model to obtain a vehicle space vector. Furthermore, the audio feature vector, user preference vector, audio parameter vector and vehicle space vector can be input into a trained sound effect analysis model to obtain the first sound effect parameter corresponding to the first sound source.

[0103] In addition, the distribution position of the driver and the occupants, the ear height of the driver and the occupants, the audio type and layout of the vehicle audio system, the link relationship between the power amplifier channel and each audio in the vehicle audio system, and the number of the power amplifier channels can be respectively input into the trained information processing model. First, the sound source sound field position can be determined based on the distribution position of the driver and the occupants through the information processing model, and the sound source sound field height can be determined based on the ear height of the driver and the occupants through the information processing model, and the sound power allocation parameter can be determined based on the link relationship between the power amplifier channel and each audio in the vehicle audio system, the number of power amplifier channels, the sound source sound field position and the sound source sound field height through the information processing model. Then, the sound source sound field position, the sound source sound field height, and the audio type and layout can be converted into vector format respectively through the information processing model to obtain the sound source sound field position vector, the sound source sound field height vector, and the sound parameter vector. Then, the sound source sound field position vector, the sound source sound field height vector, the sound parameter vector, and the sound power allocation parameter can be respectively input into the trained sound effect determination model to obtain the second sound effect parameter corresponding to the first sound source.

[0104] Furthermore, for each type of sound effect parameter in the first sound effect parameter, a target value of the sound effect parameter can be determined according to the relationship between the sound effect parameter and the positioning accuracy, and the first value of the sound effect parameter in the first sound effect parameter and / or the second value of the positioning accuracy in the second sound effect parameter. Finally, when playing the first sound source, the sound effect parameter of the vehicle audio system can be adjusted to the target sound effect parameter, so that the vehicle audio system plays the first sound source based on the target sound effect parameter.

[0105] The embodiment of the present application obtains the first sound effect parameters corresponding to the first sound source by inputting the second information determined based on the characteristic information of the first sound source into the trained sound effect analysis model, and determines the second sound effect parameters corresponding to the first sound source according to the sound source sound field information of the vehicle and the sound information of the vehicle's sound system, and determines the target value of the sound effect parameter for each type of sound effect parameter in the first sound effect parameter according to the relationship between the sound effect parameter and the positioning accuracy, and the first value of the sound effect parameter in the first sound effect parameter and / or the second value of the positioning accuracy in the second sound effect parameter, so that when the first sound source is played, the vehicle sound system can not only maximize the restoration of the characteristics of the sound source itself based on the target sound effect parameters, but also provide a customized sound experience for each driver and passenger, thereby improving the sound quality of the vehicle sound system and the auditory experience of the driver and passenger.
