According to the method, the preset parameter category is obtained in advance according to the influence degree of the sound field parameters of the audio information on the sound field effect, and the corresponding target sound field parameters are determined from the current sound field parameters obtained by screening among the plurality of current sound field parameters of the audio information, so that the computing power can be reduced, and the efficiency and accuracy of adjusting the audio quality in different sound field environments can be improved.
In a specific implementation scenario, after deep learning training based on a neural network model, a sound field parameter screening model is constructed, after the sound field parameter screening model is input based on a plurality of current sound field parameters, a preset number of parameter categories with larger influence on the sound field effect in the current sound field environment are determined, and then the sound field parameters are screened from the plurality of current sound field parameters, so that the computational power can be reduced, and the efficiency and accuracy of adjusting the audio quality in different sound field environments can be improved.
In another specific implementation scenario, according to the current sound field effect in the vehicle, preset parameter types corresponding to the sound effects are preset, at least one current sound field parameter consistent with the preset parameter types is obtained by screening from a plurality of current sound field parameters of the audio information based on the current sound field effect, so that the calculation force can be reduced, and the efficiency and accuracy of audio quality adjustment under different sound field environments can be improved.
In one implementation scenario, an audio quality adjustment result may be obtained based on a current sound field parameter, a historical sound field parameter during a previous round of adjustment, and a historical target sound field parameter corresponding to the historical sound field parameter, where the audio quality adjustment result may be used to characterize an influence degree of the previous round of historical target sound field parameter on the current sound field effect, for example, when audio information is output to a current sound field environment after being adjusted according to the historical target sound field parameter, the obtained current sound field parameter is collected to indicate that the audio quality in the current sound field environment is improved, so that the historical target sound field parameter still accords with a parameter adjustment range required by the current sound field environment, or the obtained current sound field parameter is collected to indicate that the audio quality in the current sound field environment is reduced, so that the current sound field environment is greatly changed, the historical target sound field parameter does not accord with a parameter adjustment range required by the current sound field environment, and the target sound field parameter corresponding to the current sound field parameter may be obtained based on the audio quality adjustment result.

For example, the current sound pressure level in the current sound field parameters is 40 db, the target sound pressure level is 45 db, the corresponding sound pressure level compensation is 5 db, and the rest sound field compensation parameters are sequentially obtained based on the difference between the current sound field parameters and the corresponding target sound field parameters. According to the method, the sound field compensation parameter is obtained based on the difference value between the current sound field parameter and the target sound field parameter, and the sound field parameter information of the next output audio can be adjusted based on the sound field compensation parameter, so that the playing quality of the audio in the vehicle can be improved.
