Problems solved by technology
[0003] However, in the above process, because the excitation parameters of the previous audio frame are often poorly correlated with the subsequent lost audio frames, it will be difficult to accurately predict the information contained in the lost audio frame, and the audio frame recovery effect is poor.

The invention relates to an audio data processing method and device, computer equipment and a storage medium, and relates to the field of audio data processing. According to the invention, the methodcomprises the steps: obtaining a plurality of audio frames before a frame loss moment from an audio file during the frame loss of the audio file, and determining a target amplitude value and a targetphase of the frame loss moment according to the information contained in the audio frames because the audio information of the plurality of audio frames is highly correlated with the lost audio frames; and constructing a target audio frame corresponding to the frame loss moment based on the target amplitude value and the target phase, i.e., based on data of two dimensions of amplitude and phase, so the audio frame recovery accuracy can be effectively improved.
Description
technical field [0001] The present disclosure relates to the field of audio data processing, in particular to an audio data processing method, device, computer equipment and storage medium. Background technique [0002] With the development of mobile communication and the Internet, the application of audio technology is becoming more and more extensive. During the transmission of audio data, due to poor network environment and other reasons, frame loss events may occur, seriously affecting the audio quality. At present, in the audio data processing process, when a frame loss event occurs, the lost audio frame is usually constructed based on the excitation parameters corresponding to the previous audio frame of the lost audio frame. When continuous frame loss occurs, that is, multiple consecutive audio frames are lost, multiple lost audio frames need to be recovered based on the excitation parameters corresponding to the previous audio frame. [0003] However, in the above ...
