Embodiment Construction

[0035] The present application has proposed an audio processing method that allows the computer device to obtain the audio lack of the audio clip when the target audio data in the target audio defects is acquired. Predict compensation, since the computer device predicts the audio lack of the target audio data, the upper and lower audio fragment of the audio deletion fragment in the target audio data is combined, so that the computer device implements the process of predicting the audio lack fragment. In the forehead, the fully utilization of the effective information in this target audio data can also increase the robustness of the computer device to predict the compensation of the audio deletion. In one embodiment, the target audio data may be a voice data, music data, or an audio portion in video data, wherein the call voice data may be historical data acquired from an instant communication application, or Is data generated in real time during the voice call, and the voice call ...

Abstract

The embodiment of the present invention discloses an audio processing method, related equipment, a storage medium and a program product, wherein the method includes: acquiring the target audio data to be processed and the spectrum information of the target audio data, and the target audio data contains audio The missing segment, the spectral information includes the spectral features of the context audio segment of the audio missing segment; according to the spectral features of the context audio segment, perform feature compensation processing on the spectral information of the target audio data to obtain the target audio The compensated spectrum information corresponding to the data; audio prediction is performed by using the compensated spectrum information to obtain predicted audio data; the audio missing segment in the target audio data is compensated according to the predicted audio data, and the compensation of the target audio data is obtained Audio data that improves the accuracy of predictive compensation for packet loss audio.

Description

Technical field [0001] The present application relates to the field of computer technology, and more particularly to an audio processing method, related equipment, storage media, and program products. Background technique [0002] With the continuous development of computer network technology, the audio data typically packet packets during transmission, resulting in partial audio data in the transmission audio cannot be received by the receiving end, which affects the user's listening Experience. The method of compensation recovery of the current packet loss audio is usually used to use the self-return iterative prediction method, that is, the method of sequentially predicted the next sampling point based on the previous sampling point, and due to the process of iterative prediction, error It will continue to accumulate, so how to improve the accuracy of the audio data obtained after the prediction compensation of the packet-lost audio has become the current research hotspot. In...
