Abstract

The present invention provides an audio compression method, audio decompression method and device, the method comprising: segmenting audio data in a preset encoding format to obtain N audio segments; inputting each of the audio segments into a pre-trained The audio compression network obtains the audio compression feature matrix and the audio timing feature vector corresponding to each of the audio clips, wherein the audio compression network includes a convolutional neural network with residuals and a deep recurrent neural network; The audio compression feature matrix corresponding to the audio segment is concatenated with the audio time-series feature vector to obtain audio compression data. Through the audio compression method provided by the invention, the stability of the audio compression ratio can be improved, and the streaming compression of audio clips can be realized, which is convenient for the streaming transmission of compressed audio.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio compression method, an audio decompression method and a device. Background technique [0002] At present, audio compression is usually implemented based on structured coding, for example, mp3 (Moving PictureExperts Group Audio Layer III, moving picture expert compression standard audio level 3), however, the compression ratio of this audio compression method is the same as that of the audio data to be compressed The correlation of audio data with different content characteristics is relatively large, and the compression ratio of audio data with different content characteristics is quite different. For example, for audio data with small content changes, the compression ratio is large, while for audio data with rich content changes, the compression ratio is small . [0003] It can be seen that the existing audio compression methods based on structured coding have...
