Problems solved by technology
This encoding method can compress the code stream to a very small size, but it is difficult to restore the uncompressed complete code stream from the compressed code stream, so when the complete code stream is needed, the complete code stream can only be retransmitted, which brings waste of some resources

The invention provides an audio code stream compression method and device based on deep learning, and relates to the technical field of audio data processing. According to the method, code streams compressed by using a deep learning algorithm are subjected to reverse restoration, and the restoration degrees of the code streams before and after the compression and restoration of the deep learning algorithm are compared; performing optimization iteration on compression and reduction of the deep learning algorithm according to the reduction degree until the reduction degree reaches a preset threshold value after all the audio code streams are compressed and reduced by the deep learning algorithm, and recording the number of times of optimization iteration in the optimization iteration process; and judging whether the deep learning algorithm needs to be replaced or not according to the number of optimization iterations, and further performing compression processing on the audio code stream by using the deep learning algorithm obtained by judgment. Therefore, according to the embodiment of the invention, the uncompressed code stream can be restored through the trained deep learning algorithm framework, so that the condition of retransmission when the code stream with complete quality is needed is omitted, and resources are saved.
Description
technical field [0001] The present application relates to the technical field of audio data processing, and in particular to a deep learning-based audio stream compression method and device. Background technique [0002] The current audio compression method is mainly based on the shielding effect and the hearing range of the human ear to remove the shielded sound and the sound that the human ear cannot hear. This encoding method can compress the code stream to a very small size, but it is difficult to restore the uncompressed complete code stream from the compressed code stream, so when the complete code stream is needed, the complete code stream can only be retransmitted, which brings A waste of some resources. Therefore, it is urgent to solve this technical problem. Contents of the invention [0003] In view of the above problems, this application is proposed to provide a deep learning-based audio stream compression method and device that overcomes the above problems o...
