Abstract

The present invention relates to an audio quality recovery system based on GAN. The system comprises a model sharing block module, a generation network model module, a distinguishing network module and a sequence recombination module; the model sharing block module is mainly used to perform feature extraction for time-domain signals without frequency domain processing due to avoidance of information loss and extract the features to a high-level unit; the generation network model module employs a high-level extraction unit to perform analysis and reconfiguration; the distinguishing network module is configured to continuously perform adversarial training with the generation network model to continuously improve a generation effect; and the sequence recombination module analyzes the sequenceweighing recombination of the final generation output by the network. The audio quality recovery system based on the GAN can generate more vivid audio signals.

Description

technical field [0001] The invention relates to the technical field of audio signal restoration and processing, in particular to a GAN-based audio sound quality restoration system. Background technique [0002] In order to facilitate network transmission and local storage, a large number of audio files need to be compressed, but the corresponding sound quality will be sacrificed while the storage space is reduced. In order to effectively utilize network resources, music platforms often provide different music qualities. The resources are not the most efficient. Audio restoration technology can be used to restore audio resources with relatively high compression, thereby avoiding separate storage or decompression processes on the server and client. Lossy compression is used not only in MP3 players and PCs, but also in video playback devices, digital TV, Internet streaming, satellite radio, and more. Because lossy compression discards some unimportant parts, the compression ra...
