[0002] At present, with the wide application of automation technology and intelligent technology in daily life, industrial production and other fields, using voice to directly control equipment has gradually become one of the important operation methods of intelligent control systems. In order to meet the long-distance audio signal To meet the needs of transmission operations, it is often necessary to encode and compile the audio into data files that can be recognized by the communication network system before transmission. In response to this need, the current compiling method is often to compress the content of the audio file, and then compress the content of the audio file. The compressed file is directly compiled into a data signal recognizable by the communication network system for transmission. Although it can meet the needs of audio model transmission, on the one hand, the work efficiency of the audio signal encoding operation is relatively low. On the other hand, the audio signal is encoded and converted. It often leads to the decline of audio quality, and even distortion in severe cases. At the same time, when restoring audio signals, the conversion form of audio models cannot be flexibly adjusted according to the needs of use. Therefore, the currently commonly used audio coding methods cannot effectively satisfy In view of the current situation, it is urgent to develop a new audio coding system to meet the needs of actual use.
