Audio Video Coding Standard(AVS) is a second- generation source coding standard and the first standard for audio and video coding in China with independent intellectual property rights.Its performance has reached the international standard.Its coding efficiency is 2 to 3 times greater than that of MPEG-2.This technical solution is more simple,and it can greatly save channel resource.After more than ten years development,AVS has achieved great success.The latest version of the AVS audio coding standard is ongoing and mainly aims at the increasing demand for low bitrate and high quality audio services.The paper reviews the history and recent development of AVS audio coding standard in terms of basic features,key techniques and performance.Finally,the future development of AVS audio coding standard is discussed.
