摘要
Audio Video coding Standard (A VS) is the latest audio and video coding standard of China. A VS Part 7 (also known as AVS-M) audio coding tools target mobility applications Where perceptual weighting is of great importance for subjective performance. This paper first briefly introduces the general concept of perceptual weighting. Then a candidate perceptual weighting scheme is proposed and testified on A VS-M audio coder. Further optimization on the candidate is illustrated thereafter. Subjective results of the optimized scheme provide hybrid audio quality comparable to the 3GPP AMR-WB+.
