摘要：
DRA (Dynamic Resolution Algorithm) is referred to specification for multi-channel digital audio coding technology which was issued as a Chinese national standard in 2008. A low bit rate audio coding algorithm based on DRA is presented in the paper with a significant improvement in the coding efficiency of DRA at 32kbps/stereo by BWE (BandWidth Extension) and PS (Parametric Stereo) tools, and it was adopted as the source coding of CDR (Chinese Digital Radio).
