MPEG audio layer3compression algorithm is a high efficiency and HI-FI compression coding of digital audio specified by ISO-11172standard.This paper analyses the key technologies used in MP3,such as subband filter,psychoacoustical model and dynamic noise allocation.A new fast algo-rithm is proposed for sub-band analysis method of MPEG for real time and it is implemented using one digital signal processor TMS320VC5402.[
