Abstract: MPEG-1 audio layer III is widely used due to its high compressing ratio and excellent coding quality. In this paper a DSP based MPEG-1Audio Layer III real-time CODEC is presented. The system adopts high performance DSP and flexible audio interface, optimizes the algorithm of MP3 and realizes the encoding and decoding process in real time .
