摘要：
This piper presents the implementation of MPEG-2 layer 1 audio coding and decoding system on a general purpose fixed-point DSP chip. A modified coding algorithm th:lt alleviates the edge effect is described. This scheme encodes data in frames adjacent to the current frame so that data is closely correlated between frames. Results from the DSP realtime implementation are examined. Bit-rates from 74 to 138 kbps for the signals tested are attainable with transparent quality signal reconstruction.
