摘要
本文介绍了ＩＳＯ／ＭＰＥＧ音频压缩编解ｌａｙｅｒⅢ规定的６４ｋｂｐｓ编解码标准，及其ＤＳＰ实现。作者据此标准完成了计算机Ｃ语言模拟仿真，获得满意的重建音乐信号质量。且对解码器的ＤＳＰ实现进行了研究，通过ＴＭＳ３２０Ｃ５４８模拟器对解码器的仿真，取得了与Ｃ语言一致的结果。
In this paper,the ISO/MPEG Audio Layer Ⅲ digital audio compression scheme coding at 64 kbit/s is introduced,including the rcalization of the decoder.First,the author of this paper has implemented C language simulation according the algorithm and got the satisfying quality of the reconstructed music signal.After the estimation of operation steps,simulation of decoder finished by TMS320C548 simulator is presented.The result is the same as that of the C language simulation.
