| 摘 要： | 声音信号的存储与传输,从模拟信号到数字信号经历了迅速的发展。随着多媒体处理技术的发展,数字音频压缩编码技术得到了广泛的应用。运动图像专家组—MPEG（Moving Picture Expert Group）,该组织自1988年以来制定了一系列国际标准,其中MPEG-1、MPEG-2已为人们所熟知。从1999年开始,他们陆续制定了新的MPEG标准：MPEG-4、MPEG-7和MPEG-21,对音频技术的发展产生了深远的影响。

| Abstract: | The storage and transmission for audio signal has developed from analog signal to digital signal.As digital audio coding technology has been a wide range of applications.The MPEG（Moving Picture Expert Group） has developed a series of international standards since 1988.Among them,MPEG-1 and MPEG-2 are well known.Since 1999 new MPEG Standards like MPEG-4,MPEG-7 and MPEG-21 have been formulated,which produced far-reaching effect on audio technology. |
