Layer 1 用于数字压缩磁带（DCC），这个产品在几年以后停用了；Layer 2 用于音频广播，以及作为 Video CD（VCD）的音频组件使用；第三层（MP3）就不需要特别介绍了。MP3 在接下来的 MPEG-2 中进行修订后，它在听感上与原 CD 信号几乎没有差异的同时，提供 128 kbit/s 的码率。这与原本 CD 信号 1.44 Mbit...

MPEG-1音频分三层,就是MPEG-1 Layer I, II, III,其中第三层协议也就是MPEG- 1 Layer 3,简称MP3。MP3目前已经成为广泛流传的音频压缩技术。 MPEG-1有下面几个部分: Part 1:系统; Part 2:视频; Part 3:音频;定义level1,level2,level3,并在MPEG-2中定义了扩展。
