MP3
下面是MP3编码类型的详细介绍：
1、音乐格式——将音源信号按照不同的协议进行录制和压缩进行处理后，形成的档案文件格式。音乐格式分无损压缩格式（如CD、WAVE等格式）、有损压缩格式（如MP3、RM、WMA）和一些专用格式（如MIDI）。 本文主要是对音频格式分析。
2、位速——每秒钟声音流的字节数，也叫码率、码速、线速等。单位是Kbps或Kb/s,注意这里使用的"b"是bit。通常人们“位速”又叫音效水平，一般位速高代表音效水平较好。
3、档案容量——是指存储在记录器（如磁盘、光盘等）上的占用空间容量。一般用*MB表示，本文使用的"B"是byt单位; 1byt=8bit。
4、声音文件——是音乐、歌曲、朗诵等文件的总称。为行文直观，本文也用音乐、歌曲的来泛代声音文件。
首先我们来认识下MP3这种现下最流行的音频格式:
MP3 是利用 MPEG Audio Layer 3 的技术，将声音用 1:10 甚至 1:12 的压缩率，变成容量较小的文件，但是在人耳听起来，却没有什么不同。当然这是一种失真压缩，就像图形文件 JPG 一样，因为失真压缩，所以可以压得很多，也可以调整压缩比率，压得越多失真也越多。
现在最流行的几款MP3编码方式:
VBR（Variable Bitrate）动态比特率。也就是没有固定的比特率，压缩软件在压缩时根据音频数据即时确定使用什么比特率，这是以质量为前提兼顾文件大小的方式，推荐编码模式；
