ITU-T speech code
- ITU-T音频格式编解码代码，包括：G.711 G.721 G.723, 其中G723还支持16kbit/s 24kbit/s 40kbit/s几种码率。g72x.h g711.h是共用的头文件。-These are ITU-T speech codecs,include G.711 G.721 G.723,and G.723 also supports 16kbit/s 24kbit/s 40kbit/s. g72x.h and g711.h are common head files.
基于ACELP算法的编解码
- 本程序是基于ACELP算法编写的语音编解码程序，里面有两个程序例子，一个是编码程序，另一个是解码程序。-This is a speech codec based on ACELP algorithm,there are two examples in it,one is the encoder,anther is decoder.
lame3.97_06.25
- LAME无疑是目前最优秀的MP3编码软件，与传统的MP3编码器相比，它能够更好地利用人耳遮蔽效应，并且支持VBR（可变码率）以及joint stero（联合立体声）技术，从而在一定的压缩比达到了更好的听音效果。所以，使用LAME编码的MP3具有细节丰富、高频失真小的优点。这是最新发布的4.0 Alpha版本，编码速度有了非常大的改善，但是音质效果却并没有提高的迹象。推荐使用VBR-0方式编码。 HTTP：//WWW.PSPHOME.NET 里面有个：工具软件
