安装方法
解压tar.gz包
tar cgvf soundtouch-1.9.2.tar.gz
进入解压目录
cd soundtouch
执行安装引导命令，用于生成configure和Make文件
./bootstrap
安装
./configure --prefix=/usr/local/soundtouch-1.9.2
make & make install
添加MP3组件
cd /usr/local/soundtouch-1.9.2/bin
将soundstretch4Lame放入该目录下（该文件是一个shell脚本，用于处理mp3文件。soundTouch工具本身并不支持mp3的编码，需要使用LAME工具对mp3文件进行解码和编码操作）。
chmod +x soundstretch4Lame
验证
[root@home ~]# soundstretch

This program is subject to (L)GPL license. Run "soundstretch -license" for
more information.
This application processes WAV audio files by modifying the sound tempo,
pitch and playback rate properties independently from each other.
Usage :
soundstretch infilename outfilename [switches]
To use standard input/output pipes, give 'stdin' and 'stdout' as filenames.
Available switches are:
-tempo=n : Change sound tempo by n percents (n=-95..+5000 %)
-pitch=n : Change sound pitch by n semitones (n=-60..+60 semitones)
-rate=n : Change sound rate by n percents (n=-95..+5000 %)
-bpm=n : Detect the BPM rate of sound and adjust tempo to meet 'n' BPMs.
If '=n' is omitted, just detects the BPM rate.
-quick : Use quicker tempo change algorithm (gain speed, lose quality)
-naa : Don't use anti-alias filtering (gain speed, lose quality)
-speech : Tune algorithm for speech processing (default is for music)
-license : Display the program license text (LGPL)
