Audiolab是一个使用numpy数组的音频文件IO的python包。它支持许多不同的音频格式，包括wav，aiff，au，flac，ogg，htk。它还支持输出到音频设备（仅限Mac OS X和Linux）。
为简单起见，提供了类似matlab的API，用于简单的导入/导出; 还提供更完整的API。

提示需要安装sndfile。

下载audiolab：

# wget https://files.pythonhosted.org/packages/b0/d8/d9babf3e4fa3ac8094e1783415bf60015a696779f4da4c70ae6141aa5e3a/scikits.audiolab-0.11.0.tar.gz

解压后通过python3 setup.py install安装出错，也是提示没有找到sndfile

下载libsndfile

#wget http://www.mega-nerd.com/libsndfile/files/libsndfile-1.0.28.tar.gz

解压并安装：

# tar xzvf libsndfile-1.0.28.tar.gz
# cd libsndfile-1.0.28
# .configure
# make
# make install

centos下的site.cfg文件：

[root@localhost audiolab]# cat site.cfg
[sndfile]
include_dirs = /usr/local/include
library_dirs = /usr/local/lib/
sndfile_libs = sndfile

Ubuntu下的site.cfg文件：

[sndfile]
include_dirs = /usr/include
library_dirs = /usr/lib/x86_64-linux-gnu/
sndfile_libs = sndfile

在audiolab目录下，再次执行python setup.py install 可以了。
