好的，所以我想用Python进行一些基本的信号处理，并找到了一个名为的出色库scikits.audiolab。

在任何地方都找不到PPA。那好吧。我以为我可以简单地将其安装在我的Ubuntu Oneiric服务器上

sudo aptitude install libsndfile-dev

接着

sudo easy_install scikits.audiolab

然而，这失败了

error: sndfile (http://www.mega-nerd.com/libsndfile/) library not found.
Directories to search for the libraries can be specified in the
site.cfg file, in section [sndfile].

WTF？好的，查询libsndfile1-dev文件列表：

japsu@helios ~ $ apt-file list libsndfile1-dev
libsndfile1-dev: /usr/include/sndfile.h
libsndfile1-dev: /usr/include/sndfile.hh
libsndfile1-dev: /usr/lib/x86_64-linux-gnu/libsndfile.a
libsndfile1-dev: /usr/lib/x86_64-linux-gnu/libsndfile.la
libsndfile1-dev: /usr/lib/x86_64-linux-gnu/libsndfile.so
libsndfile1-dev: /usr/lib/x86_64-linux-gnu/pkgconfig/sndfile.pc
[...]

很奇怪，图书馆会进入非标准图书馆目录吗？愚蠢的打包者。

那好吧。下载的源代码scikits.audiolab，这样写site.cfg：

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

现在python setup.py build并sudo setup.py install成功完成。

接下来，启动一个Python shell，尝试执行以下操作from scikits.audiolab import sndfile：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "scikits/audiolab/__init__.py", line 25, in <module>
    from pysndfile import formatinfo, sndfile
  File "scikits/audiolab/pysndfile/__init__.py", line 1, in <module>
    from _sndfile import Sndfile, Format, available_file_formats, \
ImportError: No module named _sndfile

但：

>> sys.path
['',
 '/usr/bin',
 '/usr/lib/pymodules/python2.7',
 '/usr/local/lib/python2.7/dist-packages/scikits.audiolab-0.11.0-py2.7-linux-x86_64.egg',
 '/usr/lib/python2.7',
 '/usr/lib/python2.7/plat-linux2',

 '/usr/lib/python2.7/dist-packages',
 '/usr/lib/python2.7/dist-packages/IPython/Extensions',
 u'/home/japsu/.ipython']

并_sndfile.so在找到/usr/local/lib/python2.7/dist- packages/scikits.audiolab-0.11.0-py2.7-linux-x86_64.egg/scikits/audiolab/pysndfile/_sndfile.so。

所以，我的问题是

1. WTF正在进行吗？python为什么找不到_sndfile.so？
2. 有人scikits.audiolab在2011年的Linux发行版中成功使用了2011年吗？你是怎么做到的？
3. 是否有任何好的替代库可以将巨大的（例如10 GB / 8小时）WAV文件逐块读取到NumPy中？
