I reinstall it on a different machine i got the same error with the nsdfile no warning anymore with audiolab .
I followed these points:


audiolab requires the following softwares:

  • a python interpreter.
  • libsndfile
  • numpy (any version >= 1.2 should work).
  • setuptools

On Ubuntu, you can install the dependencies as follow:

sudo apt-get install python-dev python-numpy python-setuptools libsndfile-dev


Audiolab can optionally install audio backends. For now, only alsa (Linux) and Core Audio (Mac OS X) are supported. On Linux, you need alsa headers for this to work; on Ubuntu, you can install them with the following command:

sudo apt-get install libasound2-dev

For Mac OS X, you need the CoreAudio framework, available on the Apple website.


For unix users, if libsndfile is installed in standart location (eg /usr/lib, /usr/local/lib), the installer should be able to find them automatically, and you only need to do a “python setup.py install”

Concerning the eventual site.cfg file i have no idea what to do with this it might be the problem maybe you can give advice?

Thank you

How did you install it ? Your installation looks bogus (if you build
it by yourself, please give the *exact* instructions you used)
