Audiolab is a python package to read/write audio files from numpy arrays.
Matlab have functions such as wavread, wavwrite, soundsc, etc... The goal of
audiolab is to give those capabilities to the `scipy`_ environment by wrapping
the excellent library `libsndfile`_ from <NAME>. Audiolab supports
all format supported by libsndfile, including wav, aiff, ircam, flac (an
open source lossless compressed format) and ogg vorbis (an open source
compressed format - simlar to MP3 without the license issues); see `here
<http://www.mega-nerd.com/libsndfile/#Features">`_ for a complete list.

The main features of audiolab are:

        * reading all formats supported by sndfile directly into numpy arrays.
        * writing all formats supported by sndfile directly from numpy arrays.
        * A matlab-like API (ala wavread) for some file formats. Wav, aiff,
          flac, au, and ogg formats are supported.
        * A play function to output data from numpy array into the sound device
          of your computer (Only ALSA for linux and CoreAudio for Mac OS X is
          implemented ATM).

**Note**: The exact features and supported file format depend on your
installed version of libsndfile and your platform. Audio playback is only
implemented for Linux and Mac OS X.

**Note**: The library is still in flux: the API can still change before the
1.0 version. That baing said, the version 0.10 was a major change, and I
don't expect any more major changes from now on.

**Note**: The online version of this document is not always up to date. The
pdf included in the package is the reference, and always in sync with the
package. If something does not work, please refer first to the pdf included in
the package.
