How to use the documentation

Documentation is available inline as docstrings provided within the code. In time, it is our intention to host a Sphynx-like online reference to facilitate ease of use.

Examples provided assume that each module has been imported as its first characters in uppercase:

>>> import marlib.audiofile as AF
>>> import marlib.timefreq as TF
    ...

...where code snippets are indicated by three greater-than signs.

Use the built-in help function to view a function's docstring:

>>> help(TF.mel)

Available subpackages

audiofile timefreq signal utils

Dependencies

This package builds upon freely available Python libraries at various stages of maturity:

  • NumPy: Numerical Computing in Python
  • SciPy: Scientific Computing in Python

Additionally, this library takes advantage of SoX, a command line utility for non-wave file support and audio file conversion. If you do not currently have SoX, it can be obtained here:

http://sox.sourceforge.net

SoX functionality is currently supported under Unix-like OS's only, (sorry, Windows). However, extending this library should be straightforward if necessary. Note that SoX is required only for file conversions and non-wave file formats, so - while strongly encouraged - SoX is not truly mandatory.
