Several python libraries implement discrete wavelet transforms. However, none of them, or at least none that I know, is aimed at scientific use. This module started as translation of the wmtsa Matlab toolbox (http://www.atmos.washington.edu/~wmtsa/), so most naming conventions and most of the code structure follows their choices. The code uses a mix of python and cython for improved performance.
The code reflects my needs and preferences, but contributions from others are welcome.
The code is still evolving, so downloading the latest version from svn is always the best option.
The code has to some extent been tested, but bugs are to be expected.
