I've added the G1C implementation which I described in my
thesis
and which did well in the
MIREX'06 audio similarity evaluation. More comments on this can found
here.

Thanks to helpful comments from Charles Walker and Abhinav Singh I fixed the broken link to emd.zip and
updated ma_simple_eval (adding a little more feedback and error checks).
There might be an issue with ma_fc (if you get a strange error pointing to line 114 in ma_fc that
might be it). Unfortunately, I can't reproduce it and I don't have time to look into it right now. I'm guessing that it happens when there is
only one item assigned to a cluster (something Mark Godfrey noticed recently).
If that happens you could try using longer audio files (e.g. at least 60 seconds) and fewer clusters.

MA toolbox website moved here.
A bug reported by Mark T. Godfrey in ma_fc was fixed. The bug effected kmeans clustering. Instead of selecting the best cluster model from 5 different runs each with a different random initializations, only one run was used.

Thanks to Adam Berenzweig (ma_cms) and Klaus Seyerlehner (ma_mfcc & ma_fp) a number of bugs were fixed. The one in ma_cms was a major one which effected the KL computations.
The Music Analysis (MA) toolbox is a collection of functions for Matlab. It contains functions to
analyze music (audio) and compute similarities.
The type of similarity computed can be used to, e.g., generate playlists or organize music collections.
For details see the
documentation.
The MA Toolbox can be redistributed and/or modified under the terms of the
GNU General Public License as published by the
Free Software Foundation. Either version 2, or any later version apply.
For full functionality the MA toolbox requires the
NETLAB toolbox and
the
EMD functions by Y. Rubner to be installed.
(See
download section for details.)
This toolbox will be maintained on a very irregular basis. Any contributions are very welcome!
