Advanced chroma features

http://www.mpi-inf.mpg.de/resources/MIR/chromatoolbox/

Implementation of novel chroma features proposed in the following articles:

• Audio matching via chroma-based statistical features.  ISMIR 2005
• Making chroma features more robust to timbre changes.   ICASSP 2009
• Towards timbre-invariant audio features for harmony-based music. TASLP 2010

An article described this toolbox is in the proceedings of ISMIR this year

• Chroma Toolbox: MATLAB Implementations for Extracting Variants of Chroma-Based Audio Features.  ISMIR 2011

The author of this toolbox (Meinard Muller) will give a tutorial on "Audio Content-based Music Retrieval," with an MTG researcher, Joan Serra.
