This is a nice chord-extraction plugin which works in Audacity -- may be of some interest, I hope. Chris ---------- Forwarded message ---------- From: Chris Cannam <chr...@el...> Date: Thu, Oct 28, 2010 at 1:37 PM Subject: Chordino and NNLS Chroma -- new Vamp plugins To: mus...@li... We're happy to announce the first release of an new open source Vamp plugin (http://vamp-plugins.org) library for harmony and chord extraction, based mainly on Matthias Mauch's PhD research in the EPSRC-funded OMRAS2 Project at the Centre for Digital Music, Queen Mary University of London. The library contains the Chordino, NNLS Chroma and Tuning plugins and should run in all Vamp hosts (e.g. Sonic Visualiser, Audacity, Sonic Annotator). The main features are: * Chordino: a simple, no frills chord transcription method based on NNLS Chroma features, * NNLS Chroma: high-quality chroma features for harmony visualisation or further processing, * Tuning: an estimate of the 'concert pitch' tuning. The NNLS Chroma plugin was the feature extractor used for Matthias' MIREX submissions this year. The plugin implementation is by Matthias Mauch and Chris Cannam. The code is published under the GNU General Public License.
