Getting and Using Vamp Plugins / Re: Get the Chord sequence from a song

« on: December 03, 2010, 09:22:38 »

Hi Frank,

So, now there's actually a Vamp plugin that does that: Chordino 0.2, available at http://isophonics.net/nnls-chroma

Should be very easy to install. An installation video for Mac OS is available here:

All the best,

Host Forum: Sonic Visualiser / Win an iPod in the OMRAS2 Vamp/Vampy Contest

« on: October 19, 2009, 16:56:14 »

Dear all,

We are proud to announce the first OMRAS2 Vamp/VamPy Plugin Contest, aimed at Music IR researchers around the world. We develop the free and open software Sonic Visualiser (http://www.sonicvisualiser.org/) and other Vamp hosts that give Vamp plugins immediate world-wide exposure. Our Vamp hosts run on Windows, Mac and Linux -- out of the box.

We believe that the Vamp interface can help MIR researchers exchange their algorithms and use their results, e.g. for visualisation in Sonic Visualiser or Audacity, or automate the extraction with the batch processing Vamp host Sonic Annotator. That's why we want to encourage you to add to the growing set of available Vamp plugins (http://www.vamp-plugins.org/download.html).

That's also why, additional to all the benefits of having your own Vamp/VamPy plugin, you can now win an iPod!

For more information on why it's the thing to do, and how to do it, visit

   http://omras2.org/VampContest

Or, if you come to the ISMIR conference in Kobe, why not chat about it with me or one of the other OMRAS2 people!

Hi Frank,

Bad news first: There is currently no vamp plugin for chord extraction that I am aware of. That's a bit of a shame, especially since I am actually doing research on chord extraction from audio. But my stuff generally too complicated for me to try and rewrite it all in C++ for the Vamp plugin.

Secondly: Please be aware that the key extraction plugin is no chord extraction plugin. Keys describe the tonality of a chunk of music, which usually contains many chords, so there is quite some difference between the two concepts. Consequently, you cannot expect the key extractor to give you good chord estimates (or indeed good beat estimates ).

There may be hope though, since I know that we (Centre for Digital Music at Queen Mary) are going to release Vampy soon (should be a matter of hours or a few days), and I could relatively easily write a Vampy plugin for you for a very basic chord estimation. So, watch the news about Vampy and make it work on your system. Then tell me, and I'm sure we can come up with something.

Best,
Matthias
