I’ve been interested in learning more about music information retrieval systems. here are a few resources i’ve been looking at:
*There’s a Google Tech Talk called “from sound synthesis to sound retrieval and back” by Xavier Serra of Music Technology Group at the University of Pompeu Fabra in Barcelona. Serra has quite a few projects in development from sound retrieval systems that look for similar harmonic structure or rhythm to developing tangible interfaces. He also demonstrates the “reacTable” which is an instrument that Bjork used on her Volta tour.
Some really cool things happening with MIR. With signal processing, users can access more than just what libraries normally catalogue (info attached to the physical format, digital info like text, digital sound data) and go further up the symantic ladder to obtain info like pitch, duration, timbre, intensity and further up the ladder as high as type of music, key of music, melody within a polyphonic piece, etc.
*“Information Retrieval for Music and Motion” by Meinard Muller is one of those good Springer books. I’m just getting into it now, but it looks pretty comprehensive. Two major parts: part 1 Analysis and retrieval techniques for music data; and part 2 Analysis and retrieval techniques for motion data.
