One Step further towards Diplom Thesis

While doing yet again a search for companies or institutes, i.e. a attendant, possibly related to what I’m looking for (automated music similarity analysis) I got one big step forward finding projects at the Fraunhofer IDMT (Institute Digital Media Technologies) that sound really interesting. What I’m interested in is doing some sort of wave form analysis and find different characteristics, different descriptive measures that make two music pieces “sound similar” independent of genre, same artist or whatever and those that make two other pieces different. Most interesting would be to derive them from how we humans would decide it which, of course, is not always deterministic, i.e. fuzzy. The long term dream would be to have an automate find the right music for a given emotional atmosphere, e.g. candle lite dinner, BBQ, reception event…

  • SoundsLike — Sounds like it comes close to what I’m interested in; derived from AudioID fingerprinting mechanism.
  • GenreID — more the category based approach similar to acoustic fingerprinting. Still interesting, though.
  • Query by Humming — Finding music tracks by humming the characteristic melody. But what exactly is characteristic to a certain track?
  • Semantic HiFi — interesting project; combines multiple tools to have the stereo generate personalized playlists on demand via call by voice, interacts with other media devices. Reads very promising. The project itself went from 2003-2006. And what’s really interesting is a cooperation with, among others, the University of Pompeu Fabra, Barcelona, Spain.
    I also could imagine automated adjustment of volume level by sound level in the room if actually it’s wise and no feedback effekt takes place, e.g. at a cockail party: conversation louder -> music louder -> conversation louder…
  • Retrieval and Recommendation Tools — just the attempt I’m looking for.

I also stumbled upon news that the mp3 format has been enhanced to encode surround sound information while only enlarging file size by about 10% (see also mpegsurround.com). And secondly an attempt to use P2P to legally ship music content and to utilize it to encourage people to by the better quality version called Freebies.
