28 May 2011 by dasblinkenlight

The problem is somewhat similar to DTMF recognition (figuring out "two-sound chords" produced by telephone buttons). A very efficient Goertzel Algorithm[^] is used rather widely for that. It may or may not help you solve the problem at hand, but it's definitely worth giving a try. Good luck!

1 Jun 2011 by Nyx.Carpenter

Musical phenomenons - notes of the frequency being played may contain occurrences of the note's higher octaves. E.G. A440 (440Hz) may contain instances of A5 (880Hz) and A6 (1760Hz) etc. I've found this is more likely the lower the note gets.

3 Jul 2011 by Albert Holguin

This is an interesting project, but I can tell you you'll end up having a really hard time identifying chords, since you'll end up not only with a combination of notes, but a variety of byproduct frequencies. You're bound to find all sorts of interesting things, good luck!
