it would be great if you could clarify your expressions "chroma" and "stream-based".
(in Pd we are dealing with loads of totally different "streamed" media that have "chroma")

Just to clarify,A "chroma feature" is just an spectrogram warped into the 12-semitone ET pitch class space
http://labrosa.ee.columbia.edu/matlab/chroma-ansyn/ So for each audio frame you get a vector of 12 values. That's useful for chord and tonality recognition. By stream based I just meant realtime. Not file-based analysis.Josep
