[PD] chroma

[Jeppi Jeppi]

Just to clarify,A "chroma feature" is just an spectrogram warped into the 12-semitone ET pitch class space

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
