[PD] cq2midi – Polyphonic MIDI notes from audio

[Thomas Grill]

Hi all,
I just added the cq2midi project to my list of software publications.
This project tries to analyze a stream of digital audio data into MIDI notes. It does so not from a traditional musicological perspective (f0 analysis or the likes), but rather in a raw fashion, so that “all” predominant frequencies of the spectrum at a certain time are interpreted as MIDI notes. Some filtering options are available to reduce noise.
I originally designed this software to realize the composition luscinia megarhynchos for computer-controlled carillon, premiered at the Pure Data convention 2011 in Weimar.
