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 βallβ 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.
