From the developer:
Spectrotune is a Processing application that scans a polyphonic audio source (in WAV, MP3, etc. formats), performs pitch detection, and outputs to MIDI. The program helps you attenuate low frequencies and amplify high frequencies. It can narrow the spectrum to the octaves you are interested in recording and route each octave to its own MIDI channel.
