I have just released a new version of Spectrotune after nearly a year of inactivity.

Spectrotune attempts to detect pitches of an audio source file (wav format) and send output to MIDI.

In this demostration, spectrotune is analyzing the song Computer Liebe by Kraftwerk and sending MIDI output to Propellerheads reason, seperating octaves between a pad, a violin, and piano sampler synths. You can record the incoming MIDI channels, clean up, and then work into your own remixes and covers.

I hope you enjoy this project as much as I have enjoyed working on it.

New features:

* Now runs as a standalone .app on os x no need to install processing.

* MIDI octave channel segmenting - segment octaves by channel so each octave can be sent to its own midi synth (the video demostates segmenting octaves between a pad, a violin, and a piano)

* Seek Slider - you can now seek and pause the audio track.

* Scale Lock - when spectrotune loads a wav file it will first precomute a scale of most used notes. When scale lock is turned on it will attempt to snap detected pitches to the notes in the scale.

* Harmonics Filter - allow you to filter out harmonic frequencies that trigger peak detection.

* Balance - allows you to adjust balance to stereo channel you wish peak detection to be skewed towards.

* File Browser
