Decided to give this project an official name, Spectrotune.
Updated and beautified the interface. Added octave filters, Pitch Class Profiling, FFT bin distance weighting, FFT Smoothing, FFT Envelopes and Equalization, amongst other things. The detection is a great deal more accurate tho I still have a lot of work to do before im happy with it.
The Song is a MAAD - Sanitarium (Metallica Cover), its a chip tune remix. Minimal and not a lot in the way to clutter up my detection.
What you are hearing is the recorded MIDI output from the scanned wav file.
