This is 3 parallel FM tracks versus the backstreet boys.

The track w/o the backstreet boys is here:

Mostitch tries to interpret the audio by running metrics on the input audio (backstreet boys) and then matches it to the closest audio from the fm synthesizer. Then it reports the index of the best match in the synthesizer. This best match aligns with a set of parameters that we feed back into the original synthesizer.

To give you some idea of the roundabout path we take here’s an example of how everything starts:

python fm/fmout.wav | perl fm/ fm/map.dump | csound -L stdin -o devaudio -+rtaudio=jack -dm6 ./fm/fm.orc ./fm/fmlive.sco

This version is 3 bands of FM synthesis stitched together with some hard stereo panning.
