I found a good .wav file of an evil laugh,
Other songs that have been converted over (see this for instance) must have been much larger than what I'm working with?
No that is not just a pure sample. That is using the Squawk as a synthesiser to generate the note but the actual notes are sequenced by a list of data from the program.
but what if I use squawk's converter to convert my sound file into a data list in the program?
Squawk requires your ProTracker files to be converted into Squawk melodies.Melodies come in two flavors:As data you put in your sketch to download with your code.sketches/Squawk_playerAs a file on an SD card connected to your Arduino.sketches/SquawkSD_playerBoth formats can be generated by converter in the convert/ directory.
