Genetic algorithms for automatic calibration of classic and modified FM sound synthesis models.

ga-fm

Classic and Modified FM (modFM) are sound synthesis techniques that can be used to generate harmonic instrument sounds.

ga-fm is a genetic algorithm (GA) using a fitness function based on harmonics analysis that is able to automatize the calibration of FM synthesis models for the reconstruction of harmonic instrument tones.

##Dependencies ga-fm requires some MATLAB toolboxes:

• Global optimization toolbox
• Parallel Computing Toolbox (to speed up the evolution)

##Getting start

• Put the WAV sound files you want to reconstruct in the sounds folder.
• Run matlabpool (start Parallel Computing Toolbox).
• Run scriptExpClassicFM.m (resp. scripExpModFM.m) to reconstruct your sounds using Classic FM (resp. ModFM).
• The results will be stored in classic.mat (resp. mod.mat) and the synthesized sounds written in the current folder.

##Limitations

• Neither the MATLAB code nor the GA parameters are optimized so be patient :).
• Limit yourself to short target sounds (around 2 seconds long).

##More info

• More information about the implementation can be find in this paper taken from the proceedings of SMC2012.
• The slides of the presentation are on slideshare.
• Some results are available to listen here.
