Audio files, FFT and OpenCL...

Recommended Posts


I would like to do some work with audio file analysis and find chops very alien, limited and annoying, so wonder what would be involved if I'd want to do this without them.

The elements of what I have in mind would be:

  • Open a stereo wave file as raw data somehow.
  • Analyse it using a FFT.
  • The latter maybe in openCL for speed.
  • Create geometry from the results.

I'm looking for a direction on how to best tackle this in Houdini with the least unneeded overhead possible, so using existing libraries/examples would be preferred, adapting them to what I need...

Thanks for any pointers!
