From this post

you'll need:

http://github.com/bram/freesound/blob/34606cd534ce7b3bbb59ba1e4c8fbdcb85d4e863/freesound/utils/audioprocessing/processing.py http://github.com/bram/freesound/blob/34606cd534ce7b3bbb59ba1e4c8fbdcb85d4e863/freesound/utils/audioprocessing/wav2png.py

and then also install numpy, PIL and scikits.audiolab (which needs libsndfile).

you can remove any reference to simplejson, you don't need it for wav2png.

You can find the full source code to generate these images in the nightingale repository ( http://github.com/bram/freesound/tree/master ), in particular look in the directory /freesound/utils/audioprocessing/
