Inspired by wav2json, but just a little different.

note: py-wav2json depends on NumPy and SciPy

python wav2json.py -i track.wav

will create a JSON file containing a single linearly interpolated approximation of the wav file at 800 equally spaced data points. Note that N-channel wav files are first independently interpolated before computing the average of the N channels.
