I know it's also possible to generate a waveform image using sox & gnuplot, but this utility is much more convenient.
Might be a fun way to add amplitude information to my show's spectrograms. Maybe apply amplitude to hue/saturation or something.
Probably more work than it's worth, but neat to think about.
