This is pretty cool: Audiowaveform, a command-line utility for rendering waveform images from audio files, from the BBC.

Compiled nicely on FreeBSD with no source changes.

github.com/bbc/audiowaveform

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.
