The python code to show wave data from a command line file name is above.
You can modify it easily to output a .png image. Read matplotlib
documentation.

It's fairly trivial to write one your own with python using scipy. Should
be in the ballpark of 20 lines or so.

Hi *,
Is there a command-line tool akin to `sndfile-spectrogram` that
generates an image (preferably PNG) of an audio wave-form?
I found endless GUI apps, but command-line tools are scarce.
TIA
robin
