[FFmpeg-user] How to get spectrum data using C api

I'm trying to convert an audio file into a spectrogram to do some
subsequent audio analysis. Is there anything on the C level to help
with this?

The only thing I've found is the showspectrum filter, but this outputs
a picture. However I'd just like to read out the spectrum data, I'm
not interested in the visuals.

How should I approach this?
