Default Lice-cap like program for converting audio to .png using colored waveform based on...

... spectral content, as in Reaper.

For linux, using from command line would be cool. Maybe you know already a program which can do this already? Looked a bit, did not find anything. Thanks in advance.

If Reaper itself could do it with its command line parameters, that would be great as well.

UPDATE: While being at it, SVG export would be nice as well. (not a must)

I think it would be better, if there's an Api-function for the export of spectral-colors of a specific take, stretched to width/height-parameters.
Some flags-parameters would allow the different modes and inclusion of a useful chart-axis.
This is a task best suited for scripts, imho.

One more question to ask for this: Shall this include spectral edits or just the regular spectrals?
What about spectrals pre/post fx and shall it include take/track fx?

What about a spectral from Startposition to Endposition, so we could create spectrals over portions or the entire project?

The last thought could be best suited for the render-process as option to export the spectrals together with the output-stats...

Edit: maybe the thread title should be "way to export spectrals of audio as png"...?

For this task HTML is better like render stats.
