I and Tumulte went through the code yesterday:
In the class SpectrogramImage in
mediagoblin/media_types/audio/audioprocessing.py, in the definition of
"colors" you can modify the definition to fit your needs.
The "colors" variable has to be of the format colors = [(r, g, b, a), (r,
g, b, a), ...]
Where the first rgba tuple is the color of the lower intensities and the
last tuple is the color of the higher intensities. It can be any number of
rgba tuples and they will be distributed evenly over the spectrum.
This is a hack that works today, hopefully in the future we will have it
configurable from the main MediaGoblin configuration.
