This is what I have come up with so far:
I guess that a combination of
FrameEvaluate and a new
Runtime Function could be the best way to value/volume ect. return values into ex. a Free Frame plugin. Unfortunately I don't know how to code this kind of stuff...
Alternatively another way could be to get
sox to analyse a wav file and export to a .dat file. I have to figure out if it is possible to export a value pr. frame, matching the framerate and then use
ConditionalReader to read the .dat file into a variable which can be used in ex. a the Free Frame plugin.
Any other idears or ways to get sound to manipulate images?
