I had a more detailed look at this and found a way to do exactly that,
thanks for the hint. It's kind of an obvious approach if you think about
it but sometimes one is just blind ;)

I guess that makes this code/patch irrelevant for now.

One question left is, if there is any interest in having a script to to
the waveform generation in the tools section. Otherwise I would just
add my findings to the ffmpeg wiki.
