Tried that, showwaves has a way of setting the FPS, so with that the whole
segment is defeated.
That would not be bad, but sadly, the resolution is so low that with large
segments (I need app. 23 seconds), the image stays blank...
(and fps and resolution are not to be combined according to the docs..)
