That is correct. It would make sense for review purposes to have scene
cuts marked with this method rather than with an optical mark, which
could divert from more important visual aspects of a movie.
Working with lots of temporal files wouldn't be too bad.

Right now I have to get familiar with sox in general. So thank you all
for your kind help and example command lines.

sox input.wav output.wav [effect[effect-options]] for doing effects
stuff is clear so far. Concatenating and mixing is easy to figure out too.

I read about channels and rate (-c 2 -r 48000) but I do not know how to
create a wav file of a given length with empty channels. I'm afraid that
is simpler than with logic to solve ;-|

Thank you very much.

Best Regards,
Rainer
