Somehow I don't have a good feeling with that aproach of volume
triggered splitting. You have specified another threshold that
virtually does the same as the stop threshold: detect the begin of
silence. Do we really need to detect different levels of silence for
splitting and stopping?

As for the "split after at least n seconds" parameter - it sholdn't be
necessary. I consider it as a attempt to fix something that should be
fixed by setting the other trigger parameters properly. Somehow it is
the specification of a minimal song lenth. But the problem that this
parameter is supposed to fix is something else: avoid to detect
silence by error. That can occur after the minimal song length too. So
this parameter doesn't really fix the problem.

I like that parameter "Activate split when silence for at least n
seconds" though. I just don't know how to find an appropriate name to
fit it onto the screen. Maybe something like "Min Gaptime" which can
be set to off, too.
