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.
