I apologize for not being clear enough.
What I mean is: How can I AUTOMATICALLY trim the segments that have no sound?
I spent a lot of time trimming them manually.
In order to shorten some videos, I would like to get rid of the parts that have no sound, my videos are mostly tutorials in which I explain technical topics, so there is almost nothing I want to keep when I am silent.
How can I trim only the segments that have no sound at all ?
