I recognize I’m commenting on this old comment to an old post …
I’m going to politely bump this, as I came here to request a feature to either automatically detect (or, with respect to the answer about not wanting to do it automatically at [Feature Request] Skip silence between "Hidden" tracks perhaps a way to manually mark segments in a track to skip) because I have a number of tracks with extensive silence. Having Plex detect sections of tracks with silence during processing, and then offering an option to skip these, per track or globally, would be nice.
IIRC, there’s a feature in iTunes where one can set parts of tracks, beginning and ending, so I used to do that. For tracks with silence in the middle, I would duplicate the track and set the end and start point of each copy appropriately.
So, in summary, that’s all … bump!
