Yeah, sometimes I'll go through the audio and silence those bits but sometimes it's more hassle than it's worth, I say that because I think it annoys me more than anyone else who watches my vids xDIt's more just that a noise gate doesn't descriminate types of audio. You set a threshold and everything below that threshold is zeroed out. So, looking at your waveform, there are parts before and after speaking that would meet the criteria.
Honestly, what you're trying to avoid is part of the job of a good editor.Going through and dealing with the minute nonsense in a recording.
