Cool, I like the idea and I actually use this feature a lot in Google Podcasts.

However, I believe there is a way to do this with a single ffmpeg command. I remember watching lecture videos with higher speeds wondering about the huge amount of silence that made it still pretty annoying. I didn’t find anything simple to trim silence on audio and video combined and finally only listened to the audio with trimmed silence using ffmpeg.

Edit: It's literally just an audio filter in ffmpeg, see https://stackoverflow.com/a/29411973
