I’m still searching for a good solution to this issue for my podcast editing needs.
I edit a podcast with 4-7 guests each week, plus a few tracks of transition sounds, chatter, etc.
In editing with Ardour, I cut out the parts I don’t need throughout the recording, then export it as a FLAC file, but that leaves sometimes long silences, so I import that file into Audacity and run the truncate silence effect, use .5 seconds, and all the silence is shortened to .5 seconds and it’s perfect. Then I export to the formats I need, mp3, flac and ogg.
I’ve heard I can use ffmpeg in Ardour when exporting in order to achieve this but the commands I had found previously didn’t work so I kept my edit in Ardour, and truncate silence in Audacity, workflow.
I’d love to figure out how to do it all in Ardour.
It also looks like I could do all 3 file formats at the same time in the export window, but that would only work if I can get a script going that would shorten all the silences to no more than .5 seconds.
I’m also willing to pay someone for an hour of their time if it’s a detailed answer. I have searched and searched, and I’m not the only one requesting this, but I have not found any answers.
I have been trying to use some of these parameters in ffmpeg. FFmpeg Filters Documentation
