Detect and delete silence
When working with separate tracks of several remote guests on a podcast or talk show it is essential to delete "silent" parts of the track when someone isn't talking. Sometimes these parts are not silent at all (because of a lot of background noise or leaking audio from headphones), but that makes it even more important to have them removed.
I would like Hindi to be able to identify and insert breakpoints around these sections automatically and remove them upon request. That would make my life soooo much easier.
We have been looking at how we can implement “delete silence” in Hindenburg. I think we should be able to come up with a solution for that in the near future.
We have been working on some other features that touch the same area, with out latest Beta feature called “Magic Levels”.
It’s a non destructive way of applying Side Chain Gate – so that mixing multiple recordings become very easy.
No the same, I know – be it might help out in the situations where you are looking to reduce Bleed or Noisefloor.
This really takes a lot of time. I never thought about automating this. Great idea!
Since it has already been done by others, it can't be impossible.

Here's a nice write-up of this type of workflow and how Strip Silence helps, by Jason Snell of Macworld. https://sixcolors.com/post/2015/02/how-i-podcast-editing/

This would be extremely useful and I hope it's added soon. Logic and Pro Tools both have this and call it the "Strip Silence" feature. You can set some basic parameters and they take a long audio region and remove the silent or very quiet parts, leaving many smaller regions with gaps between them. This makes editing a lot easier, because with one click you can select and delete unwanted regions.

I would extend this with one of the biggest features from Audacity not yet replicated anywhere else: Truncate Silence.
The requested update is similar to Logic Pro's Strip Silence, which can set a level and outright remove all audio falling below that threshold. Audacity's "truncate silence" goes one step further by doing two things:
- Selects only silence that spans all active tracks (so it won't strip when a person is listening to another, in a different track, talking).
- For all "silence" below the the threshold it not only cuts across all tracks, but also tightens the audio removing the gap altogether.
The effect this has on spoken podcasts is immediate and spectacular.
