I use audacity to edit multi-track audio for a podcast. All silences are cut out so that clips can be moved around, to compensate for the online latency during the recording. Here are two screenshots displaying what I mean.
When I want to clean up the recordings with a high pass filter (HPF), Audacity adds silence to all these empty parts.
The silences are a hindrance because they get in the way when I want to tweak clip timings.
Is there a way I can either:
Run the HPF on multiple audio tracks at once without it adding silence clips to the track,
or
Run the HPF on multiple audio tracks at once, and remove all silence clips in a batch operation?
Today morning, I had the idea to test the HPF (>10 KHz) by using the “Equalization”. I was working with a 32-bit wav mono track of a few minutes long.
I exported the new mono track; also as 32-bit wav type.
I closed/run Audacity and reloaded the latter.
I noticed that its track is shorted about 0.5 sec.
I thought I did something wrong. But after reading here, this result might be a natural side effect.
But if this shouldn’t happen and the new filtered track should be, after being exported and reloaded (32-bit wav), of the same size as it was (as of the original unfiltered track), I will surely repeat what I did to find out what I missed.
Ugh, RTFM! When I saw this option in the menu I figured it’d only split clips, not clear the silences. This feature is going to save me a lot of time in the future.
