Copying small segments of clips extremely slow

I often have to edit long audio files (two hours of stereo sound is not unusual). My workflow involves often moving very small segments (less than ten seconds) unto a separate track, adjusting the timings of these segments, and mixing it back together at the end. I’ve used audacity to do this for years.

I was on an older version for a long time (can’t remember exactly which), but recently I updated and now, whenever I split off a small segment of audio and try to move it to another track, it takes over a minute to do it. This absolutely kills my workflow to the point that I either have to stick to an old version of Audacity, or find a different program.

I haven’t been able to pin down exactly what version this problem was introduced in (it was there at least in 3.4.2, and it’s still there in 3.7.3), bit I suspect it might be due to the “smart clips”-feature (meaning it might be copying the entire two-hour track every time I try to copy five seconds of it).

There was a forum thread (several in fact) requesting a feature to turn smart clips off, but these were closed after some time.

Is there something I can do (other than downgrade to an old version), to reduce the wait times?

If you paste the audio to another Audacity window you have the option to shed the hidden audio

The copy-paste it back into the first window.

This indeed down to “smart clips”.

When you move a section like this Audacity now moves the whole clip/track but hides the extra bits (so that you can expand the moved section later if reqired (and in your case you do not require that).

Whane you move a section like this wuthin a project there is no option to stop this happening, but if you move the section to a different project then you get the option to move just the required part without the full smart clip.

So a workaround for you is to

  1. open a second empty project
  2. move your section to this new project
  3. make your edits there
  4. move it back to the original project.
