Editing is painfully slow

Hey guys,

I had no issues with audacity in the past. But all of a sudden the editing is painfully slow. Almost crashing.

I installed latest version thinking it would help but no luck.

I have a 10 min project I’m editing. When I try to do noise reduction its like it freezes for 2-5 mins I just get the busy mouse icon and it says not responding. But then if I wait long enough the process completes. I get the same when saving my project.

It never happened when I first started editing this project but half way through it became an issue.

I have Intel(R) Core™ i5-2500K CPU @ 3.30GHz 3.29 GHz with 16 gb ram running latest version of audacity.

Which version of Audacity? (Look in “Help menu > About Audacity”)

Latest version 3.0.4

Was having it with 3.0.2 also

Was the project originally created in 3.0.2?
(We know about a bug in 3.0.2 which can cause projects to be painfully slow)

It was. But started happening in 3.0.2 which is why I updated

Select the “Envelope Tool” (see: https://manual.audacityteam.org/man/envelope_tool.html)
Do your audio tracks have lots of random white dots (envelope points) on them?

If so, see this post: https://forum.audacityteam.org/t/how-to-solve-envelope-tool-problem-solved/62655/2

For illustration, here is an extreme example of the “white dot” problem:
