[logan_carroll]

Having the same problem described in these threads, none of the suggested fixes have helped.

I updated to Audacity 3 last month for editing a podcast. It worked fine, at first. I edited a full episode with no problems. I edited about half of my current episode, and suddenly the program has effectively stopped working. Any action I take in the program takes at least 30-seconds; including clicking on the "file" menu to open projects. Copy and pasting a .1 second clip took nearly two minutes.

The problem is limited to Audacity. Nothing else on my computer is running slow, even when Audacity is open. Audacity, meanwhile, is always slow, even if no other program is running. It is slow even if no project is open. I have tried restarting my computer multiple times, I have tried reinstalling Audacity, and saving the project under a different name.

I checked my task manager, and my mem/cpu usage are well below my computer's limit. Audacity, if this matters, is taking about 30% of my CPU as soon as it opens, even before opening a project.

At this point, I'll probably switch to Reaper, but I want to recover the hours I've got in this current project, if anyone can recommend how to do that.

The mystery deepens: I spent half an hour muting tracks to export chunks of the finished audio... The export function works like normal. Only part of the program not running slow.

Try updating to Audacity 3.0.2.
I think that's unlikely to be the problem, but 3.0.2 does fix a number of issues.

I already tried: nada! But thanks for taking the time to reply.

When I try to delete or silence sections of audio Audacity hangs up for 20 seconds or so. In the past the change was instantaneous. Strangely it just started today. Yesterday there was no problem.

What size is the project "AUP3" file when Audacity is closed?

About the project:

• How many tracks?
• Mono or stereo tracks?
• How long are the tracks?
• What is/are the sample rate of the tracks? (look in the panel on the left end of the track)

What is the full path + file name of the project? (For example: "C:\Users\Tim O'Brian\Desktop\Greatest Song in the World.aup3")

It might have something to do with clip boundaries? I have a 1 hour file with hundreds of clip boundaries, and it's excruciatingly slow to do any edits. It seemed like it was slower the further along I was in the file which finally made me suspect something. I tried using Edit -> Clip Boundaries -> Join on the entire track, and it locked up the UI for more than an hour at 100% CPU before I killed it.

I exported as a WAV, brought it into a new project, and was able to edit with no problems.
