Someone else had problems with this…

sqlite database problems?


Which Audacity version? 3.0.0 or 3.0.2? (look in “Audacity menu > About Audacity”).

If it’s 3.0.0, please try updating to 3.0.2 (available here:

I’ve upgraded to the latest Audacity. Still no luck unfortunately.

Is the problem with one specific project only? What exactly is happening?

Yes the problem is with one specific project only

From my perspective, since it is only this specific project, I would salvage what I could and then toss the project.

Is it possible to save any of the project to a WAV file?

Is it possible to copy and paste any of the project to a separate Audacity window?

Do you recall which files you deleted?

A possible explanation for why the problem occurred:

While an Audacity project is open Audacity uses a temporary file (with a “.WAL” file extension) in addition to the project “.AUP3” file. If you accidentally deleted that .WAL file, then that would corrupt the AUP3 project file. Audacity automatically deletes the WAL file when the project is closed - it must not be deleted manually while the project is open.
