Can't open .aup project

Windows 10. Audacity 2.1.2. I saved the project, but I get an error message telling me it doesn’t recognize file and to try importing raw data. The .aup project is in the same location as the .data files. In the directories, I am missing the audacity_1_2_temp folder – I have just the audacity_temp folder and it is empty. I have no .bak or autosave files. I have tried numerous things to recover the project. I don’t know what encoding and byte order’s I need to import raw data. When importing audio from the .au files, I know that there is a long, tedious way to sync the tracks, but there are so many, and the project is edited. Is there any way to recover the project?

If you open the AUP file in a text editor (don’t save anything), is it blank?

It normally looks something like this.


You mean the .aup file and not the .au file right? I opened the .aup file in notepad and it is blank

Most (but not all) of the AU files are sound snippets. The job of the AUP file is to tell Audacity how to reassemble all the parts into your show. Without the AUP file, the job is much more interesting.

I think these are the current instructions for Disaster Recovery. The files are not in simple numerical order.


I believe this only works if you’re trying to save a fresh recording. If you’re in the middle of an edit session, the show may be gone.


Okay. Thanks. Like I said before, in the directories, there is only the audacity_temp folder, not the audacity_1_2_temp folder. Is there anyway to get the latter with a .bak file?

I personally don’t know. All I got is what’s in that manual entry. Maybe a senior forum elf will come by.


If the AUP file is empty and if as you say, you were editing, I’m afraid the project is not recoverable by any automated means. All you can do is literally drag in the AU files from the _data folder for the project. There are not intended to be any AU files in the temp folder after you first save the project.

This problem usually happens if you shut down the computer or close the laptop lid before the project has finished saving (the AUP file is saved last). If you don’t touch your mouse after using the save command, Audacity should tell you in the Status Bar at the bottom when the project was saved OK. Then it should be safe to shut down.


Thanks all! So, I decided that there was too much work to try to save. However, after tediously renaming and searching, I found the drum tracks. I want to at least recover those. The most difficult thing is that each track has a replica stereo track. Is there an easy way to sync up the tracks to be in stereo? It doesn’t look like audacity has a “move” track option, just cut and paste…because a “move” track function would make this so much easier.

The AU files for left and right channel will have the correct length but may be transposed so that right is above left. If each AU file is in its own track you can move the track up and down by dragging on the Track Control Panel to left of the blue waves, or use the Audio Track Dropdown Menu.

For moving clips left/right or up/down if there is space to move them you can press F5 to go into Time Shift Tool.


Okay, so I feel dumb now. Thanks for all the help – I know how to move the tracks now. So, now, my next issue: I managed to find all of the drum tracks and synced them up for left and right stereo. Now I am merging them together…my problem is, after doing the manual recovery tool (zero crossings, trim, cut, END, paste, etc.) it successfully merged, BUT, there is a click noise at the crossing…how may I eliminate the click noise?

Matching the direction and duration of the blue waves isn’t the only way to solve clicks and pops. There’s also DC Offset. This illustration is exaggerated, but it doesn’t take a lot of offset like that to create a noise.

If you zoom in and magnify the blue waves, can you see any damage at the click point?

The other problem could be trying to patch a stereo recording. It’s not unusual to not be able to correct Left and Right at the same time. Then you have to start using the video tricks of rapid, brief dissolves or fades instead of cutting.


Yes!! The offset was an issue!! Thanks! While waiting for a reply, I researched and realized that fading in and out of very small portions, milliseconds, of each track (at the meeting point) helped tremendously. There are still a few glitches, but it’s just for a promo demo so it’s good enough. Just glad I saved it, because doing the drums over was not an option. Thanks for everyone’s help, much appreciated!! :slight_smile:
