I’m using Audacity 3.0.2 on Windows 10 (with full updates)
I recorded 12 minutes at 44100 mono, duplicated into a second track which I made trackwide changes to.
After saving and exiting, the result is a 1.4 GB aup3 file. This seems extraordinarily large to me.
I am using the same settings I had with 2.x and into 3.0.0. I used 3.0.0 to convert many projects into the aup3 format and they are all the expected file sizes.
Attached is the debug report.
If it helps, I can upload the file to a file sharing host and DM a dev a link to look at it; its content my own work. Audacity_dbgrpt-4256-20210516T035454.zip (19.5 KB)
12 mins = 720 seconds.
720 s x 44100 samples per second x 4 bytes per sample x 2 tracks is about 0.25 GB.
Looking at the “project.txt” file from the ZIP attachment that you posted:
If I added up all of the sample counts from the blocks correctly, there are 63192341 samples, which again is about 0.25 GB.
It’s normal for projects to get bigger as you work due to the “Undo” history being retained, but that should go away when you save and exit.
Using the basic right-click > send to zipped folder
size 721 MB (756,915,411 bytes)
size on disk 721 MB (756,916,224 bytes)
This aup3 is the one I did the earlier operation on: tracks duplicate / reverse / duplicate tracks delete. I don’t have the original-original one (disk space issues)
It is still larger than expected, since the actual project should contain about 250 MB of audio data, but that’s a lot smaller than would be expected from 1.35 GB of audio data.
I have an ongoing email discussion with one of the developers about this. I’m currently waiting for a reply about what we do next.
Are you able to upload that 7zip file somewhere so that we can examine it? There are a few “free” (advert supported) file sharing services available, or possibly dropbox, Google drive, One drive, or similar.

7zip is pretty magical.

This isn’t time-sensitive since I was able to work with the backup aup3 we generated earlier. In the next day or so I intend to make another project in much the same way; perhaps this can be reproduced.
I’ve downloaded the file, but if you could keep it up for a while that would be useful so that I can pass it on to the developers.
Interestingly, if I extract and open the project (Audacity 3.0.2 Linux), reverse the first track, Undo, Save, Exit, then the project shrinks down to 186.3 MiB (195,362,816 bytes).

That is interesting. I double-checked:
Reverse the first track
Undo
Save
Exit
I see no change, although the modification time updates.
