I was recording a skype conversation via soundflower.
After like 20 minutes, we made an interruption, and I created a new track for the second part.
In the end, I realised I hade overwritten the first track, so I saved the project as existing as a .aup file, then used the cmdZ function to recover the first track. AT the time, I was thinking to merge the project I saved with the previous version.
Problem was, when I wanted to open the .aup project I saved, it was nowhere to find, not even in the private->var file where temporary files are usualy saved. That’s why I used the recovery program and found a .au 1.36G file matching the time I saved the project.
My actual problem is that the program doesn t recognise this .au file. It tells me to open it as “Raw”. When I do it, it’s completely saturated. There are a lot of options when I open it, but I don t understand all of them, so I used the default and tried a few more, but not all combinations (would be a lot).
Saving a project does not create a single large file - it creates a small “AUP” file, and a “_data” folder containing many small data files (see: http://manual.audacityteam.org/o/man/audacity_projects.html#AUP)
Unless you “Exported” a file from the project, then there will not have been a single large file created.
A 20 minute mono recording at the default sample rate and bit format would be around 200 MB.
A 20 minute stereo recording at the default sample rate and bit format would be around 400 MB.
Audacity does not create large data files unless you export, and you have not said that you exported a file.
Audacity is able to recognise and import .au audio files using the normal: “File > Import > Audio” command.
Consequently, I don’t see how that “1.36G.au” file has anything to do with your lost track, and unfortunately I can see no way of recovering your lost track.
