need help recovering a recorded dj mix

i need help me recover my last dj mix.
i used audacity for the first time, and everything went good 2hours of mix,then, audacity crashed, probably cuz i was out of space on the ssd.
audacity can’t recover the recorded because the file seems to be corrupted.
but the file should be there because the recording took the 10go left on the ssd
(had to record all 14 channels of my firewire mixer to record the master 13-14…weird audacity…?)
anyway, no free space left on my hd so the file must be somewhere.
tried to look in hidden folders of audacity to find the temporary files, which i found, but i didn’t find the big file that could contain the mix.

is there a way to recover???
al the hidden/temporary files are there, there is a hidden folder called audacityUSERNAME containing the recorded material, but can’t figure out…help

i use OS X 10.11.6 and audacity 2.1.0

Running out of disk space is likely to be fatal for the project. (the next version of Audacity, due for release soon, has some additional measures to protect the project data in the event of the disk becoming full).

Audacity does not record as one large file, but as a series of small data blocks (“blockfiles”) which are tied together into a single project by the “Audacity Project” file (.AUP). By default, blockfiles are about 1.1 MB in size, and are written into Audacity’s “temp” folder.
By default, Audacity’s temp folder is called “audacity-”, located below the top level in var/folders/. An example path might look like: /var/folders/c0/8p18hd453p3_433cf9_595b40000gn/T/audacity-joe

On restarting Audacity after a crash, Audacity should attempt to recover the project, but if you are still almost out of disk space this is likely to fail.
Automatic recovery is usually very effective, but I don’t know if it will work in the case of running out of disk space. Automatic recovery is described here:

If auto-recovery fails, there is a section in the manual about crash recovery:

That’s an old version of Audacity. The current version is 2.1.2.
The current version is always available via this page:

Audacity does not yet have built-in channel routing. It just records the number of streams requested in the order that the computer sound system orders them. As the “master” outputs on your firewire mixer are on channels 13-14, it may be worth getting a stereo USB audio device to use for those occasions when you only want to record the master outputs. (I use a Behringer UCA-202 USB, which has surprisingly good sound quality at a very low price).

I expect TR. will have to forget about the Automatic Recovery, copy the temporary data to an external drive and try

Can you remind me what those measures are? I thought that fix had been deferred.


Looks like you’re right. I recall that Paul was working on this a couple of months ago and there being long discussions about it, but it seems that nothing was committed.

thanks a lot guys for your answers, i 'm gonna see what i can do , i have recovered 20go of free space, so that should be enough for the recovering…gonna try…
otherwise, you with hidden folder saved somewhere, you guys can do something with it in the worst case…kind of like a damaged hd you give to a pro to recover the data???
just saw your answers…be back…thanks so much!!!

Just to add. The contents of /var/folders/ is cleaned out by the Mac on rebooting. So don’t reboot the Mac until you have done the recovery, or better still, copy the project folder in var/folders/ to your Documents folder or somewhere else in your user space so that it’s safe.


well it seems its gonna be hard, i can’t recover either by automatic or manual recovering method, didn’t really try the manual, as it is a stereo file…
is there a way for you to recover it if i send you the temp folder var…?
here is a pic of the message i get

You could open Finder, use Go > Go to Folder and type

~/Library/Application Support/audacity/AutoSave

Attach the AUTOSAVE file from that folder. Please see How to attach files to forum posts. It is possible we may be able to correct the syntax error at the end of the file, for example there could be a missing tag at the end.

No way that you can’t try yourself.
