Hey,
I've got a project that I originally recorded on a mac. During that recording, Audacity crashed (yes... I know... mac's don't crash). Anyway... I've recovered the file, but I cannot get it to play back on either Mac or PC. I can still see the wavform though so the audio is there. What's a guy got to do here?
No Audio Playback on a recovered project

Audacity 1.2.x is now obsolete. Please use the current Audacity 2.1.x version.
The final version of Audacity for Windows 98/ME is the legacy 2.0.0 version.

Re: No Audio Playback on a recovered project
<<<I've got a project that I originally recorded on a mac.>>>
Probably not. Most people who say that without qualifying it have the AUP file and not much else. The AUP file's job is to point to the thousands of other files that make up the show.
<<<During that recording, Audacity crashed (yes... I know... mac's don't crash). >>>
You can get a Mac to crash by running the hard drive out of space. If you do it with Audacity, then whatever show you were working on when the machine took a dive is probably history.
<<<I can still see the wavform though so the audio is there.>>>
The blue waves are drawn by the first two AU files in the _data folder. Those are picture files. They represented the characteristics of the show at one time. It's perfectly possible to damage a show so bad that there's blue waves and no sound at all.
You can open up the AUP file in a text editor and read it. It's words, it's not a sound file. Here's one...

Note there are directories and folders listed inside the code. This is one reason Audacity Projects don't move well -- or at all. If no other good reason, directories are forward slashes on the Mac and back slashes on the PC. The AUP file is never going to find all the parts of the show to open and play it, particularly if it was damaged before it left the Mac.
<<<What's a guy got to do here?>>>
People have edited the AUP file to point to the right directories. It can be done. But your directories have to actually be there and in good shape. Pointing to directories with damaged sound files isn't going to do much good.
Note in the example the top code is "Left" and the bottom code is "Right." Everything must match. In the example, I added spaces and blank lines to make the code easier to see. Your AUP file may not be so neat and orderly.
You could also plan the reshoot.

Re: No Audio Playback on a recovered project
1) Yes, I know that. I was referring to thee .aup file and those audio files.
2) The HD had enough space. There was at least 10 GB left over. This wasn't the problem. Nice guess though. The recording itself exceeded 5 hours however, but there was enough disc space for that. It honestly was a large project.
3) To give a bit more detail on this... I had audio in the recovered project until I merged it with more recovered audio. Translation, I had to split the data files into 2 sets to recover them. I then tried to merge them into one project. I had audio until I did that. So, while it's nice to know that there are separate images
4) I did all the reconstruction on the Mac. I have since moved it to the PC for one final try before posting here.
5) As far as planning the reshoot... yeah... it was a live event involving performers from Atlanta, Ga, Birmingham, AL and Vancouver, Canada. There is no reshoot.
Anybody else have any ideas of how to do this?
I think my next steps are to try a new recovery on my PC.

Can we guess that's way less than 10% of the drive? Audacity does everything internally at 32 bit, so say 700MB per hour for six hours works out to 4.2GB. The first time you try to do any production or show management, the UNDO files will kill you.
Why didn't you stay on the Mac? There you had a chance to recover this...
If you were running 1.2.5 on a Mac/Intel/Leopard, that may be a good place to start looking for problems. That's a known unstable combination.

Re: No Audio Playback on a recovered project
It was an 80 gb drive so... no. Plus, that was AFTER the crash and after I exported several other nights of shows. Honestly, I'm not worried about WHY it crashed. I have a gift in crashing Macs. Let's just move one. It's also on a G4 not an Intel with the stable version of audacity and the files are all still there.
Why are you focused on the Mac issues. I've moved on.
