HELP: Audio File Recovery

Did you have autosave on? If you didn't select that option, that's your fault not Cakewalk's fault. You could have set it up to save every 10 minutes or so. Also, you could have hit CTRL-S anytime during the recording (preferably between songs) which would have saved up to that point.

Search your audio folder to see if there are any autosave files or any Cxxxxxxxxx.wav files there from the time of the recording.

Otherwise...... LESSON LEARNED!

Lesson Learned for sure.... I don't mean to blame Cakewalk, I love the program feel its the best one out there. I dod not configure it specificaaly to auto save, my fault.. I though it defaulted (my fault.....).

I know its a BONEHEADED problem, should have a working battery at the least, hibernating would have been recoverable.

I was on stage, so I could not hit control-s.....

AUtosave is the correct way to fix the issue, and would have saved me..

Specifically I am wondering of there is a way to recover the files. (Not a sonar problem, an operator problem....).

try one of these

use it to search your hard drive for .wav, .cwp, etc

I'd be willing to take a look at those corrupt files and see if I can salvage them for you. Let me know.

Yeah, I'd give Adobe Audition a try. Or SoundForge, or maybe Audacity (it's free I believe).

Or better yet, take bitflipper up on his offer. If anybody could recover them, I'm sure he could.

Hi,
 
New here.
 
Something very similar just happened to my Sonar 7 system, but instead of power off, Sonar crashed when I hit space bar to stop recording. 
 
Computer is :
3.01GHz pentium 4 with 1.00GB RAM
RME Hammerfall HDSP-9652 Sound card
Sonar 7
Has been running stable for a while now. 
 
2 1/2 hours,
26 tracks,
48KHz, 24 bit
Live recording of open air Carols show
ADAT direct outs from PA mixer - a Yamaha M7CL-48 with PA mixer running word clock master and the computer slaved to the console
I sat my PC monitor behind the console's touch monitor so I could observe sonar's record levels without moving my head and nothing went over -9dB all night

I did have to increase the latency on the sound card driver to get it to record all the tracks without dropping out
 
Each file is 1.3GB and a bit, so it lt all appears to be there.
 
I tried to find my way around audition, but not happening..  maybe still too gig tired.  When importing raw data, in little endian, I get very distorted high level signals, When importing BIG endian, I get distorted low level signals.. or maybe vice versa ... either way, niether is clean and usable.  Audition always says the imported file is 32 bit float, but my files were recorded at 48Khz, 24 bit PCM(?) so I am guessing it is a bit depth problem.  only downloaded audition this morning and the manual doesn't appear to say how to change the current project's bit depth. 
 
Any hints?

Linz, a few points.

First, this thread is 5 years old, you'll get a much better response by posting a new topic

Second, now don't take this the wrong way, but your pc is MASSIVELY underpowered for this sort of activity. 1Gb of RAM simply isn't enough.

Thirdly - depending on your Operating System, you might have reached the 2Gb limit on file size which any 32 bit version of Windows imposes, hence the crash

Download HexEdit and save 2 alternate versions of the WAV file...  remove 1 byte from the top of one and 2 bytes from the top of the other.. then try again...  24 bit audio is saved using 3 bytes... you should attempt to load the RAW data using an offset into the top of the sound file... Sound Forge allows that without having to use HexEdit.

That's going to corrupt the file, I'm afraid. The first 4 bytes are what identifies it as a RIFF WAVE file. Altering that with a hex editor would most likely make most audio software just barf it back out.

He's opening the files as RAW files - so the headers are going to be noise at the top and have to be edited out -- if he's trying to do a raw data recovery it'll work

Some free utilities I've written:

Thanks everyone for your help.

I finally got it solved, but audition wasn't enough on it's own.  I had to re-create as much of the headers as I could by hand first, including calculate the file length twice (in hex) with different offset values for each block it occurs in, then audition was able to read the data section accurately.  After fixing the headers for one file, I simply copied it to the other 24 files as they were all the same format and length.

It took a while with loading the files into hex edit, copy/paste, save as, load into audition, save as 24 bit with dithering, load into sonar.... And don't forget to move the original corrupt file and the hexedit output file to the other hard drive to make sure I didn't run out of space.
