Can logic fix a corrupted audio file?

Hello,

 

I recorded a band rehearsal with a Roland Edirol R-09HR portable recorder. The first track won't play past the first 4 seconds, even though it is 3:29 in duration. Tried Logic and other programs- no luck. All other tracks were fine, and I didn't change any settings during the recording process.

 

Is there any way in Logic to fix this file?

 

File info:

 

MP3 audio

8.4 MB

Duration 03:29

Bit rate 320,000

 

Thanks!

Try playing via VLC and see if it works via that...

VLC can and does often... play corrupted files.. If you can get it to playback through VLC then you could pipe the sound from VLC and re-record the output to another program such as Logic.. via SoundFlower for example..

 

Also, if you haven't tried it yet, Audacity might work too..

Failing VLC or Audacity.. if you ever can get the MP3 to playback.. you can use SoundFlower in the same way with whatever playback program works..

Logic cannot repair a damaged audio file.

 

Try Backline Basic from Audiofile Engineering - this is an excellent audio file repair tool. The demo version is fully functional.

Thank you both!

 

I tried Audacity, VLC, and Backline Basic. No luck playing the full file. VLC recognized the correct duration, but couldn't play more than the first 4 seconds. Backline Basic said the file appears to be OK, so I couldn't do any repairs.

 

Looks like i'm out of luck on this one...

MP3 is more a streaming format than a file format, you can cut out any chunk of data out of the file with reasonable size and it will play back in any MP3 player. Modern applications (iTunes, etc) add a prefix or a suffix data chunk, but that is optional. The file size seems large enough for 320kbps, so if the recorder didn't record complete garbage, you should be able to recover the file easily (I expect the header/suffix be defect). I would fix it with any hex edit, but if you can't read the binary data of a MP3, you will have a hard time.
