live 9 recorded corrupt aiff files

[wahorn]

I recorded a session with a band we did about 8 takes. I checked them before saving them. Later trying to play them back find out, that all good except in one take I cant load the saved Aiff files because they are corrupt. The files are there I can see the size of them in the finder, but there are no other applications too can open them. All saying they are corrupted.
Anyone knows a tool to fix those Aiff-C files?

try and see if any daw/editor can read them (including freeware) and then re-export from them at same settings.

I have experienced a similar problem as well when recording multiple takes. When I reproduced the issue, I discovered that the disc was "Overloaded" during the recording, causing the corrupt file to be written. I have since remedied the issue by turning off all background processes while recording multi takes.

This happened to me before when recording or saving large recording sessions. This is a common symptom of a "Buffer underrun" disc while recording and/or saving your project. You may have a experienced a disc buffer underrun while recording multiple tracks. This is common when recording more than 4 tracks at the same time on HDD at high res such as 48k/24-bit if the drive or system was not configured correctly. This is more uncommon when recording 1 or 2 tracks at a time.

Basically, a buffer underrun happens when your disc was writing to a portion of the disc that was either fragmented, or you were trying to access or write too many files at the same time is was recording. Files were being "Written" during a buffer underrun may become corrupt because you lost chunks of data, usually in 512,1024,2k or 4k blocks on your HDD.

These files can be "repaired" using a file restoration tool,but results are not guaranteed and you have maybe a 10%-15% success rate of restoring your file to the way it was recorded. I used this before to repair busted or corrupt files before when I transplanted Hard Drives to a new PC, I just forgot the name of the program I used, which was "Forensic Software". You might want to Google and Research "File Restoration Audio" on Google and research some products.

As they say, an ounce of prevention is better than a pound of cure...
Be sure to turn off ALL background processes you do not need while recording. Also, if you have a spare SSD laying around (80-150GB) record your projects to that then save it to HDD afterwards.

Good luck

Well, how is this one for weird behavior. I was recording one track, which was really just a realtime mixdown of two other tracks so everything ITB. During the recording period, I in a fit of stupid un-muted a different track to hear it with the other's as something sounded off and I was sure it was just not being used to hearing them together. There was a massive period of silence and spinning pinwheel but then it started up and the period where I heard nothing had still been recorded and appeared normal. However, when I went to copy the folder, the file the track I had un-muted, which had not been recording, simply enabled to playback, was now corrupted and the OS wouldn't even copy it, nor would Live when doing a collect and save. Strange, no?
