Trouble opening .AIFC files

I recorded an audio file using QuickTime Player. It all went OK until the program closed unexpectedly by itself. The file is on .aifc format, and seems to occupy about 500 MB on my HD (which makes sense considering the lenght of the recording), but when I try to open it iTunes opens but I get no sound.

Do you think it could be possible to recover it (or at least a part)?

I'm sorry about my poor english. It's an important problem for me, as that recording was made in a conference for my boss.

Thanks, guys!

QuickTime Player-OTHER, Mac OS X (10.7)

Hi Korean_912. I have a similar problem right now, the difference is that I can't open the file. I don't know what is happening, but when I try to open the file with iTunes or VLC, nothing happening.

In my case, the audio file have 4,29 gb but the duration time is 00:00.. Very strange!

Did you find a solution for this problem?

You need edit your AIFC file in Hex mode (i am use iHex)

1 open your file in iHex

2 you need end adress file. for this scroll you file down. one click on left part of iHex window with addresses of bloks (to change the numerical address in 16-bit system)

3 remember end adress (like: 00F3 DC00 or FFFE 1420)

4 + 8 for end adress (00F3 DC08 or FFFE 1428)

5 now in file go to 0000 0FF4, and write in this adress, number of p4

6 save file in iHex

7 enjoy!

This worked like a charm!!!! Thanks so much for posting this. We were ~45 minutes in to a podcast when our machine froze!!

Btw, if anyone is looking for the file, I didn't find it in the usual temp directories, I found it here:

/Users/Don/Library/Containers/com.apple.QuickTimePlayerX/Data/Library/Autosave Information/Unsaved QuickTime Player Document.qtpxcomposition/Auto Recording.aifc

(as described here https://www.macstories.net/news/recovering-a-lost-quicktime-recording/)

You saved our butts, ty!!
