Hi everyone,
I think many people might find my post useful so i decided to write my experience. I have several corrupted m4a files since iphone 4 and 5. All of them were corrupted because they were either interrupted by a phone call while recording or because i shut down the voice recording app without the recording to finalize. so i have been looking over the internet for the past year for a solution. i have tried every single software, freeware and what ever else exists but none of them were able to even open these files. the only solution i could find is a website that could read and fix my audio files but the wanted 90$ for each file. my recordings were not so important so i never did it. So yesterday as i bought a new iphone 6, i backed up everything plus recordings with itunes and restored my new iphone 6 with all my old data. guess what ... to my great surprise i found out that for some reason ios 8 was able to read and play also all the corrupted files that i had luckily never deleted... so then i exported them to my computer and they all played fine... its like the new ios 8 was able to finalize or fix the header or whatever of the corrupted m4a recordings... i never tried this with ios 7 since i only used up to ios 6 ...
try it! and good luck ..
