Thanks a million testerics, you AWESOME!!!

Is there any chance you could recover more of the file?

The Original file was 2.35 MB 38 min and 17 sec, the Recovered is 1.48 MB 25 Min 51 sec.

So there's 12 Min 26 Sec still missing.

Is there anyway you can work your magic and recover this missing audio?

Thanks for everything so far you awesome!!!!

[testerics]

The recovering process was complete (100% from what you upload). Even if the header of your recording is showing you 38min&17sec, the file was broken after 25min&51sec.
So, nothing to recover after the file was ended prematurely..

[VideoGuyErwin]

Thank you sir, you are awesome!!!

Hi guys! Sorry for the disturb, I'm an Italian student, yesterday morning I recorded an important lecture at the university with my smartphone and I got a .3gpp audio that seems corrupted. Anyway the lenght and the filesize are detected correctly, I also have a .3gpp.tmp file
Is it possible to recover this file?

Many thanks in advance

[testerics]

@Mich-C, your recovered file is attached. But is 45 minutes of silence, only some noise at the start and the end of the record.
I think it was a problem with your smartphone at that moment, not with the file..

Dear testerics,

You are amazing! I am a Taiwanese.
Yesterday I went to my class and took audio recording.
But my cell phone was running out of power and shut-down.
So I got a corrupted (unreadable, bad) *.3gpp file:
https://drive.google.com/open?id=1N2c-P_ArIgUa5IcUIae52jUldOiO_wct
Here's a good one (recorded using the same device) which is longer than the bad one:
https://drive.google.com/file/d/1FLDfEwpD2CfGTgN49sOawgPC1sZKxXIe/view?usp=sharing

ps. I have tried to use HxD Hex Editor to copy the all contents after "mdat" (of the bad one)
and paste-write (not insert) them to the good one, but this doesn't work.

Could you please help me to check this file? Thank you!

Best,

Hi testerics, what a magical thing you've done!
Thank you very, very much!
I'm very interested in what method you used.
If possible, would you please just share some tip?
(I have worked with this file by Hex editor for hours...but some of you guys have spent years!)
Anyway, thank you very much for your kind help again!
Happy Valentine's Day!

Best,

i was in a car crash a few days ago, and the car camera didin´t complete the video from the crash.
Can anyone give me a hand

Thnks
