FFmpeg / blank audio

Audacity Help Forum Windows
1

I’m using version 2.2.2.

I was editing audio and the laptop battery died. When I try to go back in to the project, I get the Automatic Crash Recovery window with the project, I select it, get the old Audacity did not recognize the file type and suggesting to try installing FFmpeg and importing raw data.

I am able to import it without FFmpeg, but I installed FFmpeg anyway. In the end with or without FFmpeg, I am experiencing the same problem: the audio comes up blank and like a fraction of a second long.

I had the audio saved in the standard two channel stereo, but also done to 32-bit float and 96000 Hz which is not typical. I change the encoding and sample rate to match what the audio was and I get the blank audio.

What do I do now to recover this autosave file?

I was into like tow hours of meticulous audio editing and it would be a nightmare scenario to have to do this all over again.

That version is obsolete.
The current version is 3.1.3.
If you need to run Audacity 2.x rather than 3.x, update to Audacity 2.4.2 (available from https://www.fosshub.com/Audacity-old.html), or for the latest version: https://www.audacityteam.org/download/


FFmpeg and import raw data will not help for corrupt projects (they “may” help for unrecognised audio files, but not for projects).


Unfortunately I don’t think you have any choice. If auto-recovery fails, then it’s unlikely that there is enough of the project to be able to recover useful amounts of the project.

Tip: When doing a lot of editing on a laptop, ensure that the laptop is plugged in. If the computer dies, then it is unlikely that an open project will survive.
