Recording crashed at stop

While recording a podcast on Audacity 2.4.2 on a Windows 10 laptop the recording didn’t save at the end. When clicking stop, Audacity crashed, when reopened I had an error about Orphan Blocks, which appear to be the totality of my recording. Is there a way to recover this recording? It was a fairly difficult multi-lingual podcast and I know it’s going to be hard to get people rescheduled to re-record. Here is the log, minus the extra 1400+ Orphan block file items

In a word, no. :frowning: Note that the major focus of Audacity 3.0.0 was to restructure the way Audacity stores its data in the hopes of avoiding catastrophes such as this.

You can download Audacity 3.0.0 here: Audacity ® | Downloads :smiley:

It was a fairly difficult multi-lingual podcast

And multi-location? It’s not the worst idea to get the conference app (Skype, Zoom) to record the whole show as a backup.

Audacity 2.4.2 is usually pretty good about simple recording a show. That was the standard version for quite a while. The little AU files are about 6 seconds each. Can you open them and play six seconds?

Open the AUP file in a text editor (don’t save anything) and read it. It should look something like this with collections of English and English-like words.

It’s possible that the actual sound files are not damaged, but Audacity just can’t figure out how to open them. How long was the show—or would the show have been.

I don’t mean to get your hopes up, it’s still going to be almost impossible to bring it back, but it would be good to know what happened.

A note. Is this the raw recording? If there are any edits in the show, then that’s the end of the world.

Yeah, the audio files are in tact, playable, and importable to audacity. The aup file doesn’t reference any of them. My only thought for I worked differently is I saved the project prior to recording. Other times I’ve recorded before creating a save file and editing.

No edits were made, it was just over an hour of recording and we’re already rescheduled for Tuesday. I tried a lot of different ideas I found but ultimately don’t believe I have the time to fix it. I will definitely download 3.0 before my next recording!

Thanks for the help!

Smirkster, as you have done no edits - this Wiki page may help you

Peter.

Are you devising a backup recording?

This is an important broadcast recording I did. The stuff on the left is my setup and Audacity. The stuff on the right is the client’s backup recorder.

Koz

Whatever you do as a rescue is going to take time. You get to rearrange/compose an hour show in 6 second chunks.

You are also warned against trusting an important recording to New and Improved techniques, software, or hardware.

That’s the equipment list for a field sound shoot. No, you can’t read the knobs on the mixer any more. I know where everything is and how it works.

It’s a Shure FP33. This is what it looks like out of the box.
