Please help! 2 Separate chapters of audiobook have merged into one after a bug/system crash...

i guess i have to re record?

I think it’s worse than that. Do you know why it happened? Audacity crashed or the Mac crashed?

I think if you don’t find something to fix, it’s going to happen again.

You didn’t say if you were close to an Apple Genius Bar.

Do you keep putting your Mac to sleep, or do you occasionally Shut Down?

If you do shut down and Audacity will not start, you have have to fix the Audacity files.
