Recorded at 2x speed. How to slow down and reestablish correct pitch


I have a recording that recorded at double speed and now I have a recording that sounds like Alvin the Chipmunk. How do I slow down the recording and reestablish the correct pitch? Any help is appreciated

Change Speed effect:

Effect > Change Speed. If they’re both wrong, that’s the tool. It gracefully changes the playback speed until you get what you want without too much sound damage.

Did you do this intentionally? By accident? Are you helping out somebody?
