faulty audio

[Raywoodbrigade]

I recorded a meeting on my laptop on Tuesday last (24th).

The audio runs at about 20% speed. It's like taking 2-3 seconds to say one word.

I have tried to fix it but no joy.

I and using the up-to-date Zoom program

The meeting lasted approximately 45 minutes but the recording is set to run for 3+ hours.

Any help would be appreciated
