Solved it (For me at least)

Assuming you’re doing as I was, i.e. recording audio in Garageband, bringing it into AdobePro for editing.

My problem was thus ;

my AP project had audio settings of 48000Hz
(found in sequence settings/audio)

However, GB was recording and therefore exporting in 44100Hz

Obviously, AP was therefore playing it back at a slower speed, hence lower pitch.

So it wasn’t technically a pitch issue, just a Hz speed issue… Changing this setting returned my audio to normal playback 🙂
