How to fine tune the pitch of audio tracks

[hardgristle]

I'm working with some audio that is not quite at concert pitch and I need to alter the pitch slightly
to fit the A440 of my virtual instruments.

I can see that in ABleton I am able to pitch shift an audio track by semi-tones but how do I fine tune it?
These audio files are about half of a semi-tone out.

Any advice would be welcome, thanks.

right underneath the pitch button is a ct's control -50/+50. see where it says 0 ct?

Silly me. I always thought that control said Oct - meaning it would pitch the audio up or down in octaves.

Thanks a lot Anthony.

Cheers
