How do I adjust sound pitch?

I am making a game and I want to randomly adjust the pitch of the gun fire sound effect every time it plays. But I cannot find a way to easily do that. Does anybody know a way to easily adjust the pitch of sound effects in construct 2? If anybody can help please respond, Thank you.

PS I am not apposed to using 3rd party plugins.

You can do this with 'Set Playback Rate', an action using the Audio object. I'm not sure how accurate it is though. You could also adjust the pitch with third-party software for a number of sounds and then in C2 'choose' a random sound each time the gun is fired, or play them in sequence.

Thanks
