I have noticed a rather annoying volume variation in my voiceover speech, it is a little like ducking, though I have turned off the ducking option in the VO menu.
I first noticed it on a macbook pro, I returned it after realising a retina screen was kinda pointless for me... Yes, stupid, and got a macbook air instead, the problem was still there so I am assuming it is a software problem. Has anyone else had any experience of this? I have checked the site but either I didn't enter the right search terms or it hasn't been covered.
I do also have a problem where when hitting certain groups of words voiceover fragments, it sounds like some sort of latency problem, simply turning VO off and back on again seems to solve it.
