This is what I've been bitching about with GT and Forza for years. Authentic audio? Who gives a rats, make the audio sound exciting like there's a thousand wild cats under the bonnet screaming to get out.
Try the GT5 class and pick the Ford Capri. Oh my gawd, the sound is to die for as your motor screams at redline.
I posted my impressions of the audio and also some suggestions over at the Project Cars forum.
To have the option of exterior samples in the cockpit or a slider or two for engine/exhaust mix because those exterior sounds are absolutely mind blowing!
Also asked for adjustments to AI/player vehicle volume because at the moment I simply find it extremely hard to hear my car even when other cars are pretty far away from me.
Stephen Baysted, the Audio Director at SMS 'liked' my post which could be indication that those suggestions are hopefully implemented in the future..
