As a veteran Gran Turismo fan, my only complaint about the series is that its audio has never been as true to life as its physics. Many would agree. While it may have taken more than three generations to address, Gran Turismo 7 could be the first to tackle this weak spot of the series in a big way.
According to the LinkedIn profile of former Forza Audio Lead Mike Caviezel, he left Microsoft Studios to work for Polyphony Digital last month. He now serves as Senior Audio Lead for Polyphony Digital which is currently working on Gran Turismo 7.
