PR speak. It sounds like virtual surround no matter how he phrases it.Interesting take you have and how it contrasts with Cernys
He made it sound as if the more speakers you have the harder it is to implement, with headphones being the gold standard
They briefly covered all uses for GPU RT in general that doesn't mean it doesn't support audio or graphics RT. Cerny first mentioned audio RT on wired interview
They are leaving it up to developers to implement raytracing
Good thing then that hadphones are the "gold standard" for 3D audio on PS5
From the video:
"virtual surround sound has a lot in common with 3D audio on headphones..."
Is he just use them interchangeably as synonyms or 3D audio is for headphones and virtual surround sound for speakers?
