In his long interview with Wired dedicated to PlayStation 5, Sony's Mark Cerny let slip a non-minor detail regarding the future generation of PlayStation consoles and the strain chosen by the PS5 designers to shape the next-gen vision.
As specified by Cerny, the PS5 technical specifications will also include a AMD chip with a custom unit which will be dedicated exclusively to 3D audio .
This arrangement, apparently "useless" for the purpose of the gaming experience offered by the new Sony console, was made necessary for a rather simple reason: according to the designer and programmer of the Japanese technology giant, in fact, "as a player it was a bit frustrating to see that not much has changed in audio from PlayStation 3 to PlayStation 4. With the next console our dream is that or to show how dramatically different the audio experience offered to enthusiasts can be if we apply a significant amount of hardware power to such processes ".
This chip should apply the Ray Tracing technology to the 'audio, as Mark Cerny himself suggests, stating that "if you want to conduct tests to see if the player can hear certain audio sources or the steps of the enemies, then ray tracing becomes a really useful tool because the audio behaves in a similar way, it projects rays that cross the environment and interact with it ".
Also during this interview, Sony's programmer confirmed that PS5 will not be released in 2019, which will be completely backward compatible with PS4 (and perhaps also with PS3, PS2 and PSX) and which will allow the use of the current PS VR viewer.
