Sony is vigorously developing audio through the PS5.
of PS5 With the inclusion of a dedicated hardware chip called the Tempest Engine, audio can be given more emphasis.
Sony realizes that audio processing has taken a step backwards on the PS4 compared to the PS3 and hopes to provide 3D audio to everyone using the PS5. This is where the Tempest Engine comes in. TempestEngine is a redesigned GPU computing unit inspired by the PS3's SPU. Its SIMD performance and bandwidth can be combined with eight PS4 CPU cores.
It can support hundreds of sound sources, such as simulating a single raindrop in a rainy or shower scene. Leading system architect Mark Cerny called it "locality" in his presentation, which also takes into account the precise shape of your ears and head, and takes you further into the virtual world.
Sony does this by scanning human ears, either through pictures (Cerny even joked that the user sent a picture of Sony or a video of the ear) or by placing the test subject in a special room to get an accurate head Ministry-dependent transfer function (HRTF) readings for their ears. This is obviously impossible for every player, so Seni came up with the idea of collecting ear pictures, but Sony will provide about five of the approximately HRTF profiles when the PS5 is released, and these graphics should cover more popular Ear shape.
Sony wants to have virtual surround sound on all its speakers, which is part of it, although the gold standard is still headphones. At launch, the headset will work with Tempest Engine-enabled games, but Sony is working to add support for standard soundbar, stereo speakers, and multi-speaker setups.
These are all exciting things, but it may take some time to become the standard. Sony knows this, and Seni said that at least one game developed for the PS5 gives players the option to use existing PS4-style sound processing.
