With the upcoming console generation, Astro Gaming is adapting to the changing technologies. One of the biggest shifts is that sound processing is done on the console. With the PlayStation 5, that’s done via the Tempest 3D AudioTech, and with the Xbox Series X, it’s done via custom audio hardware.

The difference lies in flexibility. With PS5, the Tempest chip reportedly does most of the work so that it works uniformly. Meanwhile, the Xbox Series X has its own audio solution that supports more Dolby Atmos, DTS:X and Window Sonic, but at the same time, users may need headset hardware that supports all those standards across different games.
