Because 3D audio is stereo-based instead of channel-based (the system used in surround sound that uses an array of speakers to deliver varying audio tracks) all you need is a pair of standard stereo headphones to experience it. “It's basically stereo, but it uses specialized filters to mimic the sensation of sound coming behind you,” Hendricks explains. ![]() And - arguably most importantly - it can do this without need for any fancy gadgets in your console set-up. ![]() But the PS5 can bring that sense of audio immersion to regular games, not just VR experiences. As such, Sony’s PSVR headset comes with its own dedicated audio processor a device that is essentially the precursor to Tempest Engine. 3D audio is vital for creating a sense of immersion in virtual reality games. But 3D audio is about positioning individual sound-emitting objects - multiple hundreds of them, potentially - within a ‘sphere’, which provides an accurate sensation of direction, depth, and distance. Surround sound systems, such as 7.1 speaker arrangements, can help enhance that sensation. You can tell if the sound is coming from your left or right, or if they’re in front or behind you. “And obviously you as a listener, you'd be right in the middle of that sphere, basically.” Currently, most games use an audio system that places sounds in a ‘circle’ around you. Whereas with 3D audio, you are going to get that sense of space and directionality, which you wouldn't get from traditional panning that we usually use in the games industry.” “It's like we have a sphere of sound that we can place sounds in,” adds Hendriks. “So, when you sounds in a game, you're not going to be able to hear it above you or below you.
