Spatial audio technology uses a combination of crosstalk cancellation, head related transfer function, and beamforming. The challenge has been to develop techniques suitable for small arrays which will yield subjectively better results than using stereo alone, and apply those in a manner that use several speakers without requiring complex algorithmic …

Announced just last year, and introduced in the latest AirPods devices, spatial audio makes use of specially developed algorithms in Apple's firmware to generate sound frequencies that create a 3D soundscape. The feature arrived as part of iOS 14 in September. Spatial audio works with video streaming apps that support 5.1, 7.1 and Dolby Atmos sound.
