What is Apple Spatial Audio?

Apple has finally revealed the latest AirPods Pro 2 during its Far Out event, and amongst some new features, they now include Apple Spatial Audio.
Apple introduced spatial audio back at WWDC 2020, and at WWDC 2021 it revealed that Spatial Audio would work in conjunction with Dolby Atmos, giving Apple Music subscribers the option to listen to selected songs with the audio technology.
But now, Apple has announced that the latest Apple AirPods Pro 2 will feature Spatial Audio, alongside some new features. But what is spatial audio and how does it work?
What is Apple Spatial Audio?
Spatial Audio is a 3D audio technology that creates a more immersive soundscape with compatible Apple products by using dynamic head-tracking for a ‘theatre-like’ experience.
With Spatial Audio, Apple says that sounds can be placed “virtually anywhere” in the hemisphere. The technology works with 5.1 and 7.1 soundtracks, as well as Dolby Atmos object-based audio.
How does Spatial Audio work?
Spatial Audio with dynamic head-tracking uses the accelerometer/gyroscope in iOS devices in combination with directional audio filters and subtle adjustment of the frequencies that each ear receives to place sounds “virtually anywhere” within a hemisphere of sound.
The effect is to immerse the listener with effects all around them. And as the sound field stays mapped to the iOS device through the dynamic head-tracking functionality, when you move your head, “the voice stays with the actor or action on-screen.”

Spatial Audio with Dolby Atmos works differently in that there is no head tracking. As a result, you don’t need a pair of Apple headphones to enjoy this version of the feature. In fact, any headphones will do.
Apple Music will default to automatically play Dolby Atmos tracks on all AirPods and Beats headphones that feature the H1 or W1 chip. To get Spatial Audio with Dolby Atmos working on any pair of headphones, you just need to enable Atmos to ‘always on’ in the settings.
What is Personalised Spatial Audio?

As WWDC 22, Apple announced an enhanced version of its Spatial Audio technology that will feature in iOS 16. Personalised Spatial Audio is said to enable an even more “precise and immersive listening experience”, by allowing iPhone owners to use the TrueDepth camera to tune the performance, especially for the user.
Spatial Audio for AirPods has been advanced to better understand the geometry between your head and ears to create a more focused presentation, and it is a feature that can be utilised using the AirPods Pro 2.
