Apple Music Spatial Audio to achieve dynamic head tracking in the fall

[ad_1]

Apple is currently rolling out spatial audio and lossless audio for Apple Music, giving subscribers a more immersive and higher quality audio experience. Later this year, however, Apple will also bring dynamic head tracking to songs in the Apple Music catalog.

From the FAQ section of a newly updated Apple support document:

Is spatial audio with dynamic head tracking available for music?

We are excited to announce that Spatial Audio with Dynamic Head Sensing is coming to Apple Music in the fall. Dynamic Head Tracking creates an even more immersive experience for spatial audio. It brings music to life by delivering a sound that dynamically adjusts when you turn your head. And you can experience spatial audio with dynamic head detection on AirPods Pro and AirPods Max with a compatible iPhone or iPad.

When you consider Apple’s current implementation of dynamic head tracking, it’s not entirely clear how it will apply to music. In its existing form, dynamic head tracking can be experienced when watching videos on iPhones and iPads with headphones that support spatial audio, but it’s the video element that is key.

Spatial audio uses the gyroscope and accelerometer in the headphones and iOS device to track head movement and device position, comparing motion data, and then remap the sound field so that it remains anchored to the device even if the head moves.

Apple Music videos with spatial audio enabled already support dynamic head tracking this way, but since no visual element is involved when listening to the audio tracks, Apple presumably has a different implementation in mind that will create more depth. to the listening experience. Individual instruments and effects can get stuck in a virtual stage when you turn your head, evoking the experience of being in the audience at a live concert, for example.

So obviously it doesn’t make sense that Apple Music tracks support spatial audio with head tracking enabled. Imagine walking down the street wearing your AirPods Pro, it would seem like all the tools came from your coat pocket. – Tim Hardwick (@waxeditorial) May 19, 2021

Returning to this. It looks like vanilla * Apple Music tracks will actually somehow support dynamic head tracking this fall. https://t.co/lJta1Sj7qt – Tim Hardwick (@waxeditorial) June 8, 2021

Either way, Apple says Apple Music subscribers will be able to experience it for themselves “in the fall,” which is also when iOS 15 is released to the public, so the two may very well fall together.
