Spatial audio (Spatial audio) is a feature on recent iPhones and soon the AirPods Pro. With this, Apple simulates a surround sound from the speakers of your iPhone and in the AirPods Pro. Read everything you want to know about spatial audio here.
Since the iPhone 7, the iPhone has stereo speakers: one speaker is at the bottom right, the other above the screen in the ear speaker. If you hold your iPhone in landscape mode, you will hear the sound coming from both the left and right. But with spatial audio on the iPhone and AirPods Pro, it sounds even fuller and (as the name says) more spacious. Which Apple devices exactly work with spatial audio and what do you need for it?
What is Spatial Audio (Spatial Audio)?
There are all kinds of standards for creating good sound quality. For televisions and speakers, for example, there is Dolby Atmos. The Apple TV 4K supports Dolby Atmos, but the iPhones can also play such content. Such standards create surround sound, without having to place speakers all around you. Spatial audio on the iPhone and AirPods works much the same. It seems as if all kinds of sounds are heard from behind, above, below, left and right, while you only have two speakers. You are therefore right in the middle of the action, which can be useful especially with films. Another term that is often used is 3D audio.
Which Apple devices support spatial audio?
Spatial audio is available on a number of devices:
- iPhone 11
iPhone 11 Pro
iPhone 11 Pro Max
- AirPods Pro (from iOS 14)
From 2019, Apple has added spatial audio to the iPhone and from iOS 14 and the accompanying AirPods firmware update we also find this function on the AirPods Pro. Because you only have one speaker per ear with the AirPods Pro, Apple has made all kinds of algorithms that mimic the surround sound. Apple has also applied a special technique for the AirPods Pro. Because you move your head regularly, the sound turns with the AirPods. Apple uses the accelerometer and gyroscope to register movement with your head and thus link the sound to the position of your device. As a result, the sound coming from the left will always be heard from the left. Even if you turn your head to the left or right.
Spatial audio works with content encoded with 5.1, 7.1 and Dolby Atmos audio.
What are the benefits of spatial audio?
The biggest advantage is that it seems like the sound comes from all sides, without having to use multiple speakers. Films and documentaries therefore sound more realistic. Think of an action movie, in which a car comes tearing from the left back to the right front of the image. The sound then corresponds much more to the image.
Spatial audio has already proven itself on the iPhone. In a nature documentary on Netflix you really hear the jungle sounds around you, as if you are standing in the middle of a rainforest. Chirping birds, creaking branches and more sound a lot more realistic. The largest application is therefore with films and a lot less with music via streaming services.
There are actually no disadvantages on the iPhone. For example, it no longer consumes battery, so you don’t have to worry about your iPhone draining faster. Whether that also applies to the AirPods Pro is not yet known because the function is not yet available. Because more sensors are involved, this may have an impact. There is no switch to turn the function on or off.
The biggest disadvantage is that spatial audio is only available on a limited number of devices. Future iPhones and AirPods will most likely also support the Spatial Audio.
