With the release of iOS 18, Apple has upgraded its AirPlay streaming technology to support the Spatial Audio format. Wireless listening in CD quality is now compatible with Dolby Atmos for unprecedented immersion in music, films and TV series.
Dolby Atmos in AirPlay
Launched in 2010 with iOS 4.2, then updated in 2017 with AirPlay 2, which introduced the multi-room functionality, AirPlay has established itself over the years as one of the most popular streaming protocols. It offers a number of advantages, including ease of use and transmission quality far superior to that of Bluetooth, with CD-equivalent resolution (16-bit/44kHz). Until now, however, AirPlay streaming has been limited to stereo, restricting its use for Spatial Audio encoded tracks available on Apple Music and multichannel movies. iOS 18 has unlocked new possibilities, with full support for Spatial Audio in AirPlay. Dolby Atmos streaming can now be carried out from an iPhone or iPad to an Apple Homepod speaker or any other Spatial Audio-compatible AirPlay device.
What is Spatial Audio?
Introduced in 2021 on Apple Music, Spatial Audio is the name given by the Cupertino firm to recordings mixed in Dolby Atmos. This format creates a three-dimensional soundscape by distributing sounds all around the listener. The experience is worthy of a real concert. Spatial Audio can also be integrated into movies viewed on Apple devices for a more immersive sound experience. Thanks to AirPlay support for this technology, it will now be possible to enjoy this immersive experience with a connected speaker, a connected amp or a network player compatible with AirPlay and Dolby Atmos.
With the release of iOS 18, Apple has taken another step forward by making its AirPlay technology compatible with Spatial Audio and Dolby Atmos. This advance consolidates AirPlay as the must-have broadcast protocol, now offering the possibility of an immersive, three-dimensional sound experience, whether you’re listening to music, or watching movies and series.
