The iOS 15 beta revealed a new way for AirPods Pro and AirPods Max users to experience Spatial Audio, without the need for Dolby Atmos content. Called "Spatialize Stereo," the new feature will also work with macOS Monterey. According to 9to5Mac, this means that devices running those operating systems will be able to simulate spatial audio for non-Dolby content, detecting the movement of your head when you use AirPods to change the direction of sound. This means you should be able to play any song from Spotify, for example, and experience it in Spatial Audio, even if the streaming service doesn't support the format. The same goes for non-Dolby Atmos movie soundtracks, which means you'll only need a pair of AirPods Pro / AirPods Max and a compatible device to create an immersive home theater setup. While you might not get a true Dolby Atmos 3D audio experience, Spatialize Stereo should at least make sound seem like it's coming at you from different angles, making your movies, shows, and music more engaging. Previously, Spatial Audio support was limited to Dolby Atmos movies. So while I could use it with some titles from Apple TV Plus, Disney Plus, HBO Max, etc., many were incompatible. You'll need the beta version of iOS 15 or iPadOS 15 to try Spatialize Stereo, which is currently available to developers, with a public beta coming in July. If you have a compatible device running these operating systems, you can plug in your AirPods Pro or Max and start playing any content. Next, head over to Control Center and press and hold the volume slider; according to 9to5Mac, this will bring up the option to enable Spatialize Stereo.
