We are talking about Spatial Audio mode with Dolby Atmos support, which allows you to listen to music with surround sound in AirPods and Beats headphones with H1 and W1 chips. You can activate Spatial Audio in Apple Music settings.
The second innovation of the streaming service is support for Lossless Audio – lossless sound. To do this, Apple uses a proprietary ALAC (Apple Lossless Audio Codec) codec. Unfortunately, you won’t be able to test the new mode on wireless headphones. To do this, you have to connect a wired headset or use HomePod and HomePod mini smart speakers. Music with Lossless Audio support is displayed in the application with a special badge.
As a reminder, there is no need to pay extra for new functions. They are available to all Apple Music subscribers.
