AirPlay to gain Dolby Atmos support for third-party speakers Apple has announced that its wireless AirPlay system will be upgraded to support Spatial Audio with Dolby Atmos for HomePod and compatible third-party audio devices. Today, AirPlay – Apple's alternative to Google Cast – is limited to conventional stereo audio. This means that when you transfer music from an iPhone or iPad to speakers or a receiver with built-in AirPlay, you miss out on lossless quality and Dolby Atmos.
