Apple is rolling out a significant update for Apple TV that will please home theater enthusiasts. The latest tvOS 18.5 update brings a key enhancement to audio calibration, specifically designed to improve Dolby Atmos surround sound performance.
At the heart of this update is an upgrade to the Wireless Audio Sync feature, first introduced in 2019. This tool uses your iPhone’s microphone to help align audio and video output for a more cohesive viewing experience. With tvOS 18.5, Apple has refined this feature further by allowing it to sync Dolby Atmos audio over both AirPlay and Bluetooth connections.
Why is this important?
In many home theater setups, especially those using wireless speakers or soundbars, audio latency can become an issue—where sound is slightly out of sync with the visuals. The updated feature detects and corrects these delays, ensuring that Atmos-powered audio is tightly aligned with what’s happening on screen. This leads to a more immersive and accurate soundstage, especially for movies and shows that rely heavily on spatial audio cues.
Whether you’re using a pair of HomePods or a third-party Dolby Atmos setup, the improved calibration ensures better harmony between your Apple TV and audio gear. It’s a small but impactful update that demonstrates Apple’s continued focus on refining the home entertainment experience. If you’re an Apple TV user with a Dolby Atmos system, this update is well worth installing.
