Uses specially-produced Dolby Atmos surround tracks with on-screen 3D graphics

Designed by guitarist and immersive audio producer Jeff Perrin as a means to confirm the integrity of various surround systems while producing surround sound music tracks.

NOTE: Playback of test content on speakers requires an Apple TV (or similar AirPlay-compatible streaming device) connected to a Dolby Digital-compatible home theater system. Spatial audio support over headphones requires compatible iOS device with Dolby Atmos-compatible AirPods or Dolby Atmos-compatible headphones. When played back over an optical connection or non-Atmos devices, surround content will fold down to Dolby Digital 5.1 or stereo 2.0 format, depending on device capabilities. In all cases, a fast internet connection is highly recommend.

*Playback of Dolby Atmos content on non-Apple devices requires that the device supports multichannel audio (ie. Dolby Digital 5.1 or Atmos) over AirPlay 2. Please check your device specifications. Please try out the free included test tracks so as to ensure compatibility with your hardware before making any purchases.
