Dolby Atmos TrueHD

Dolby Atmos is an encoded 24 bit, 48 kHz PCM audio format, which adds 4 channels of height information to 5 Channel and 7 Channel Surround Sound. It is often referred to as 5.1.4 Channel Immersive Audio or 7.1.4 Channel Immersive Audio (a reference to adding 4 height channels to 5 Channel, 5.1 Channel , 7 Channel or 7.1 Channel Surround Sound recordings).

Dolby Atmos introduces a Height dimension to movies and music, which transforms and augments their emotional impact. The Dolby Atmos format brings immersive 3D audio to music.

The Dolby Atmos TrueHD downloads from NativeDSD differ from those found on streaming music sites in that the TrueHD editions do not use the additional compression needed to stream a Dolby Atmos music track.

To hear the 4 height channels and the 5.1 or 7.1 Surround Sound audio in Dolby Atmos encoded files, the listener will need a Dolby Atmos decoder in their music system. The decoder is part of some newer Audio Video Receivers (AVR) or preamp/processors that support Dolby Atmos.

These AVRs and preamp/processors will include a Dolby Atmos decoder and will handle all of the necessary signal processing and rendering. You’ll find a growing selection from leading AVR and component manufacturers.

Without the Dolby Atmos decoder, the Dolby Atmos files will play as standard 5 Channel, 5.1 Channel, 7 Channel or 7.1 Channel Surround Sound. (The decoder is what provides 4 Dolby Atmos height channels).
