So Dolby Atmos works
Dolby Atmos is a hybrid format audio, especially for cinemas thought of. A speaker set-up in the home cinema we are showing you in the pictures gallery. Hybrid formats bring with them advantages and disadvantages. The approach works:
- Dolby Atmos combines a channel-based and object-oriented Audio source material.
- "Channel-based" means, for each speaker a separate audio track is included. Stereo, Dolby Digital, DTS, and Auro-3D are based, for example, channel.
- The disadvantage here is that the playback system must have exactly the same speakers, as in the case of the one who has created the audio content. Otherwise, you may suffer from localization and realism heavily.
- "Object-oriented" means that a sound source gets its own audio tracks. Meta-data to give then the desired Position or movement of the sound source. So a Mixer can generate in the playback system itself, the required loudspeaker signals.
- There are a lot of small drawbacks: firstly, the sound must be calculated either in real time or for each cinema individually pre-calculated.
- On the Other hand, the data to be transmitted are very large, for example, if instead of 7 discrete channels, 128 objects at a time should be played.
- This is done in the Dolby Atmos continue to be used mainly on the lossy AC-4 compression, which also comes with Dolby Digital.
- Dolby Atmos provides a special home cinema, with the directional speakers in the ceiling with sound. The reflection is then to create the impression of an elevated sound sources to the listener.
