What is Object Based Audio?
With traditional audio technologies, which channels (speakers) 
should output what types of sounds when creating audio sources 
was pre-defined. This is called “channel-based audio”. In contrast, 
new audio systems such as Dolby Atmos use a new technology 
called object-based audio. This technology processes each sound 
(e.g., the sound of a car or an actor’s voice) contained in an audio 
source as an “object” and memorizes each object's sound changes 
and positional changes in a sound field to control these changes 
during playback. The greatest advantage of applying object-based 
audio to a home surround sound system is the power to control the 
audio output method based on device features and the number of 
speakers used for playback. The unit adjusts sound beam output 
according to the listening room setup. It calculates the movements of 
an object according to each playback environment and reproduces 
sound fields that best match the intentions of a sound director. It also 
enables audio output in the vertical direction so that each sound 
(object) in an audio source can freely move within a sound field.
Yamaha’s Audio Technologies
This unit features many more functions based on Yamaha’s superior 
audio technologies.
This technology enhances and extends bass and treble, which tend 
to be weak in digitally compressed formats such as MP3 used with 
portable digital audio players and computers. This makes 
compressed audio sound more musically dynamic.
This technology enables precise digital recreation of actual acoustic 
environments found in well-known concert halls and movie theaters. 
This is achieved using Yamaha’s exclusive sound field programs, 
which are based on data measured in various sound fields, and with 
which the amplitude, depth, and volume of sounds have been 
adjusted.
CINEMA DSP 3D uses three-dimensional sound field data, including 
vertical directional information, and further extends standard 
CINEMA DSP, to make sound field effects more realistic and 
three-dimensional.
