What Is A Sound Field - Yamaha AVENTAGE RX-A3050 Owner's Manual

CINEMA DSP
The excitement of a concert hall and the powerful sense of being inside a movie - we all want to enjoy these experiences in our own living room. Yamaha has pursued the fulfillment
of these desires for more than 20 years, and this fulfillment has now taken shape as the Yamaha AV receivers.

What is a sound field?

We perceive sound from a voice or an instrument not only as the sounds that are heard
directly but also as the "reflected" or "reverberant" sound that has been reflected by the
walls or ceiling of the building. The character of the reflected and reverberant sound is
affected by the shape, size, and material of the building, and all of these sounds taken
together are what give us the auditory sensation of being in that specific place.
This unique acoustical character of a specific space is what we call the "sound field".

CINEMA DSP/CINEMA DSP 3D
Yamaha has accumulated a massive amount of acoustical data by analyzing the actual
sound fields of concert halls and performance spaces around the world. "CINEMA
DSP" allows this data to be applied to create sound fields. This unit contains a wide
variety of sound programs using CINEMA DSP.
By selecting a sound program that is appropriate to the content of the playback source
such as movies, music, or games, you can maximize the acoustical effectiveness of
that specific content. (For example, a sound program designed for movies can give you
the sensation of actually being in that scene.)
In addition, the "CINEMA DSP 3D" function uses 3-dimensional sound field data that
includes the axis of height, generating an even more realistic sound field with a spatial
sense.

"CINEMA DSP HD " is Yamaha's flagship 3D sound field playback technology that
takes full advantage of the massive amount of acoustic reflection data included in the
sound field data. With support for rear presence speaker output, it delivers more than
twice as much capability for generating acoustic reflections as conventional CINEMA
DSP 3D, in addition to high-frequency playback capability, delivering an utterly natural
and powerful spatial sound field.
