CINEMA-DSP SOUND FIELD PROGRAM
The sound design of CINEMA-DSP sound field programs
Filmmakers intend the dialog to be located right on the screen, the effect sound a little farther back, the music spread even farther back, and
the surround sound around the listener. Of course, all of these sounds must be synchronized with the images on the screen.
CINEMA-DSP is an upgraded version of YAMAHA DSP specially designed for movie soundtracks. CINEMA-DSP integrates the DTS,
Dolby Digital, and DOLBY PRO LOGIC surround sound technologies with YAMAHA DSP sound field programs to provide the surround
sound field. It recreates the most complete movie sound design in your audio room. In CINEMA-DSP sound field programs, Yamaha’s
exclusive DSP processing is added to the front left, center, and right channels, so the listener can enjoy realistic dialogue, depth of sound,
smooth transition between sound sources, and a surround sound field that goes beyond the screen.
When a DTS or Dolby Digital signal is detected, the CINEMA-DSP sound field processor automatically chooses the most suitable sound
field program for that signal.
Sound field images of the CINEMA-DSP programs
Each CINEMA-DSP program has its own type of sound field processing block. The sound field data, including the presence and surround
sound fields, are based on actual measured data. The presence and surround sound fields can be expressed in the distribution of virtual sound
sources and echo patterns. However, as these two types of sound fields are processed with complex elements such as energy balance and
mixing signal ratios, they are expressed as a sound field based on auditory perception.
