CINEMA-DSP

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.
