■ PCM (Linear PCM)
Linear PCM is a signal format under which an analog
audio signal is digitized, recorded and transmitted without
using any compression. This is used as a method of
recording CDs and DVD audio. The PCM system uses a
technique for sampling the size of the analog signal per
very small unit of time. Standing for “pulse code
modulation”, the analog signal is encoded as pulses and
then modulated for recording.
■ CINEMA DSP
Since the Dolby Surround and DTS systems were
originally designed for use in movie theaters, their effect
is best felt in a theater having many speakers and designed
for acoustic effects. Since home conditions, such as room
size, wall material, number of speakers, and so on, can
differ so widely, it’s inevitable that there are differences in
the sound heard. Based on a wealth of actually measured
data, YAMAHA CINEMA DSP uses YAMAHA original
sound field technology to combine Dolby Pro Logic,
Dolby Digital and DTS systems to provide the visual and
audio experience of a movie theater in the listening room
of your own home.
■ SILENT CINEMA
YAMAHA has developed a natural, realistic sound effect
DSP algorithm for headphones.
Parameters for headphones have been set for each sound
field so that accurate representations of all the sound field
programs can be enjoyed on headphones.
■ Virtual CINEMA DSP
YAMAHA has developed a Virtual CINEMA DSP
algorithm that allows you to enjoy DSP sound field
surround effects without any surround speakers by using
virtual surround speakers.
It is even possible to enjoy Virtual CINEMA DSP using a
minimal two-speaker system that does not include a center
speaker.
