■ Sampling frequency and number of
quantized bits
When digitizing an analog audio signal, the number of
times the signal is sampled per second is called the
sampling frequency, while the degree of fineness when
converting the sound level into a numeric value is called
the number of quantized bits.
The range of rates that can be played back is determined
based on the sampling rate, while the dynamic range
representing the sound level difference is determined by
the number of quantized bits. In principle, the higher the
sampling frequency, the wider the range of frequencies
that can be played back, and the higher the number of
quantized bits, the more finely the sound level can be
reproduced.
■ 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 using headphones.
■ Virtual CINEMA DSP
YAMAHA has developed a virtual CINEMA DSP
algorithm that allows you to enjoy DSP sound field
surround effects even without any surround speakers by
using virtual surround speakers.
It is even possible to enjoy virtual CINEMA DSP using a
minimal 2-speaker system that does not include a center
speaker.
