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 on headphones.

■

S-video signal

With the S-video signal system, the video signal normally 
transmitted using a pin cable is separated and transmitted 
as the Y signal for the luminance and the C signal for the 
chrominance through the S-video cable. Using the S 
VIDEO jack eliminates video signal transmission loss and 
allows recording and playback of even more beautiful 
images.

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 two-speaker system that 
does not include a center speaker.

■

WAV

Windows standard audio file format, which defines the 
method of recording the digital data obtained by 
converting audio signals. It does not specify the 
compression (coding) method so a desired compression 
method can be used with it. By default, it is compatible 
with the PCM method (no compression) and some 
compression methods including the ADPCM method.

WMA

An audio compression method developed by Microsoft 
Corporation. It employs the irreversible compression 
method, which achieves a high compression rate by 
thinning out the data of hardly audible part to the human 
ears. It is said to be capable of compressing the data 
quantity by about 1/22 (64 kbps) while maintaining a 
similar audio quality to music CD.
