x Dolby Digital
Digital audio encoding/decoding technology
developed by Dolby Laboratories, Inc. It
consists of front (L/R), center, surround (L/R)
and sub-woofer channels. It is a designated
audio standard for DVD-video and also known
as 5.1ch surround. Since surround information
is recorded and reproduced in stereo, more
realistic sound with fuller presence is
delivered than with Dolby surround.

x Dolby Pro Logic II
This technology converts 2ch stereo recorded
audio into 5.1ch for playback. There is a
MOVIE mode for movies and MUSIC mode
for stereo sources such as music. Old movies
encoded in the traditional stereo format can be
enhanced with 5.1ch surround sound.

Digital audio encoding/decoding technology
for theaters developed by Digital Theater
Systems, Inc. It compresses audio less than
Dolby Digital, delivering a higher quality
sound reproduction.

x Sampling frequency
To convert analog audio to digital, analog data
should be quantified. This process is called
sampling, and the number of times per second
the analog data is quantified is called the
sampling frequency. A standard music CD
stores data quantified at 44,100 times per
second, which is expressed as a sampling
frequency of 44.1 kHz. Generally speaking, a
higher sampling frequency means better sound
quality.
