Explanation Of Terms - Denon DCD-2020AE Owner's Manual

Explanation of terms

A
Advanced AL32 Processing
Equipped with Advanced AL32 Processing, DENON's own analog
waveform reproduction technology.
The reproducibility of weak signals is enhanced by expanding 16 bit
digital data to 32 bit.
B
Bit rate
This is the amount of or audio data recorded on a disc that is read in
one second.
D
Dynamic range
The difference between the maximum, undistorted sound level and
the minimum sound level that is discernible above the noise emitted
by the device.
F
Finalizing
This process enables CD recorded with a recorder to be played by
other players.
L
Linear PCM
This is an uncompressed PCM (Pulse Code Modulation) signal. This is
the same system as the CD audio but uses 192 kHz, 96 kHz, and 48
kHz sampling frequencies on BD or DVD and provides higher sound
quality than CD.
M
MP3 (MPEG Audio Layer 3)
This is an internationally standardized audio data compression scheme,
using the "MPEG-1" video compression standard. It compresses the
data volume to about one eleventh its original size while maintaining
sound quality equivalent to a music CD.
CD
P
Pure direct
This function enables higher-quality playback of audio signals, by
turning off the display and digital output to eliminate any slight effect
they may have on the audio circuits.
S
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal)
at regular intervals and expressing the height of the wave at each
reading in digitized format (producing a digital signal).
The number of readings taken in one second is called the "sampling
frequency". The larger the value, the closer the reproduced sound is
to the original.
W
WMA (Windows Media Audio)
This is audio compression technology developed by Microsoft
Corporation.
To encode WMA files, only use applications authorized by Microsoft
Corporation. If you use an unauthorized application, the file may not
work properly.
