ENGLISH
Cleaning discs
• If there are fingerprints or dirt on a disc, wipe them off before
using the disc. Fingerprints and dirt can impair sound quality
and cause interruptions in playback.
• Use a commercially available disc cleaning set or a soft cloth
to clean discs.
Gently wipe the disc from
the inside towards the
outside.
Do not wipe in a circular
motion.
NOTE
Do not use record spray, antistatic agents, benzene, thinner or
other solvents.
Explanation of terms
B
Bit rate
This is the amount of 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 CDs recorded with a CD recorder or
drive to be played by other players.
L
Linear PCM
This is an uncompressed PCM (Pulse Code Modulation) signal.
This is the same system used for CD audio but uses 192 kHz,
96 kHz, and 48 kHz sampling frequencies on Blu-ray Disc or
DVD and provides higher resolution than CD.
M
MP3 (MPEG Audio Layer 3)
This is an internationally standardized audio data compression
scheme, based on the “MPEG-1” video compression standard.
It compresses the data volume to about one eleventh its
original size while maintaining sound quality roughly equivalent
to a music CD.
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 the 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.
