Explanation of terms
B
Bit rate
This expresses the read amount per 1 second of video/audio
data recorded in a disc.
M
MP3 (MPEG AudioPlayer 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.
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.
Super Audio CD
There are three types of Super Audio CDs:
q Single layer discs
Single layer Super Audio CD with just an HD layer.
w Dual layer discs
Super Audio CD with a double HD layer, offering extended
playing time and high sound quality.
e Hybrid discs
Two-layer Super Audio CD with an HD layer and a CD layer.
The signals on the CD layer can be played on a regular CD
player.
Types of Super Audio CDs
Single layer disc Dual layer disc Hybrid disc
HD layer HD layer CD layer HD layer
• What is the HD layer?
The HD layer is a layer of high density signals for Super Audio
CDs.
• What is the CD layer?
The CD layer is the layer of signals that can be read on a
regular CD player.
W
WMA (Windows Media Audio)
This is audio compression technology developed by Microsoft
Corporation.
WMA data can be encoded using Windows Media® Player
Ver.7, 7.1, Windows Media® Player for Windows® XP and
Windows Media® Player 9 Series.
To encode WMA files, only use applications authorized by
Microsoft Corporation. If you use an unauthorized application,
the file may not work properly.
