Specialized glossary
MP3
Abbreviation for“MPEG Audio Layer 3”.
A technical standard for audio
compression as decided by an ISO
(International Organization for
Standardization) MPEG working group.
Use of MP3 allows for audio data to be
compressed to approximately a tenth of
the source data size.
ISO 9660
An international standard for logical
formatting of CD-ROM files and folders.
It is divided into three separate levels
based on differences in file naming
procedures, data configuration and other
characteristics.
Multi-session
A session is the complete amount of data
recorded from the beginning to the end of
a single period of CD-ROM, CD-R/CD-
RW data recording. Multi-session refers to
the existence of data from two or more
sessions on a single disc.
Sampling
Refers to the process of encoding analog
audio data at regular intervals and
converting it to digital data. The sampling
rate refers to the number of times a
sample is taken in one second and is
expressed in Hz units. Increasing the
sampling rate improves the sound quality
but also increases the data size.

Bit rate
Refers to the volume of data per second,
expressed in bps (bits per second).
Generally, the larger the number of the
transfer bit rate when compressing an
MP3 file, the more information regarding
musical reproduction it carries, and
therefore the better the sound quality.
Packet writing
A general term for the method, similar to
that used for floppy discs or hard drives,
of recording the required file in a single
increment on a CD-R and similar.
ID3 Tag
ID3 tag is a method for storing
information related to the music in an
MP3 file. Information such as track, artist
and album name can be stored. This
content can be freely edited using ID3
editing function software.
VBR
Abbreviation for Variable Bit Rate. While
CBR (Constant Bit Rate) is generally
used, VBR varies the bit rate for audio
compression according to compression
conditions and this allows for
compression with preference given to
sound quality.
qOperating Tips for WMA
WMA is short for Windows Media Audio
and is the audio compression format used
by Microsoft.
Audio data can be created and stored at a
higher compression ratio than MP3.
