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.

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.
