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.
