Definition
MP3 is an audio file format. Audio files can be quite large,
which is why it hasn't been practical to store music on PCs.
An MP3 file is an audio file that has been compressed
(anywhere from one fifth to one seventeenth of its original
size) with little or no loss in sound quality, resulting in a great
sounding MP3 file small enough to be downloaded and/or
stored on your computer.
One of the main components of MUSICMATCH Jukebox is the
Recorder. This is where you record (also known as ripping
and encoding) your audio CDs to MP3.
Technically, ripping is the process of extracting the digital
audio files from a CD. This process is commonly referred to
as ripping CDs and this, in conjunction with the encoding
process, is known as recording within MUSICMATCH
Jukebox.
For our purposes, encoding is the process of compressing a
ripped audio file into MP3, AIFF or other audio formats. The
ripping and encoding processes happen in one easy step
within MUSICMATCH Jukebox and are collectively referred to
as Recording.
An encoder is a device that modifies information into a
required transmission format. For our purposes, an MP3
encoder is the technology used to compress ripped audio files
into the much smaller MP3 format. Within MUSICMATCH
Jukebox, the ripping and encoding processes are combined in
one easy step and are referred to as Recording.
MUSICMATCH Jukebox currently features the next- generation
encoder from Fraunhofer, the co- inventors of the MP3
format.
A decoder is a device necessary to play back information,
which has been modified (or encoded) to a specific
transmission format. For our purposes, MUSICMATCH
Jukebox features an MP3 decoder, more commonly referred
to as an MP3 player. We also decode, or play, MP2.
Encryption refers to the application of a specific algorithm to
data so as to alter the appearance of the data making it
