About mp3
MP3 is a popular digital
audio encoding and lossy compression
format
invented and standardized in 1991 by a team
of engineers working in the framework of the
ISO/IEC MPEG audio committee under the chairmanship
of Professor Hans Musmann (University of Hannover
- Germany). It was
designed to greatly reduce the amount of data
required to represent audio, yet still sound
like a faithful reproduction of the original
uncompressed audio to most listeners. In popular
usage, MP3 also refers to files of sound or music
recordings stored in the MP3 format on computers.
Overview
MP3
is a compression format. It provides a representation
of pulse-code modulation-encoded (PCM) audio data
in a much smaller size by discarding portions
that are considered less important to human
hearing (similar to JPEG, a lossy compression
for images).
A
number of techniques are employed in MP3 to
determine which portions of the audio can be
discarded, including psychoacoustics.
MP3 audio can be compressed with different bit rates, providing
a range of tradeoffs between data size and sound
quality.
The
MP3 format uses, at its heart, a hybrid transformation
to transform a time domain signal into a frequency
domain signal:
MP3 Surround,
a version of the format supporting 5.1 channels
for surround
sound, was introduced in December 2004.
MP3 Surround is backward compatible with standard stereo MP3,
and file sizes are similar.
In
terms of the MPEG
specifications, AAC (Advanced audio coding) from MPEG-4 is to be the
successor of the MP3 format, although there
has been a significant movement to create and
popularize other audio formats. Nevertheless,
any succession is not likely to happen for a
significant amount of time due to MP3's overwhelming
popularity (MP3 enjoys extremely wide popularity
and support, not just by end-users and software
but by hardware such as DVD and CD players).
Online
music resources
Tools
such as iRate
try to make it easier to find music that matches
the listener's tastes. There are several online music stores. Apple's iTunes store is presently the most popular commercial
online music offering. Independent artists are
able to use smaller sites to provide distribution.
A controversial MP3 portal is the Russian site
AllOfMP3.com,
which through their country's copyright laws
can legally distribute music by any label or
artist. The music industry has closed down many
file sharing networks and the publics urge for
free mp3 downloads has made the way for sites
as bestmp3links.com
and Erik Brown's MP3 Links that list links to
free legal mp3 download sites.
There
are also several online columnists who edit
news sites focused on digital music and the
grassroots community it spawned. They include
Richard
Menta's MP3 Newswire, an early MP3 news site started in 1998,
Jon Newton's P2Pnet,
and Thomas Mennecke's Slyck.com. Other sites like Download.com
and Vitaminic.com which
allow artists to choose to post their own music
for free download.

Online music store
An
online music store is an Internet service that sells audio, usually primarily music,
on a per-song and/or subscription basis. The
realization of the market for these services
grew widespread around the time of Napster, a music
and file
sharing service created by Shawn
Fanning that made a major impact on the
Internet scene during the year 2000. Some services have
tethered downloads, meaning that playing
songs requires an active membership.
In
2000 Sony became the first company to make music
from one of the major labels available for sale
on the Net. The big record companies were apprehensive
to license their catalogs to outside companies
and refused the late 90's requests of MP3.com
and Emusic
(then called Goodnoise)
to sell digital song downloads. They eventually
decided to start their own services, which they
could control directly.
Sony's
service turned out to be an ill-conceived affair.
Not only was the service difficult for consumers
to navigate and use, Sony's expensive pricing
of US$3.50 per song track turned off many early
adopters of the service. Furthermore, as MP3 Newswire pointed out in its review of the service,
users were actually only renting the tracks
for that $3.50. After a certain point the files
expired and could not be played again without
repurchase. The service quickly failed.
Undaunted,
the record industry tried again. Universal Music
Group and Sony teamed up with a service called
Duet, later renamed PressPlay. EMI, AOL/Time Warner and BMG teamed up with
MusicNet.
Again, both services struggled, hampered by
high prices and heavy limitations on how downloaded
files could be used once paid for. In the end,
consumers chose instead to flock to the free
file sharing programs, which were far more convenient
to use and free to boot.
Non-label
services like Emusic
and Listen.com (now
Rhapsody.com) sold the music of independent
artists to keep in the game, but it wasn't until
Apple Computer introduced iTunes
in 2003
that sales of digital downloads took off. Now
there are newer services that have started in
recent years, to continue selling the music
of independent artists. Two such sites are Independent
Music Online, Inc. and Magnatune.
