MP3's:
Catch the Wave in Portable Music
by my-tech-guide.com
Anyone with a computer, an Internet connection
and time can find and play MP3 sound files. It just takes some
patience.
There's
a symphony of sound on the Internet, and much of it is
stored in MP3 file format. MP3 files -- MP3 stands for MPEG
1 layer 3 -- are compressed, allowing for reasonably quick
downloading compared to other types of audio files, while preserving
quality sound.
Companies marketing MP3 technology use terms
such as "CD
quality" or "near-CD quality" to describe what
the music sounds like. It's more accurate to say that the quality
differs depending on how the file was created, and the highest
quality MP3 file is near CD-quality.
MP3s
are abundant on commercial music Web sites, and there
are stockpiles of illegal files stashed on pirate sites or
traded via newsgroups. MP3s can be played over the Internet
or downloaded to a computer and then played. The streaming
audio technique lets Internet listeners hear music as it's
sent from the site, eliminating the wait while files download.
Downloading
MP3 files is the most time-consuming part of the process. Theoretically, it should take about 21/2 minutes to
save a 1-megabyte file using a 56 kbps modem. So a five-minute
song should take about 12 minutes. But modems often don't connect
at the maximum speed because of line quality or modem configuration,
and that can drag out the process. Using a high-speed Internet
connection, such as a digital subscriber line, speeds up downloading
considerably, with songs taking only a few minutes.
Download speeds also depend on the speed of the server and
the amount of network traffic. High-end commercial sites, such
as mp3.com, usually have optimum download times, while pirate
sites usually are substantially slower. A 1-megabyte MP3 file
holds about one minute of high quality music or several minutes
of spoken words.
Saving TLC's song "I Need That" in MP3 format from
http://www.mp3.com/ at 28.8 kbps took about 21 minutes, while
downloading the song at 56 kbps took about 15 minutes. The
song, which is a previously unreleased track from the R&B
group's latest album, "FanMail," is 3.7 megabytes,
or 31/2 minutes long.
MP3
players come in two forms: the software kind that run
on computers, and the hardware kind that can connect to computers,
download music from the machine and then play the files independently.
Several free MP3 players can be downloaded from the Web, installed
and then used to open and play files, just like any other computer
program. Some solid MP3 players for computers with Windows
95, Windows 98 or Windows NT include Nullsoft's WinAmp, MusicMatch's
Jukebox and RealNetwork's RealJukebox.
All three can be downloaded for free, and MusicMatch Jukebox
and RealJukebox can also create MP3 files from audio CDs. MusicMatch
and RealJukebox also have enhanced versions with more features.
MacAmp is popular with the Apple computer crowd, and there's
a Macintosh version of RealJukebox, too.
Most MP3 players have a virtual boombox interface -- with
basic commands such as play, fast forward, rewind and pause
-- and some models also include a graphic equalizer and a playlist
that acts as a cue for songs.
After a player has been selected and downloaded from the appropriate
Web site, setting it up is usually just a matter of double
clicking the install icon and following a couple steps.
