Efficient coding
techniques are today a must for the processing of audio and video
data with computers. A lot of progress has been achieved in the
recent years in this field. While there are several proprietary
formats for audio coding the ISO/IEC standardization body has
released an international standard recommended by the MPEG group
(Moving Pictures Experts Group, ISO/IEC IS11172-3 and IS
13818-3).
Non-coded audio means data processed with 8 or 16 bit linear data
words sampled with the sampling frequency (e.g. 44.1kHz for CDs).
This means that you end up with 1.4Mbit for one second of music
in CD quality. By using MPEG compression you can shrink down that
data by a factor of 12 and still gain CD-like quality. Factors of
up to 24 and more still allow for a quality significantly better
than just reducing linearily the sampling frequency and the
number of bits. This is realized by "perceptual coding"
techniques taking into account the limited resolution of the
human ear. *

If you want more info about mpeg3 you can visit www.layer3.org
There are a lot of
applications in the WWW which will let you play mpeg3 files.
Most used is WinAmp from Nullsoft. I suggest
you to go to www.mp3.com/players and take a look...
Now there are a
lot of cool programs that do all the job, all you have to do is
download the right program...
If you have a P166MMX+ I suggest you to see www.musicmatch.com they have a full
integrated program tha lets you make eveything you want with
mp3s...
A lot of Places...
