I've included four versions in each format, so you can see which files play best on a variety of different computer systems.
Compression is fundamental to the delivery of multimedia content.
It enables us to create more with less. For example, one minute of raw CD-quality audio requires 11MB of storage. This same file can be compressed to less than 15 percent of its original size without any noticeable loss in audio fidelity. In fact, the same file can be compressed to as little as one percent of its original size while still maintaining superior audio quality. Users can now download five minutes of high quality music over a 28.8K modem in as little as five minutes.
