Brief introduction about MP3
MP3 (MPEG Layer-3) is a digital audio compression algorithm that achieves a compression factor of about twelve while preserving the original sound quality. It does this by optimizing the compression according to the range of sound that people can actually hear. MP3 is currently the most powerful algorithm in a series of audio encoding standards developed under the sponsorship of the MPEG organization and formalized by the ISO.
The widespread use of MP3
MP3 files (file extension ".mp3") can be downloaded from many World-Wide-Web sites and can be played back using software available for most operation systems, such as: Winamp for PC, MacAmp for Machintosh, MPEG-123 for Unix, etc.. MP3 files are usually downloaded completely before playing but streaming MP3 also is possible. A program called "ripper" can be used to copy a selection from a music CD onto your hard disk and another program called "encode" can convert it to MP3 file.
