MP3 is a revolutionary digital audio format developed by Fraunhofer-Gesellschaft and Thompson Multimedia in the late 1980s and brought to the mainstream through the Internet in 1997. MP3 is short for MPEG (Moving Pictures Experts Group) Layer - 1 , the group that help make MP3 an international standard.
MP3 is a compressed audio format that allows for smaller file sizes with similar sound quality to PCM WAV format, the format found on normal music CDs you would buy in a store.
MP3 is a type of audio codec where processed by significant compression from the original audio source with very little loss in sound quality. The compression up to 12:1 produces a very little degradation. Tighter compression can be achieved, but it will effect in sound degradation results.
To obtain certain compression, we must adjust the bit rates. The standart bit rates (near cd quality result) is 128 or 112 kbit/s. Many people claim that low-rate MP3 files sound better than Real Audio files with similar bit rates.
The advantage of MP3 is that it can be broken up into pieces, and each piece is still playable. The feature that makes this possible (headerless file format) also means that MP3 files can be made to stream across the net real-time (assuming the playback bitrate and speed of the Internet connection are compatible).
The popularity of MP3 comes from its practical uses. Music tracks in WAV format are extremely large in file size, averaging around 50MB in size. Si ...
