All about MP3 files

MPEG-1 or mpeg-2 Audio Layer III, mostly known as mp3 or MP3, designates a format for coding digital audio data. MP3 still ranks among the most popular formats for storing audio data. In the early 80s, the German Fraunhofer Institut developed MP3 as a lossy format compared to Compact Disc Digital Audio (CDDA): Compression rate varies depending on parameterisation and goes up to 90 percent. Heavily compressed data proves highly advantageous when sending files over the internet.

MP3 compression represents the signal in frequency bands, eliminating practically inaudible bands. Great sound quality of music requires an average bitrate of 192 Kbit/s in stereo, at least, while mono suffices for voice-only signals. You would not want to scale up the bitrate of low-quality MP3 files as quality will not improve.
