What is MP3?
MP3 changed the world of digital music by making it possible to store thousands of songs on portable devices. It achieves this by removing audio frequencies that humans can't easily hear.
At 128 kbps, an MP3 file is about 1/10th the size of the original CD audio. Higher bitrates (256-320 kbps) offer near-CD quality while still being compact enough for portable use.
