What is an MP3 file?

An MP3 file (MPEG-1 Audio Layer 3) represents one of the most revolutionary audio compression technologies ever developed. Created by the Moving Picture Experts Group (MPEG) and first released in 1993, MP3 fundamentally transformed how we store, share, and consume digital music by achieving remarkable file size reductions while maintaining acceptable audio quality.

Using sophisticated psychoacoustic modeling and lossy compression algorithms, MP3 can reduce audio file sizes by up to 90% compared to uncompressed formats. This breakthrough technology analyzes human hearing limitations to remove inaudible frequencies and redundant audio data, creating the foundation for the digital music revolution and enabling the rise of portable music players, streaming services, and online music distribution.
