What is the MP3 file format?

MP3 is the world's most recognized audio format, using psychoacoustic compression to dramatically reduce file size while preserving perceptible sound quality. It became the foundation of digital music distribution.

MP3 (MPEG-1 Audio Layer III) is a lossy audio compression format standardized as ISO/IEC 11172-3. It uses psychoacoustic modeling to discard audio data that falls outside the range of human hearing perception, achieving compression ratios of up to 10:1 compared to uncompressed PCM audio. Developed by the Fraunhofer Society and officially released in 1993, MP3 revolutionized music distribution and enabled the rise of portable digital audio players, online music stores, and peer-to-peer file sharing. Despite newer formats like AAC and Opus offering better quality at lower bitrates, MP3 remains universally supported and widely used due to its unmatched compatibility across virtually every device, platform, and application.
