A widely supported lossy audio format. Higher bitrates generally preserve more sound detail.
Technical details
MPEG Audio Layer III encodes frames with psychoacoustic frequency-domain coding; frames carry synchronization and side information. [1]
Background and compatibility
The Library of Congress documents MP3 as a perceptual audio format whose compact files became broadly interoperable across players and services. [1]
