About MP3
MPEG-1 Audio Layer III
A lossy audio format developed largely at the Fraunhofer Institute and standardized as part of MPEG-1 in 1993. Its patents expired in 2017, and typical bitrates run from 128 to 320 kbps. Use it when audio has to play everywhere: car stereos, old MP3 players, any phone or browser.
