Explanation

MP3 (MPEG Audio Layer-3) is the international standard format for compressed digital audio, developed by the Fraunhofer Institute in Germany. MP3 compression reduces audio file size by about 90% while maintaining reasonable quality, making it practical to store and transmit music digitally. This format revolutionized music distribution, enabling digital music players, online music stores, and streaming services.
