MPEG Layer III

MPEG Layer III, commonly known as MP3, is a digital audio compression format that reduces the size of music files while preserving sound quality. It works by removing audio data that is less noticeable to human ears, making the files much smaller without significantly affecting how they sound. This efficiency allows for easy storage, sharing, and streaming of music on devices like smartphones and computers. MP3 revolutionized digital music by enabling high-quality sound in manageable file sizes, making it a popular and widely used format for audio playback and distribution.
