Audio Layer III

Audio Layer III, commonly known as MP3, is a digital audio compression format that reduces the file size of music and other sound recordings without significant loss of quality. Developed in the 1990s, it removes parts of the audio that are less perceptible to human hearing, allowing for efficient storage and streaming. This makes it easier to share music online and store it on devices like smartphones. MP3s became immensely popular due to their balance of sound quality and file size, changing how we consume music.
