MP3 (MPEG Audio Layer 3)

An audio storage protocol that stores music in a compressed format with very little loss in sound quality.

MP3 is the most common MPEG format for audio files. MP3 files can be played using the music player of the mobile phone or set as a ringtone. MP3 is commonly used on the Internet, on PCs, and on portable devices, including dedicated music players and phones with music player functionality.

Unlike some formats, MP3 files usually do not include DRM technology that would limit playback and sharing.

MP3 files can be created at different "bit rates". Higher bit rates offer better sound quality, but also increase file size, requiring more memory space to store.

Sharing is happiness:
