MP3

The name of the file extension and also the name of the type of file for MPEG, audio layer 3. Layer 3 is one of three coding schemes (layer 1, layer 2 and layer 3) for the compression of audio signals. Layer 3 uses perceptual audio coding and psychoacoustic compression to remove all superfluous information (more specifically, the redundant and irrelevant parts of a sound signal. The stuff the human ear doesn't hear anyway). It also adds a MDCT (Modified Discrete Cosine Transform) that implements a filter bank, increasing the frequency resolution 18 times higher than that of layer 2.

The result in real terms is layer 3 shrinks the original sound data from a CD (with a bit rate of 1411.2 kilobits per one second of stereo music) by a factor of 12 (down to 112-128kbps) without sacrificing sound quality.


Because MP3 files are small, they can easily be transferred across the Internet.

MPEG -- Stands for "Motion Picture Experts Group". This is the standard for compressing and storing audio and video files on the Internet and transferring them to portable audio/video players.

MP4

May refer to the MPEG-4 technology in general or to its file structure, which uses the .MP4 extension. MP4 files are container formats that can hold a mix of multimedia objects (audio, video, images, animations, menus, etc.). See MPEG and MP4 player.

So it just takes it one step further

Also I believe MP3 only does Music but MP4 Does (audio, video, images, animations, menus, etc.).
