What is MID?
MID is a digital language that was agreed upon by major manufacturers of Electronic Musical Instruments. It allows keyboards, synthesizers, computers, tape decks and even mixers & stage-light controllers to communicate with each other.

A MIDI file contains what the composer (or the person who played it) did at his/her music keyboard. It keeps track of which note (key) was pressed, when it was pressed, for how long, and at what pressure. Playing back a MIDI file would need a device (sound card) that can generate the sounds of common instruments (eg: Piano, Violins, Drums) on its own. The note data is sent to the device, which then generates the sounds that was intended. A MIDI file is generally very small and can be edited (including changing the instruments altogether) on any PC.

Standard MIDI files provide a common file format used by most musical software and hardware devices to store song information including the title, track names, and most importantly what instruments to use and the sequence of musical events, such as notes and instrument control information needed to play back the song. This standardization allows one software package to create and save files that can later be loaded and edited by another completely different program, even on a different type of computer. Almost every software music sequencer is capable of loading and saving standard MIDI files.

What is MP3?
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a digital audio encoding format using a form of lossy data compression. It is a common audio format for consumer audio storage, as well as a de facto standard encoding for the transfer and playback of music on digital audio players. MP3's use of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners, but is not considered high fidelity audio by audiophiles. An MP3 file that is created using the mid-range bit rate setting of 128 kbit/s will result in a file that is typically about 1/10th the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality. The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people. This method is commonly referred to as perceptual coding. It internally provides a representation of sound within a short term time/frequency analysis window, by using psychoacoustic models to discard or reduce precision of components less audible to human hearing, and recording the remaining information in an efficient manner. This is relatively similar to the principles used by JPEG, an image compression format.
