Description
MIDI, or Musical Instrument Digital Interface, is a standard protocol for interconnecting and communicating musical information between digital devices. MIDI files are a type of digital audio file that store musical data in a standardized format, and they can be used for storing, playing, and sharing musical compositions and performances. MIDI files do not contain actual audio data, but rather they store instructions for how to play a musical piece, including information about the pitches, durations, and dynamics of the notes. MIDI files can be played using a MIDI player or synthesizer, or they can be converted to other audio formats using a MIDI converter.
An MP3 file is an audio file saved in a compressed audio format developed by the Moving Picture Experts Group (MPEG) that uses "Layer 3" audio compression. It is commonly used to store music and audiobooks with near-CD quality sound (stereo, 16-bit) and roughly 1/10 the size of a .WAV or .AIF file.
