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 M4A file is an audio file created in the MPEG-4 format, a multimedia container format used to store compressed audio and video data. It contains audio encoded with either the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC).
