What is MID?

Alternative extension midi
Category Audio/Music file formats
Developed by Sequential Circuits, MMA (MIDI Manufacturers Association)
Mime type audio/midi


A MID (or MIDI) file describes music data in the Musical Instrument Digital Interface technical standard. Unlike other audio formats like MP3, it specifies the individual music notes, their duration and loudness, as well as the instruments used. Because of that, a MIDI file may sound differently on different systems.
In order to make it consistent, you can convert it to another audio format.
