What is MIME type "audio/mid"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

audio/mid is a MIME type that marks files containing MIDI instructions instead of recorded audio. MIDI—short for Musical Instrument Digital Interface—stores commands that tell digital instruments what notes to play, how loud to play them, and when. Unlike sound recordings, these files require a sound generator to produce actual audio.

Files such as MIDI, MID, and RMI use this MIME type.

Use cases and key facts:

• Used in music production software and digital instruments.
• Commands control pitch, velocity, and other performance parameters.
• Files are lightweight and easy to edit.
• Common in game soundtracks and embedded system applications.
