# MIDI (Musical Instrument Digital Interface) support

> Discover how MIDI files transmit audio to web clients, with links to valuable resources in this guide.

This article discusses MIDI (Musical Instrument Digital Interface) files, which provide a way to send audio to web clients.

## About MIDI

MIDI files instruct a computer's sound card how to make a particular sound and send it to the speakers.

MIDI files are very small. A typical .wav file of a 5-minute song can be 20 megabytes or more. A comparable MIDI file of the same song can be less than 1000 kilobytes.

## Using MIDI

Hosting.com's servers have the appropriate MIME types configured for full MIDI file support. You can use the **.midi** or **.mid** extension for your MIDI files.
