{{Short description|API for controlling multimedia peripherals}}
The '''Media Control Interface''', — '''MCI''' infor short, — is an aginga high-level [[API]] developed by [[Microsoft]] and [[IBM]] for controlling [[multimedia]] peripherals[[peripheral]]s connected to a [[Microsoft Windows]] or [[OS/2]] computer, such as [[CD-ROM]] players and audio controllers.

MCI makes it very simple to write a program which can play a wide variety of media files and even to record sound by just passing commands as [[string (computer science)|string]]s. It uses relations described in Windows registries or in the [MCI] section of the file SYSTEM{{mono|system.INIini}}. One advantage of this API is that MCI commands can be transmitted both from the programming language and from the scripting language (open script, lingo aso). Example of such commands are ''{{mono|mciSendCommand''}} or ''{{mono|mciSendString''}}.

For{{As aof number| of2011 | alt = After a few years}}, the MCI interface has been phased out in favor of the [[DirectX]] APIs first released in 1995.<ref>{{cite book|title=Multimedia Technologies|isbn=9780070669239|pages=55|url=https://books.google.com/books?id=p2tFpmqQ7zMC&q=MCI+DirectX&pg=PA55|access-date=2017-11-29|date=2010|author1=Banerji|publisher=McGraw-Hill Education (India) Pvt Limited }}</ref>

== MCI Devices ==

The Media Control Interface consists of 47 parts:

*cdaudio

*AVIVideo

*digitalvideo

*CDAudio

*overlay

*Sequencer

*sequencer

*WaveAudio

*vcr

*videodisc

*waveaudio

Each of these so-called MCI devices (e.g. [[CD-ROM]] or VCD player) can play a certain type of files, e.g. {{mono|AVIVideo}} plays {{mono|.avi}} files, {{mono|CDAudio}} plays cd[[CD-DA]] tracks among others. Other MCI devices have also been made available over time.
