Digital Audio Control Protocol (DACP) is a protocol used by iTunes and other audio player and server applications on Mac, Windows and Linux computers, enabling remote control by mobile devices such as iPhone and Android phones and tablet computers. By connecting the personal computer to loudspeakers the mobile device is used as a two-way remote control, allowing selection and control of music playback within a traditional listening environment such as a home or apartment.

Compliant DACP clients can connect to any DACP enabled server. Clients are available for multiple desktop and mobile platforms.

Compliant DACP servers can accept connections from any DACP client. Multiple compliant servers are available for Mac, Windows and Linux platforms.
