'''Pure Data''' ('''Pd''') is a [[visual programming language]] developed by [[Miller Puckette]] in the 1990s for creating interactive [[computer music]] and [[multimedia]] works. While Puckette is the main author of the program, Pd is an [[open-source software|open-source]] project with a large developer base working on new extensions. It is released under [[BSD licenses|BSD-3-Clause]]. It runs on [[Linux]], [[MacOS]], [[iOS]], [[Android (operating system)|Android]] and [[Windows]].  Ports exist for [[FreeBSD]] and [[IRIX]].

Pd is very similar in scope and design to Puckette's original [[Max (software)|Max]] program, developed while he was at [[IRCAM]], and is to some degree interoperable with Max/MSP, the commercial predecessor to the Max language. They may be collectively discussed as members of the Patcher<ref>Puckette, M. (1988). The patcher. In Proceedings of International Computer Music Conference.</ref> family of languages.

With the addition of the [[Graphics Environment for Multimedia]] (GEM) external, and externals designed to work with it (like [[Pure Data Packet]] / [[PiDiP]] for Linux, {{nowrap|Mac OS X}}), [[framestein]] for Windows, [[GridFlow]] (as n-dimensional matrix processing, for Linux, {{nowrap|Mac OS X}}, Windows), it is possible to create and manipulate video, [[OpenGL]] graphics, images, etc., in realtime with extensive possibilities for interactivity with audio, external sensors, etc.

Pd is natively designed to enable live collaboration across networks or the Internet, allowing musicians connected via LAN or even in disparate parts of the globe to create music together in real time. Pd uses [[FUDI]] as a networking protocol.
