Pure Data is a programming environment for making sound, video and interactive art. Unlike traditional programming languages, Pd is graphical, where objects are connected to control the flow of information. Pd is easier—and more fun!—to use than text-based languages but more flexible than off-the-shelf solutions like sequencers, synthesizers and VJ programs. This makes Pd ideal for things like live audio-visual performance and interactive multimedia. No programming experience is necessary. We may be talking a bit of math, but we’ll be gentle.
