Pure Data

Pure Data (Pd) is a real-time graphical programming environment for audio, video, and graphical processing. Developed by Miller Puckette, Pd allows users to create interactive computer music and multimedia works through visual patching. Algorithmic functions are encapsulated in 'objects' placed within a 'canvas,' connected by 'patch cords' for data flow. Pd supports core vanilla objects, external objects (written in C/C++), and abstractions (patches loaded as objects), enabling expansion of its capabilities. Notable flavors include Pd-vanilla, Pd-ceammc, Pd-L2Ork, Purr Data, and plugdata, each offering variations in UI and included libraries. Pd integrates with hardware via MIDI and OSC, making it suitable for embedded systems and large-scale installations. Its open-source nature fosters community contributions, ensuring continuous development and a diverse ecosystem of extensions.
