Pure Data
What it is
Pure Data (Pd) is free software for building graphical programs that process audio and other media in real time. It runs on Windows, macOS, and GNU/Linux, with users combining processing elements in patch-based programs. Pd is used for audio and graphical processing, including work in visual arts, theatre, dance, audio, installations, performance, and media art. It can also control hardware and electronics or provide interfaces for other programs. Users can extend Pd through its built-in Deken package manager, which installs external libraries. Deken is mainly aimed at Pd vanilla but can also be used with some other Pd flavors, including Plug Data. Package listings identify availability for macOS, Linux, Windows, or source compilation; some packages are limited to specific architectures. To add an external, users can search for a library or object and install its downloaded DEK package through Pd's Find externals tool. The listed plan is free. The pages describe no paid tiers, trial terms, or usage limits.
