Purr Data

Purr Data is a visual programming language with an emphasis on generating sound, video, 2D/3D graphics, and connecting through sensors, input devices, and MIDI as well as OSC devices. It has an HTML5 frontend. It also has realtime DSP backend written in C which can run natively or in the browser.

Purr Data has a special emphasis on generating audio and/or video in real time, with low latency. Much of its design focuses on receiving, manipulating, and delivering high-quality audio signals. Specifically, the software addresses the problem of how to do this efficiently and reliably on general purpose operating systems like macOS, Windows, Debian, etc.-- i.e., systems designed mainly for multi-tasking.

Purr Data can easily work over local and remote networks. It can be used to integrate wearable technology, motor systems, lighting rigs, and other equipment. Purr Data is also suitable for learning basic multimedia processing and visual programming methods, as well as for realizing complex systems for large-scale projects.
