Pd-extended is a fork of Pure Data that integrates better with the OS, and provides an easy-to-install and thorough assembly of available libraries, extensions, and documentation. This is the final release, and is not maintained.

<em>IMPORTANT</em>: Running Pd-extended under Flatpak is experimental. The following are known limitations.

• Realtime priority cannot be used.
• JACK audio backend cannot be used.

Packages from https://puredata.info/ do not have these limitations.

Pure Data is an open source visual programming environment that runs on anything from personal computers to embedded devices (ie Raspberry Pi) and smartphones (via libpd, DroidParty (Android), and PdParty (iOS). It is a major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, etc), originally developed by Miller Puckette at IRCAM.

Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically without writing lines of code. Pd can be used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. It is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.
