SuperCollider – a programming language for real time audio synthesis and algorithmic composition. The language interpreter runs in a cross platform IDE (OS X/Linux/Windows) and communicates via Open Sound Control with one or more synthesis servers. The SuperCollider synthesis server runs in a separate process or even on a separate machine so it is ideal for realtime networked music.
Jack – Have you ever wanted to take the audio output of one piece of software and send it to another? How about taking the output of that same program and send it to two others, then record the result in the first program? Or maybe you’re a programmer who writes real-time audio and music applications and who is looking for a cross-platform API that enables not only device sharing but also inter-application audio routing, and is incredibly easy to learn and use? If so, JACK may be what you’ve been looking for.

Pd-Extended – Pure Data (aka Pd) is an open source . Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically, without writing lines of code. Pd is 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. Pd is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.
