OpenDSP is a Realtime Operational System aimed for audio and video Digital Signal Processing on embeded devices like raspberry or headless personal computers.

OpenDSP Service is a Framework to create DSP gears that can fully interface with any MIDI or OSC compilant device. The source code are in python and is avaliable at:

The OpenDSP OS and Service together gives you the power to emulate a lot of different expensive proprietary DSP machines or to create your self a new one for your needs.

Achieve professional realtime low-latency audio and video processing on low budget computers!

OpenDSP is Good for:

  • Musicians
  • DJs
  • Audio and Video Producers
  • Video Art Producers and Performers
  • Multimedia Interactive Instalations
  • Theatre Sound Technicians
  • DSP Students and Researches

You can, for example, emulate a legendary Akai MPC or a Yamaha DX7 synthesizer, you can use it as as DJ system with or without vinyl timecode support. You can use it as a effect box and emulate classics like Roland Space Echo delay machine. You can use it as a mixing platform with support to the most common daily audio engeneering tools like compressors, limiters, expanders, multiband equalizers and so on...

The opensource community gives you a very huge number of different applications that

Pre release

This pre-release is fully functional and quite stable, the image avaliable on the link above:

Download Raspberry PI2 and PI3 0.11

OpenDSP Apps

OpenDSP application is a sub-set of N applications with a predefined state relation between then called Mod.

A Mod can have any number of applications and audio/video connections between then as far as you processor can handle it all.

By merging different applications you can achieve different kinda of DSP tasks to use as a standalone dedicated audio/video gear in an automated way via MIDI and OSC protocols or via common mouse/keyboard and monitor desktop station.

You can write your own Mod with a very few lines of configuration, just check some examples at mod/ directory of user data partition.

Examples can be found inside data/ directory.

App main interface

By making use of Mod config files you can define your own with a few lines of configuration

On the above example you setup a standalone tracker with visualization responds to audio on your screen and a keyboard used as a midi controller to play some sunvox synthesizers.
