Gradrigo | Adam Sporka Home Page



Gradrigo can be used as a chiptune VST as well as a audio generator for video games. It deserves multiple introductions, depending on whom it is being introduced to, as it comes in a number of forms:

  • For musicians: Gradrigo is a VST3 plugin to your favorite DAW (currently running on Windows 10), offering a number of built-in presets, providing an ample scale of Atari-esque sounds from the late 1970s with the characteristic slightly-out-of-tune dirt which will make its tracks stand out in your mix.
  • For sound designers: Gradrigo allows reproducing the classic arcade-style sounds from the old-school game consoles. Your sounds can be made parametric and one can modulate another. In this way, Gradrigo is more expressive than FMOD Studio or Wwise.
  • For game developers: Gradrigo is an audio middleware which is capable of running inside your game. It is available as a DLL with interface for C++ and Unity. The pieces of code that define the sounds can be executed from your game or their playback may be modified in real time. Check Gradrigo Test Game for an implementation example.

Gradrigo is a minimalist programming language. A few lines of code make sound effects and musical instruments.
