Revolution is a virtual surround / 3D audio effect. It allows the user to place a sound anywhere in 3D space, and to move that sound around in real time with the associated Doppler Effect.
Revolution will allow you to create complex echoes, Doppler effects and flybys with ease.
Free yourself from the limitations of stereo panning - now you can place sounds in front or behind the listener, or even below and above. Add an extra dimension to your mix!
