Aegean Music has released Doppler Dome, a free audio effect plug-in based on the Doppler effect.

Aegean Music Doppler Dome

In Doppler Dome, the center is the listener and the sound source moves along a path. Drag the dots to adjust the path’s bezier curves. The path can act like an LFO, or a loop. A midi note in message sent to the plugin will reset the path position to sync it with the project.

The Blend will mix the pitch effect with the dry signal, this is a bit like a chorus or modulated delay. The Pitch Scale knob determines how much pitch is affected, it can be turned off by setting it to zero. The Volume Scale Scale knob determines how much volume affected, based on distance. The Pan Scale Scale knob determines how much L/R position is affected, based on left and right position.

Doppler Dome is available to download for Windows and Mac (VST/AU).
