Oculus just released a new version of their Spatializer VST/AAX plugin. In addition to providing the basic controls included with the standard VST or AAX plugins, it adds a VR interface allowing users to optionally visualize and manipulate sound parameters within VR, using either Oculus Touch or Xbox controllers. The sound locations of all Visualizer channels are visible with the HMD display. Users can change the position of sounds relative to the listener, adjust volume attenuation parameters, and enable/disable room and wall parameters within VR.
For more information and usage instructions, please refer to the PDF guide included with the Visualizer.
