Stereo spatializer based on the SSpat module in AudioMulch
This is a stereo spatializer based on the SSpat module in AudioMulch. Hook up an audio input and optionally a Gate. Then send the outputs L and R to your output and rvL and rvR to the reverb unit of your choice (reverb unit should be set to fully wet for full effect). Record a path along which your input sound travels. You can adjust velocity, amount of Doppler shift, size of the field, amplitude attenuation, stereo separation, high-frequency absorption, reverb send amount, reverb send scaling.
Please let me know if you have suggestions for improvement.
