PositiveGrid-Optical-Compressor
It provides a careful emulation of the original optical compressor now at component level: you can even change capacitors to enrich the overall sound. We even modeled the light source and detector behavior, so you can fine tune and get the perfect attack and release characteristics by changing the light source, light source age, light source sensitivity, attack, and release knob.
