I recently built a 5 channel color organ from a kit. It receives sound modulation from a microphone, spits it into five frequency bands and modulates 120 Volt output to 5 proportionally illuminated lamps. I am using dimmable LED lamps but the amplitude variation is undesirably rapid. Most often the sound input produces an esthetically unpleasantly rapid flickering or strobe like effect. Consequently I am looking for a simple way to smooth the output variations. Perhaps putting a capacitor or choke between the output and the lamps. The maximum output voltage is 120 volts and the total wattage for each channel is less than 100 watts. An adjustable amount of "smoothing" would be desirable. Does anyone have a suggestion as to how I might accomplish this?
