I have some RGB LEDs (common anode) and I'd like to control them via sound from my stereo (line level). I'd like to be able to switch the two behaviors of the LEDs from flickering off when the input is high (LEDs always on), to flickering on when the input is high (LEDs always off). I've come up with the circuit below:
I'm wondering if I leave the emitter from the NPN and the collector from the PNP connected if I will see any adverse behavior? If so how could I fix this?
