Hi, I am looking to build a basic spectrum analyzer (if that is what you would call it) out of some LED lights for a car stereo. Basically, I want about 8 - 10 bars (for different frequency bands), and I want them to jump up and down to the music, giving it a direct feed off of the car stereo head unit.

circuit28. Joined Apr 13, 2018. 9. Apr 21, 2018. #1. Hello, I decided to build an LED audio spectrum analyzer and I want to know if I'm going in the right direction to get it to work. The simulation tool I have available (multisim) does not have the LM3916 and I have been unable to find a way to add it to its library so I drew out the diagram.
