This is a real time LED Audio Spectrum Analyzer. You can embed this unit in an audio system or use it as a stand-alone unit. The LED Spectrum Analyzer can display a real-time bar-graph spectrogram on a 20 x 20 LED display in four different ways. It produces very nice visual effects and simultaneously provides an effective observable way to inspect audio performance during …

What you have in post #1 is linear. About 0.6 volts / LED. That is fine for measuring voltage. For audio we normally use a log meter. (3bd/LED) This IC is what your are building. (I know you don't have the part but...) The LM3914 is linear and the LM3015 in audio log. The data sheet is a good read and you might see some ideas there.

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.
