I have searched high and low trying to find a way to have (for example) 3 LEDs, that light up according to different frequency ranges.
The intended result would be a box with audio input, LEDs that react to different ranges, and pots to select the ranges.
So basically you could have 1 LED for bass, 1 for mid, and 1 for treble.
The frequency range for each LED is selected with a pot/knob.
Perhaps there should be 2 pots for each LED, the 1st pot sets the min and the 2nd pot sets the max frequency (each LED has it's own bandpass)
There is a lot of information about RC filters out there but none seem to go in this direction. Any better ways to implement? I don't know where to start. I just want to get ONE LED going, even without a pot. Any help is appreciated.
