trying to get the SMD LEDs on one side of a pcboard with the other side to mount the LM3916"s and resistor arrays.
No that would be a double sided board with feedthroughs.This would be a one sided board. LEDs on bottom side.

perhaps I used wrong terminology.
suggestions for calibrating the led displays/filters
Take a variable frequency sine-wave oscillator and sweep its frequency with a sawtooth waveform. It feeds the input of an amplifier. The output of the amplifier feeds the vertical input of an oscilloscope.
You can see the frequency response of the amplifier on the screen of the oscilloscope when the same sawtooth waveform is driving its horizontal amplifier.
LOG SWEEP SINE TONE??
going to have to research and how to produce.
It's also quite amusing to read the lack of knowledge i had before lmao.
