Best way to implement a dbu meter using 6 LED's

Hi All,

 

I am trying to implement a dbu meter and have 6 LED's setup to do so... would like to do -24, -18, -12, -6, -3 and 0db light up accordingly. I have tried using the RMS limiter to do this and I can get the LED to come on but the calibration is way off.. 0db coming in has to have -5db in the RMS limiter to make it work.

 

I put in a signal detect bar in to measure the level coming in and if I send -10db it is showing -10db so all that seems to be working correctly.

 

I have also put in dc blocking filter in to remedy any issues caused by things along those lines.

 

Open to all suggestions.

 

Thanks,,

 

Mick
