Search for a comparable feature to the "Intelligibility Meter" in iZotope's Insight 2

I find the principle behind the “Intelligibility Meter” very handy. So I was wondering if there are any comparable plug-ins or functions?

I am looking for a way to measure individual audio channels or a sum of audio channels relative to another track/bus. Insight displays the difference in loudness (phon). It would be great if I had the choice to select other measurement units as well (not just units for loudness).

Does anyone know of such a tool/plug-in?

After I had time over Christmas, I have looked around a bit. By chance I came across the plug-in GainMatch from “LetiMix”. A great little tool! Exactly what I was looking for.

Highly recommended. :+1:
