The anti-spam seemed to eat my first version of this comment? Friendly fire! Friendly fire!
==================
Not exactly an answer to your question, but we run an Apex 220 (inexpensive linear measurement omni mic) into a spare channel on the dLive surface, send a tieline out via Dante to our FOH Mac Mini and run that and the PAFL bus into Aurchitect’s Spectre. This lets us see what’s happening in the room, vs what’s coming out of the board. It’s not a dual transfer function FFT like SMAART, but it’s still pretty useful.
(If you don’t have Dante, you could use an audio interface like a Sapphire 2i2 right into your Mac or PC).
The spectogram view is very handy for finding troublesome rings since intensity, frequency and time are all shown.
You don’t even need the mic if you just use the PAFL bus. So for the price of a basic interface and $80 for Spectre, you could be up and running pretty easy.
For example, PAFL a flute and you can see the exact frequencies of the notes (including harmonics) they’re playing over time.
