I've done more testing on to explore what the root cause might be and I was able to recreate the pain/tinnitus at a very low volume by cranking the sympathetic resonance and impedance up simultaneously.
It just felt like something was causing pain in my ears when I did this, as if I was listening to a very loud sound that I is outside of my normal range of hearing.
By doing this, my ears started ringing very quickly almost instantly, and it was also physically painful to listen to as if a physically loud sound was in my ear that I couldn't hear.
Not sure exactly what's going on, but this particular test really made the problem apparent enough that I'm now hesitant to continue using the program at all because I was able to generate pain at a volume that is not only apparently safe, but actually quite quiet.
Sorry, I haven't read the whole thread and this has probably been discussed, but can't you use an EQ to cut off those "out of normal range" frequencies you think you are getting?
Not if I don't know where they are coming from.
I've found that cutting high frequencies is actually a lot less helpful than I initially thought.
Hence, because the issue at hand is clearly acoustically complex/hard to tease out the root cause, I'm mostly posting this so that Modartts audio engineers can troubleshoot.
This is a topic that covers physics, human biology and signal processing. There are a lot of potentially very counterintuitive places in that chain of things that it could be, and honestly I'd mainly like to leave it up to the engineers at Modartt.
For instance, the issue could be in the way pianoteq actually does its conversion, and such frequencies might bypass their internal filters.
Fourier analysis involves infinite sums of series of sine waves, though later terms start mattering less in the series. Combine that with digital conversion where you're taking discrete 0s and 1s and turning it into a continuous set of waves and you have a recipe for a mystery.
There's a lot of place for errors and tricky counterintuitive possible sources of this problem that perhaps no one here including myself has even considered... that's just the way these things go speaking from my experience working in labs on various physics related subjects.
