Both of these are EXCELLENT resources. I’ve been looking into the cascading filters options that was suggested and I’ll work on implementing that, if I understand it correctly.
I will also look into the C++ library that was recommended as well.
In the process of researching what both of you said, I also found references to vDSP_biquad. https://developer.apple.com/reference/accelerate/1450838-vdsp_biquad
It sounds like a great way to go but I just have a very surface level understanding so implementation will be challenging.
Thank you both very much,
