Kira game audio library v0.8 - spatial sounds, modulators, compressor and EQ filter effects
I was looking at the filter implementation in the context of my rbj-eq filters. It looks like Kira uses a single biquad section? Is this the RBJ filter or something else? It also looks like the filter coefficients are being recomputed for every frame, which seems… a bit extreme? I may contribute something soon if I can find time.

Digital Filter Programming Advice?
If you just want good straightforward filters, biquad sections are pretty easy, run fast, and work well, especially if you have floating-point at your disposal. I have an implementation of the RBJ "equalizer filters" in Python and Rust here that you can look at for inspiration and for a fairly functional set of filter options.

How to Derive Coefficients for a 3-Pole HPF (in Rust)?
Depending on what you are trying to do you might want to take a look at my rbj-eq repo. It contains some filter generation and evaluation code. It's close to done, but still a work in progress. If nothing else, the code may give you some ideas (for better or worse).

dtmf - A no-std crate for decoding DTMF tones
If it's still not efficient enough, or doesn't have the accuracy you want, you can instead build biquad IIR filters. Those are going to be scary fast and accurate, and in this setting you can have fixed filters for a given sample rate. Here is my very, very, very work-in-progress crate that should support this: you can almost certainly do better with somebody else's.
