What is the default IIRFilter?

When I call IIRCoefficients::makeLowPass, what is the filter type produced by those coefficients? Butterworth? Chebyshev? I don’t see it in the documentation but I’d really like to know.

Hello! Depending on the arguments you provided, it can be a Butterworth (with no resonance provided) or just a regular biquad low-pass filter with variable resonance and cutoff frequency.
