Can a single-pole filter be represented using AVAudioUnitEQ? In checking AVAudioUnitEQFilterType, I found the following but I was not seeing the option. https://developer.apple.com/documentation/avfoundation/avaudiouniteqfiltertype
If so how is this possible. I like the idea of being able to utilize the built-in equalizer functions dynamically. lowPass - A simple Butterworth second-order low-pass filter. resonantLowPass - Low-pass filter with resonance support (using the bandwidth parameter). Additionally, what is the behavior if you add successive bands with the same frequency? Is the behavior an n-order filter or is this undefined? Thank you, W.
