I've have not been able to find a source for the derivations of the equations for calculating the filter coefficients for biquad filters. I'd like to include the derivations, so if anyone knows a nice…

For odd filter orders a pair of real poles get added rather than a single pole, don't think that is right. In Butterworth::prototypeAnalogLowPass(int filterOrder) rather than
` for(uint32_t k = …

Hi!
I have recently been trying to use IIR filter to do some feedback experiment, but found out that it adds substantial digital noise to the feedback signal.
As a comparison, when the signal i…

Chatting with @JackyLigon on slack this morning and he suggested a new filter type, the Formant filter.
I said
>And Formant filter - you mean just ‘3 poles medium-tight set of bandpass in one f…

Hi,
Thanks for making this library available.
I'm just starting to try it out. My goal is to use it to create bandpass filters.
I noticed however, that there is only one freq parameter in the…

### Description
The biquad coefficients generated from the (somewhat undocumented) `control_sgtl5000.cpp:calcBiquad()` function differ from those generated and required by the `filter_biquad.cpp` f…

Hello Christian,
thank you for sharing this project. I am currently testing IIRNet with some magnitude responses I have and trying to compare the results with an optimisation based approach. Unfor…

A bug introduced with rustc 1.12.0 with MIR enabled.
This was originally reported imprecisely as #40044
If anywhere in the code a vector is either resize() or extend_from_slice(), any algorithms …
