From what I'm told, the warmness of a large diaphragm microphone is due to the gradual transition to an omnidirectional pattern at lower frequencies. Using two omni microphones in a figure-eight pattern, with a phase inversion + delay on one mic to turn that into a cardioid microphone, and some high-pass and peak filtering, I managed to produce a microphone with a characteristic like that. The bend down at 20 kHz is the tail of the comb filter created by the phase delay.

I should probably give this simulator a better GUI. 99% of the editing is happening by changing the code at the moment.

I'm getting the hang of using transfer functions. I should probably learn how write transfer functions and how to transform them into digital filters. The only thing I could pull off with my current knowledge is to use an inverse discrete Fourier transform to turn them into filter kernels. Since these are IIR filters, they'd have to be windowed and the kernels would only approximate them.
