Detailed Description

Butterworth IIR (2nd order recursive) filter. This operates upon a buffer of frames of amplitude samples by applying the following equation y(n) = a0*x(n) + a1*x(n-1) + a2*x(n-2) - b1*y(n-1) - b2*y(n-2) where x is an amplitude sample. It has constructors that can calculate the coefficients from a given cutoff frequency.
