Structs

IIRDelay struct IIRDelay(T, int order): Maintain state for a filtering operation. To use an IIR filter you need an IIRDelay + one IIRCoeff.

Templates

BiquadCoeff template BiquadCoeff(T): Type which hold the biquad coefficients.
BiquadDelay template BiquadDelay(T): Undocumented in source.
