Detailed Description

template<class Numeric, class Coeff = float_type>
class SPUC::allpass_1< Numeric, Coeff >

Template class for 1st order allpass filter with programmble gain and delay.

Template class for 1st-order Allpass filter. The filter is a "first-order" Allpass section of the form G(z,n) = (a*z^n + 1)/(z^n+a) The delay n can be specified
