allnest

A nested allpass. The feedforward coefficient of the outer allpass is set from the second input, which should have an absolute value smaller than one to prevent a blowup.

If x is a delay element then the result is a Schroeder allpass. If x is a 1st order allpass (allpole) then the result is a 2nd order nested allpass.
