public class FilterAllPass extends UnitFilter
y(n) = -gain * x(n) + x(n - 1) + gain * y(n - 1)where y(n) is Output, x(n) is Input, x(n-1) is a delayed copy of the input, and y(n-1) is a delayed copy of the output. An all-pass filter will pass all frequencies with equal amplitude. But it changes the phase relationships of the partials by delaying them by an amount proportional to their wavelength,.
