showsPrec :: Int -> Parameter a -> ShowS

show :: Parameter a -> String

showList :: [Parameter a] -> ShowS

shiftParam :: (Scalar a, Fractional a, C a) => Int -> a -> a -> Parameter a

Compute coefficients for an allpass that shifts low frequencies by approximately the shift you want. To achieve this we solve a linear least squares problem, where low frequencies are more weighted than high ones. The output is a list of coefficients for an arbitrary order allpass.
