data T t y
interpolation as needed for resampling
cyclicPad :: C t => (T t y -> t -> T y -> a) -> T t y -> t -> T y -> a
Only for finite input signals.
extrapolationPad :: C t => (T t y -> t -> T y -> a) -> T t y -> t -> T y -> a
The extrapolation may miss some of the first and some of the last points
multiRelative :: C t => T t y -> t -> T y -> T t -> T y
All values of frequency control must be non-negative.
multiRelativeExtrapolationPad :: C t => T t y -> t -> T t -> T y -> T y
The extrapolation may miss some of the first and some of the last points
Consider the signal to be piecewise constant, where the leading value is used for filling the interval [0,1).
cubic :: (C t, C t y) => T t y
Consider the signal to be piecewise cubic, with smooth connections at the nodes. It uses a cubic curve which has node values x0 at 0 and x1 at 1 and derivatives (x1-xm1)2 and (x2-x0)2, respectively. You can see how it works if you evaluate the expression for t=0 and t=1 as well as the derivative at these points.
with this wrapper you can use the collection of interpolating functions from Donadio's DSP library
