interpolate#

class diffsptk.Interpolation(period, start=0, dim=-1)[source]#

See this page for details.

Parameters:

periodint >= 1: Interpolation period, \(P\).
startint >= 0: Start point, \(S\).
dimint: Dimension along which to interpolate the tensors.

forward(x)[source]#

Interpolate signal.

Parameters:

xTensor [shape=(…, T, …)]: Signal.

Returns:

outTensor [shape=(…, TxP+S, …)]: Interpolated signal.

Examples

>>> x = diffsptk.ramp(1, 3)
>>> interpolate = diffsptk.Interpolation(3, start=1)
>>> y = interpolate(x)
>>> y
tensor([0., 1., 0., 0., 2., 0., 0., 3., 0., 0.])
