interpolate

class diffsptk.Interpolation(period, start=0)

See this page for details.

Parameters:

periodint >= 1 [scalar]

Interpolation period, \(P\).

startint >= 0 [scalar]

Start point, \(S\).

forward(x, dim=-1)

Interpolate signal.

Parameters:

xTensor [shape=(…, T, …)]

Signal.

dimint [scalar]

Dimension along which to interpolate the tensors.

Returns:

yTensor [shape=(…, TxP+S, …)]

Interpolated signal.

Examples

>>> x = torch.arange(1, 4)
>>> interpolate = diffsptk.Interpolation(3, start=1)
>>> y = interpolate(x)
>>> y
tensor([0, 1, 0, 0, 2, 0, 0, 3, 0, 0])
