delay#

class diffsptk.Delay(start, keeplen=False, dim=-1)[source]#

See this page for details.

Parameters:

startint: Start point, \(S\). If negative, advance signal.
keeplenbool: If True, output has the same length of input.
dimint: Dimension along which to shift the tensors.

forward(x)[source]#

Delay signal.

Parameters:

xTensor [shape=(…, T, …)]: Signal.

Returns:

outTensor [shape=(…, T-S, …)] or [shape=(…, T, …)]: Delayed signal.

Examples

>>> x = diffsptk.ramp(1, 3)
>>> delay = diffsptk.Delay(2)
>>> y = delay(x)
>>> y
tensor([0., 0., 1., 2., 3.])
