excite#
- class diffsptk.ExcitationGeneration(frame_period, *, voiced_region='pulse', unvoiced_region='gauss', polarity='auto', init_phase='zeros')[source]#
See this page for details.
- Parameters:
- frame_periodint >= 1
Frame period in samples, \(P\).
- voiced_region[‘pulse’, ‘sinusoidal’, ‘sawtooth’, ‘inverted-sawtooth’, ‘triangle’, ‘square’]
Value on voiced region.
- unvoiced_region[‘zeros’, ‘gauss’]
Value on unvoiced region.
- polarity[‘auto’, ‘unipolar’, ‘bipolar’]
Polarity.
- init_phase[‘zeros’, ‘random’]
Initial phase.
- forward(p)[source]#
Generate a simple excitation signal.
- Parameters:
- pTensor [shape=(…, N)]
Pitch in seconds.
- Returns:
- outTensor [shape=(…, NxP)]
Excitation signal.
Examples
>>> p = torch.tensor([2.0, 3.0]) >>> excite = diffsptk.ExcitationGeneration(3) >>> e = excite(p) >>> e tensor([1.4142, 0.0000, 1.6330, 0.0000, 0.0000, 1.7321])
