C++ (Cpp) LPC_Frame_to_Polynomial Examples

Example #1

File: LPC_and_Formant.cpp Project: georgiee/lip-sync-lpc

void LPC_Frame_into_Formant_Frame (LPC_Frame me, Formant_Frame thee, double samplingPeriod, double margin) {
	thy intensity = my gain;
	if (my nCoefficients == 0) {
		return;
	}

	autoPolynomial p = LPC_Frame_to_Polynomial (me);
	autoRoots r = Polynomial_to_Roots (p.peek());
	Roots_fixIntoUnitCircle (r.peek());
	Roots_into_Formant_Frame (r.peek(), thee, 1 / samplingPeriod, margin);
}

Example #2

File: LPC_and_Polynomial.cpp Project: READSEARCH/praat

	try {
		long iFrame = Sampled_xToIndex (me, time);

		if (iFrame < 1 || iFrame > my nx) {
			Melder_throw (U"invalid frame number.");
		}
		autoPolynomial thee = LPC_Frame_to_Polynomial (&my d_frames[iFrame]);
		return thee;
	} catch (MelderError) {
		Melder_throw (me, U":no Polynomial created.");
	}
