out
- intermediate polynomial, Q20.cLSF
- vector of interleaved 2*cos(LSFs), Q20.cLSF_offset
- offset of valid data.dd
- polynomial order (= 1/2 * filter order).static void SKP_Silk_NLSF2A(short[] a, int[] NLSF, int d)
a
- monic whitening filter coefficients in Q12, [d].NLSF
- normalized line spectral frequencies in Q15, [d].d
- filter order (should be even).
