void init_decod_ld8k()
int decod_ld8k(int[] parm, int voicing, float[] synth, int synth_offset, float[] A_t)
parm
- input : synthesis parameters (parm[0] = bfi)voicing
- input : voicing decision from previous framesynth
- output: synthesized speechsynth_offset
- input : synthesized speech offsetA_t
- output: two sets of A(z) coefficients length=2*MP1
