static float | fixed_gain_smooth (AMRContext *p, const float *lsf, const float *lsf_avg, const enum Mode mode) |
fixed gain smoothing Note that where the spec specifies the "spectrum in the q domain" in section 6.1.4, in fact frequencies should be used. | |
static void | decode_gains (AMRContext *p, const AMRNBSubframe *amr_subframe, const enum Mode mode, const int subframe, float *fixed_gain_factor) |
Decode pitch gain and fixed gain factor (part of section 6.1.3). |
