Field Summary

int	bits_per_frame Number of bits per frame after encoding
float	comb_gain Gain of enhancer comb filter
int	double_codebook Apply innovation quantization twice for higher quality (and higher bit-rate)
int	forced_pitch_gain Use the same (forced) pitch gain for all sub-frames
int	have_subframe_gain Number of bits to use as sub-frame innovation gain
CbSearch	innovation Codebook Search un-quantizer
int	lbr_pitch Set to -1 for "normal" modes, otherwise encode pitch using a global pitch and allowing a +- lbr_pitch variation (for low not-rates)
float	lpc_enh_k1 Enhancer constant
float	lpc_enh_k2 Enhancer constant
LspQuant	lsqQuant LSP quantization/unquantization function
Ltp	ltp Long-term predictor (pitch) un-quantizer
