Description of a Speex sub-mode (wither narrowband or wideband

Member Data Documentation

int SpeexSubmode::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)

int SpeexSubmode::forced_pitch_gain

Use the same (forced) pitch gain for all sub-frames

int SpeexSubmode::have_subframe_gain

Number of bits to use as sub-frame innovation gain

int SpeexSubmode::double_codebook

Apply innovation quantization twice for higher quality (and higher bit-rate)

lsp_quant_func SpeexSubmode::lsp_quant

LSP quantization function

lsp_unquant_func SpeexSubmode::lsp_unquant

LSP unquantization function

ltp_quant_func SpeexSubmode::ltp_quant

Long-term predictor (pitch) quantizer

ltp_unquant_func SpeexSubmode::ltp_unquant

Long-term predictor (pitch) un-quantizer

const void* SpeexSubmode::ltp_params

Pitch parameters (options)

innovation_quant_func SpeexSubmode::innovation_quant

Innovation quantization

innovation_unquant_func SpeexSubmode::innovation_unquant

Innovation un-quantization

const void* SpeexSubmode::innovation_params

Innovation quantization parameters

spx_word16_t SpeexSubmode::comb_gain

Gain of enhancer comb filter

int SpeexSubmode::bits_per_frame

Number of bits per frame after encoding
