Detailed Description

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

Member Data Documentation

Number of bits per frame after encoding

Gain of enhancer comb filter

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

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

Number of bits to use as sub-frame innovation gain

Innovation quantization parameters

Innovation quantization

Innovation un-quantization

Set to -1 for "normal" modes, otherwise encode pitch using a global pitch and allowing a +- lbr_pitch variation (for low not-rates)

Enhancer constant

Enhancer constant

Enhancer constant

LSP quantization function

LSP unquantization function

Pitch parameters (options)

Long-term predictor (pitch) quantizer

Long-term predictor (pitch) un-quantizer
