## Member Data Documentation

FLAC__EntropyCodingMethod FLAC__Subframe_LPC::entropy_coding_method

The residual coding method.

unsigned FLAC__Subframe_LPC::order

The FIR order.

unsigned FLAC__Subframe_LPC::qlp_coeff_precision

Quantized FIR filter coefficient precision in bits.

int FLAC__Subframe_LPC::quantization_level

The qlp coeff shift needed.

FLAC__int32 FLAC__Subframe_LPC::qlp_coeff[FLAC__MAX_LPC_ORDER]

FIR filter coefficients.

FLAC__int32 FLAC__Subframe_LPC::warmup[FLAC__MAX_LPC_ORDER]

Warmup samples to prime the predictor, length == order.

const FLAC__int32* FLAC__Subframe_LPC::residual

The residual signal, length == (blocksize minus order) samples.
