## Detailed Description

LPC subframe. (c.f. format specification)

## Member Data Documentation

## ◆ entropy_coding_method

FLAC__EntropyCodingMethod FLAC__Subframe_LPC::entropy_coding_method

The residual coding method.

## ◆ order

uint32_t FLAC__Subframe_LPC::order

The FIR order.

## ◆ qlp_coeff_precision

uint32_t FLAC__Subframe_LPC::qlp_coeff_precision

Quantized FIR filter coefficient precision in bits.

## ◆ quantization_level

int FLAC__Subframe_LPC::quantization_level

The qlp coeff shift needed.

## ◆ qlp_coeff

FLAC__int32 FLAC__Subframe_LPC::qlp_coeff[FLAC__MAX_LPC_ORDER]

FIR filter coefficients.

## ◆ warmup

FLAC__int32 FLAC__Subframe_LPC::warmup[FLAC__MAX_LPC_ORDER]

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

## ◆ residual

const FLAC__int32* FLAC__Subframe_LPC::residual

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