RA144Context Struct Reference

#include <ra144.h>

Data Fields

AVCodecContext * avctx

AudioDSPContext adsp

LPCContext lpc_ctx

AudioFrameQueue afq

int last_frame

unsigned int old_energy

previous frame energy

unsigned int lpc_tables [2][10]

unsigned int * lpc_coef [2]

LPC coefficients: lpc_coef[0] is the coefficients of the current frame and lpc_coef[1] of the previous one.

unsigned int lpc_refl_rms [2]

int16_t curr_block [NBLOCKS *BLOCKSIZE]

int16_t curr_sblock [50]

The current subblock padded by the last 10 values of the previous one.

int16_t adapt_cb [146+2]

Adaptive codebook, its size is two units bigger to avoid a buffer overflow.

int16_t buffer_a [FFALIGN(BLOCKSIZE, 16)]
