Tables for spectrum coding. More...

#include <atrac3plus_data.h>

Data Fields
uint8_t	group_size
	number of coefficients grouped together
uint8_t	num_coeffs
	1 - map index to a single value, > 1 - map index to a vector of values
uint8_t	bits
	number of bits a single coefficient occupy
uint8_t	is_signed
	1 - values in that table are signed ones, otherwise - absolute ones
int	redirect
	if >= 0: tells which huffman table must be reused
const uint8_t *	cb
	pointer to the codebook descriptor
const uint8_t *	xlat
	pointer to the translation table or NULL if none
