** AcbkGainTable085:
**
** Purpose:
** Used to calculate the error expression in pitch prediction
** optimization (also described as an adaptive codebook approach)
**
** Table Structure:
** The table is structured as 85 20-element vectors. These
** vectors are structured as precalculated values in the error
** expression for the pitch predictor. Gi is the gain value
** multiplying the signal delayed by a pitch period (+/- offset).
** In equation 41.2, Gi would be equivalent to bij.
**
** 1st 5 elements: G1 G2 G3 G4 G5 in Q14 (i.e. scaled by 16384)
** 2nd 5 elements: -G1^2 -G2^2 -G3^2 -G4^2 -G5^2
** These are scaled down by 14 bits (factor of 16384) after
** being squared.
** Next 10 elements: These are the off-diagonal elements
** -G1*G2 -G1*G3 -G2*G3 -G1*G4 -G2*G4
** -G3*G4 -G1*G5 -G2*G5 -G3*G5 -G4*G5
** These are scaled down by 14 bits (factor of 16384)

/*
** AcbkGainTable170:
**
** Purpose:
** Used to calculate the error expression in pitch prediction
** optimization (also expressed as an adaptive codebook approach)
**
** Table Structure:
** The table is structured as 170 20-element vectors. These
** vectors are structured as precalculated values in the error
** expression for the pitch
** predictor. Gi is the gain value multiplying the signal
** delayed by a pitch period (+/- offset). In equation 41.2,
** Gi would be equivalent to bij.
**
** 1st 5 elements: G1 G2 G3 G4 G5 in Q14 (i.e. scaled by 16384)
** 2nd 5 elements: -G1^2 -G2^2 -G3^2 -G4^2 -G5^2
** These are scaled down by 14 bits (factor of 16384) after
** being squared.
** Next 10 elements: These are the off-diagonal elements
** -G1*G2 -G1*G3 -G2*G3 -G1*G4 -G2*G4
** -G3*G4 -G1*G5 -G2*G5 -G3*G5 -G4*G5
** These are scaled down by 14 bits (factor of 16384)
