Method Detail

init_exc_err

void init_exc_err()

test_err

int test_err(int t0,
             int t0_frac)

Computes the accumulated potential error in the adaptive codebook contribution

Parameters:

t0 - (i) integer part of pitch delay

t0_frac - (i) fractional part of pitch delay

Returns:

flag set to 1 if taming is necessary

update_exc_err

void update_exc_err(float gain_pit,
                    int t0)

Maintains the memory used to compute the error function due to an adaptive codebook mismatch between encoder and decoder

Parameters:

gain_pit - (i) pitch gain

t0 - (i) integer part of pitch delay
