band scale factor
The methodology according to the invention can be described and iteratively expressed in an inner loop and an outer loop. An exemplary pseudo code expression for the inner loop is shown in Table C as follows:
An outer loop is used to determine the respective scale factor for each of the sub-bands. An exemplary pseudo code expression for the outer loop is shown in Table D as follows:
error_energy(sb) = error_energy(sb) + (abs( mdct_line(i))
− (x_quant(i) {circumflex over ( )}(4/3) * 2{circumflex over ( )}( −¼ *
