where O (i) = 1 means the shift value of each shifted bin is 1. The he distortion is calculated in two parts: (a) The former term in (4) is the shifting distortion for non-peak bins, denoted as D, caused by those bins’ shifting as an entirety in the range [P1 + 1; Z1 − 1]; (b) The other one is the embedding distortion for peak bin P1, denoted as D , where means peak bins P1 is only once (single) utilized and half of P1 is shifted to its adjacent vacant value by 1.
