Claim 14:
15. The apparatus according to claim 14, wherein the programming instructions for execution by the at least one processor, when executed by the at least one processor cause the encoding apparatus further to:
determine a closed-loop pitch period integer part loc_T0 of the first secondary channel signal and a closed-loop pitch period fractional part loc_frac_prim of the first secondary channel signal based on the estimated pitch period value; and
calculate the closed-loop pitch period reference value f_pitch_prim of the first secondary channel signal in the following manner:

f_pitch_prim=loc_T0+loc_frac_prim/N; wherein

N represents the quantity of subframes of the first secondary channel signal.
