Abstract

Sub-integer resolution pitch values are estimated in making the initial pitch estimate; the sub-integer pitch values are pref-erably estimated by interpolating intermediate variables between integer values. Pitch regions are used to reduce the amount of computation required in making the initial pitch estimate. Pitch-dependent resolution is used in making the initial pitch estimate, with higher resolution being used for smaller values of pitch.
