Abstract
Aspects provide methods and sound processor for encoding stimulation signals to convey pitch perception information to a recipient. The method may comprise identifying a first stimulation site based on a selected frequency component of the sound signal that contains pitch perception information, wherein a stimulation signal is generated based on the selected frequency component; determining a second stimulation site adjacent to the first stimulation site; and determining a time delay between when the second stimulation site is independently stimulated with the stimulation signal and when the first stimulation site is independently stimulated with the stimulation signal.
