Abstract

A method for processing sound signals to generate electrical stimuli for an auditory prosthesis electrode array including a plurality of electrodes, the method including: deriving (10) one or more filtered representations (FIGS. 3 and 4) of an incoming audio signal; and, generating (11) a series of spikes from each filtered signal representation to directly control electrode stimulation. Each spike has a temporal position based upon an instant at which the filtered signal representation crosses a predetermined threshold (ÿ;0).
