Claim Text:
1. A method of generating electrode stimulation signals for electrode contacts in a cochlear implant electrode array, the method comprising: processing an input audio signal to generate a plurality of band pass channel signals each representing an associated band of audio frequencies; extracting from each channel signal channel audio information including a channel signal envelope reflecting channel signal energy; generating initial electrode stimulation pulses based on the band pass signal envelopes; applying a gating function to the initial electrode stimulation pulses based on a gating feedback signal characterizing preceding stimulation signals to produce gated electrode stimulation pulses, wherein the gated electrode stimulation pulses: providing output stimulation pulses to the electrode contacts based on the gated electrode stimulation pulses; and producing the gating feedback signal from the output stimulation pulses for the gating function.
