Abstract
A system and method of signal processing for a hearing implant. The hearing implant includes at least one electrode, each electrode associated with a channel specific sampling sequence. An acoustic audio signal is processed to generate for each electrode a band pass signal representing an associated band of audio frequency. For each electrode, a sequence signal is determined as a function of the electrode's associated band pass signal and channel specific sampling sequence. An envelope of each band pass signal is determined. The envelope of each band pass signal is filtered to reduce modulations resulting from unresolved harmonics, creating for each electrode an associated filtered envelope signal. Each electrode's sequence signal is weighted based, at least in part, on the electrode's associated filtered envelope signal.
