Patent ID: 8868195

Claim:
A method of generating electrode stimulation signals for an implanted electrode array, the method comprising: processing an acoustic audio signal to generate a plurality of band pass signals, each of which represents an associated band of audio frequencies; for each band pass signal: i. extracting fine time structure information to determine a sequence of phase event signals for the band pass signal, ii. creating a signal limiting period after a plurality of phase event signals occurs that reaches a channel pitch rate limit characterizing saturation of pitch perception, and iii. sampling a band pass envelope at a given sampling rate, except during signal limiting periods, to determine channel amplitude values; and generating a set of electrode stimulation signals for the implanted electrode array at the sampling rates for the respective band pass signals, said set of electrode stimulation signals being stimulation pulses weighted with the respective channel amplitude values, wherein for each band pass channel, the generation of electrode stimulation signals is interrupted during each signal limiting period.
