Patent ID: 8126565

Claim:
A method for use in a cochlear implant system, the method comprising: computing a frequency spectrum of a signal representative of sound in order to produce a representation of the signal that is broken down into a plurality of frequency bins that are organized into a plurality of channels such that each channel comprises a subset of the plurality of bins; determining a bin that has the most energy out of a subset of the bins corresponding to a channel included within the plurality of channels; determining whether the energy in the bin is larger than energies in other bins adjacent to the bin; if the energy in the bin is larger than energies in the adjacent bins, computing a stimulation frequency corresponding to the channel to be a frequency that corresponds to a location of a point in the middle of the bin; and if the energy in the bin is not larger than energies in the adjacent bins, computing the stimulation frequency corresponding to the channel to be a frequency that corresponds to a location of a point that lies midway between the bin and another bin having the larger energy of the adjacent bins.
