Claim 16:
17. A cochlear implant system comprising:
receiver configured to receive an acoustical signal and transmit an audio signal based on the acoustical signal,
a processor configured to receive and divide the audio signal into a plurality of band limited audio signals and to generate a plurality of stimulation pulses based on sampling of the plurality of band limited audio signals, and wherein each of the plurality of band limited audio signals is sampled with a temporal onset, and one or more audio components are determined for each of the sampled plurality of stimulation pulses, and
an electrode array including a plurality of electrodes,
wherein the processor is configured to switch between using a fixed stimulation frame onset or a variable stimulation frame onset for frame coding the plurality of stimulation pulses into one or more stimulation frames, wherein the processor is configured to switch between the fixed stimulation frame onset and the variable stimulation frame onset based on the one or more audio components, and wherein the electrode array is configured to stimulate auditory nerves of a user of the cochlear implant system based on the frame coded plurality of stimulation pulses, and
wherein the processor is configured to provide a first frame coding scheme and a second frame coding scheme for frame coding the plurality of stimulation pulses into the one or more stimulation frames for the fixed stimulation frame onset and the variable stimulation frame onset, respectively, and where the first frame coding scheme is different from the second frame coding scheme.
