An auditory stimulation signal processing device includes a plurality of signal inputs adapted to receive a plurality of frequency bin signals； a signal selector adapted to select a selected frequency bin signal from the plurality of frequency bin signals； a parameter modifier adapted to vary at least one stimulation signal generation parameter used for generating an electrode stimulation signal and affecting a shape of a basic stimulation pulse； and an electrode stimulation signal generator adapted to generate the electrode stimulation signal for application to an electrode of a neural auditory prosthesis, the electrode corresponding to a frequency of the selected frequency bin signal. A corresponding method and a computer readable digital storage medium are also disclosed.
