1. A system comprising:
a sound processor associated with a first ear of a recipient and configured to:
direct a cochlear implant to apply standard electrical stimulation representative of frequencies in an audio signal that are within an upper region of an audible frequency range to a cochlea of the first ear by way of a plurality of electrodes located within the cochlea of the first ear in accordance with a frequency allocation table that maps frequencies in the upper region of the audible frequency range of the recipient to the plurality of electrodes, the upper region of the audible frequency range comprising frequencies above and including a cutoff frequency that is selected based on an insertion depth of the plurality of electrodes located within the cochlea, wherein a value for the cutoff frequency is set based on a place pitch of a most apical electrode included in the plurality of electrodes and the cutoff frequency is mapped to the most apical electrode; and
direct the cochlear implant to apply electrical stimulation representative of frequencies in the audio signal that are within a lower region of the audible frequency range to the cochlea of the first ear by way of the most apical electrode included in the plurality of electrodes and one or more compensating electrodes included in the plurality of electrodes in accordance with an electrode stimulation configuration, the lower region of the audible frequency range comprising frequencies below the cutoff frequency,
wherein, in the frequency allocation table, a first electrode included in the plurality of electrodes is mapped to a first frequency corresponding to a place pitch of the first electrode and a second electrode included in the plurality of electrodes is mapped to a second frequency corresponding to a place pitch of the second electrode.
