Abstract: Among other things, enhancing spectral contrast for a cochlear implant listener includes detecting a time domain signal. A first transformation is applied to the detected time domain signal to convert the time domain signal to a frequency domain signal.

A sensitivity of the cochlear implant listener to detect modulation of each component is obtained.
