Abstract
A method for the real-time transformation of an electrical signal representative of a sound wave that includes the steps of providing an electrical signal representative of a sound wave, transforming that signal to an analytic representation, and passing said electrical signal, in parallel, through a number of bandpass filters to create a set of time domain real and imaginary band limited signals. Next, a stream of instantaneous phase angle and magnitude values for each of said set of time domain real and imaginary band limited signals is computed. Thirdly, a stream of electrical pulses or other digital representation of the phase, instantaneous frequency, and magnitude information is computed for delivery to a cochlear implant or transmission for decoding and synthesis of the original sound.
