ABSTRACT:
A method of improving sound quality of audio signals that are digitally processed includes steps of extracting amplitude and frequency modulations from one or more narrow bands of the audio signal, and filtering and compressing those modulations to produce amplitude and frequency modulated audio signals that are digitally processed to provide an acoustic signal similar to the original audio signal. The methods may be used in auditory prostheses and telecommunication systems.
