  • Publication number: 20070203535
    Abstract: System and method for using Frequency-Amplitude-Modulation-Encoding (FAME) to improve the quality of sound perception for the cochlear implant users and the compress audio signals so that broadband qualities can be achieved with narrow-band transmission channels. In one embodiment, the FAME strategy extracts essential information (changes in amplitude and frequency) and is able to use a narrow-band capacity to provide broad-band (i.e. high quality) audio signals, which can be used in auditory prostheses and telecommunication.

  • Patent number: 7225027
    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.
