Latest Patents
One of Kabal's latest patents is a method and apparatus for extending the bandwidth of a speech signal. This innovation includes a bandwidth extension module and an associated method suitable for artificially extending the bandwidth of a lowband speech signal. The module comprises a band-pass filter that produces a band-pass signal from the lowband speech signal. It also features at least one carrier frequency modulator, which pitch-synchronously modulates the band-pass signal about a respective carrier frequency. Collectively, these modulators produce a highband speech signal component. Additionally, a synthesis filter determines a highband speech signal based on this component, while a summation module combines the lowband and highband speech signals to obtain a bandwidth-extended speech signal.
