Abstract:
Systems and methods for processing an audio signal include an audio input operable to receive an input signal comprising a time-domain, single-channel audio signal, a subband analysis block operable to transform the input signal to a frequency domain input signal comprising a plurality of k-spaced under-sampled subband signals, a reverberation reduction block operable to reduce reverberation effect, including late reverberation, in the plurality of k-spaced under-sampled subband signals, a noise reduction block operable to reduce background noise from the plurality of k-spaced under-sampled subband signals, and a subband synthesis block operable to transform the subband signals to the time-domain, thereby producing an enhanced output signal.

Claim (Index 1):
A method for processing an audio signal comprising:\n receiving an input signal comprising a time-domain, single-channel audio signal; transforming the input signal to a frequency domain input signal comprising a plurality of k-spaced under-sampled subband signals; reducing reverberation effect, including late reverberation, in the plurality of k-spaced under-sampled subband signals; reducing background noise from the plurality of k-spaced under-sampled subband signals; and transforming the subband signals to the time-domain, thereby producing an enhanced output signal.
