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 20):
The system of  claim 19  further operable to estimate spectral gain for noise reduction using SRR and spectral gain floor to reduce distortion in the enhanced output signal, and apply noise-reduction spectral gain to reduce background noise, and wherein the STPSD is estimated by estimating in real time the STPSD of noise.
