  • Digital audio processing system and method
    Patent number: 9154881
    Abstract: Systems and method for audio processing are disclosed. Left and right channels of an audio data stream are combined to derive sum and difference signals. A time domain to frequency domain converter is provided for converting the sum and difference signals to the frequency domain. a first processing unit is provided for deriving a frequency domain noise signal based at least partly on the frequency domain difference signal. A second processing unit is provided for processing the frequency domain sum signal using the noise signal thereby to reduce noise artifacts in the sum signal. A frequency domain to time domain converter is provided for converting at least the processed frequency domain sum signal to the time domain.
