  • Audio signal processing system
    Patent number: 9558730
    Abstract: An audio processing system includes an audio receiving module, a sound source separation module and a noise suppression module. The audio receiving module receives at least two audio signals. The sound source separation module receives a plurality of space features of the audio signals and obtains a main sound source signal separated from the audio signals based on the space features. The noise suppression module processes the main sound source signal based on an averaged amplitude value of noise in the main sound source signal so as to suppress noise in the main sound source signal. Each audio signal of the at least two audio signals includes signals from a plurality of sound sources.
