Audio enhancement system installed in e.g. mobile device for suppressing background noise and adjusting echo cancellation, has noise reduction unit that provides reduction of audio disturbance in signal supplied to microphone

摘要

The audio enhancement system (115) has display unit (130) that displays waveform subjected to audio disturbance, corresponding to signal supplied to microphone. A noise reduction unit (116) is adapted to provide reduction of audio disturbance in the signal supplied to microphone. The reduced audio disturbance is indicated by waveform in real time.
