摘要：The present disclosure provides a audio signal processing apparatus including,an amplitude detector configured to detect a noise start point of an audio signal
including a noise signal by comparing an amplitude value of the audio signal with athreshold value, a frequency feature calculator configured to calculate a frequencyfeature representing at least a frequency characteristic of the audio signal after the noisestart point, and a noise determiner configured to determine a leg continuously includinghigh-frequency components equal to or higher than a reference frequency in the audiosignal after the noise start point as a noise leg based on the frequency feature.
