Abstract

A method and an apparatus for reducing noise due to a path change of an audio signal output from a device are provided. The method includes determining an input period for canceling the noise by using a time point, at which the path change is sensed, as a reference, when sensing the path change of the audio signal; low-pass filtering the audio signal in the determined input period; and interpolating a first partial signal, which is the low-pass filtered audio signal in a first predetermined period that starts from a start time point of the determined input period, and a second partial signal, which is the low-pass filtered audio signal in a second predetermined period that ends at an end time point of the determined input period, within the determined input period.
