Abstract:
A processor combines a first predicted signal generated based on an audio signal in an interval preceding a noise detection interval, and a second predicted signal generated based on an audio signal in an interval succeeding the noise detection interval, based on the ratio between the periodicity of the audio signal in the interval preceding the noise detection interval, and the periodicity of the audio signal in the interval succeeding the noise detection interval. The processor replaces the audio signal in the noise detection interval with the combined signal.
