摘要

An interpolation device for judging a state of sounds of a frame at which an error or a loss has occurred in the audio data and carrying out the interpolation according to that state is constructed by an input unit for entering the audio data, a detection unit for detecting the error or the loss of each frame of the audio data, an estimation unit for estimating the interpolation information of the frame at which the error or the loss is detected, and an interpolation unit for interpolating the frame at which the error or the loss is detected, by using the interpolation information estimated for that frame by the estimation unit.
