Zusammenfassung:	An audio data processing apparatus and the like are provided in which waveform distortion generated when a virtual sound source moves relative to a speaker is processed by linear interpolation so that the speed of correction processing is achieved. This apparatus has: calculating means calculating first and second distances measured at two time points from the position of the speaker to the position of the virtual sound source; identifying means, when the first and the second distances are different from each other, identifying a distorted part in the audio data at the two time points; and correcting means correcting the audio data of the identified part by interpolation using a function.
