摘要

Disclosed is an audio data processing device and the like wherein correction processing is accelerated by means of linear interpolation of waveform distortion arising when a virtual sound source moves away from a speaker. The device has: a calculation means that calculates a first distance and a second distance from the position of the speaker to the position of the virtual sound source respectively at almost simultaneous points in time; a determination means that, when the first distance and the second distance differ, determines the distorted portion in the audio data at the earlier and later points in time; and a correction means that corrects the determined portion of the audio data by means of interpolation using a function.
