Abstract: An audio data processing apparatus and the like are provided in which waveform distortion generated when a virtual sound source moves is resolved so that noise caused by waveform distortion is reduced remarkably. The present invention includes: a step of calculating distances measured at different time points between the position of the virtual sound source and a speaker; a step of, when these distances are different from each other, judging whether the virtual sound source is departing or approaching relative to the speaker; and a step of identifying and correcting the part of waveform distortion depending on departing or approaching.

Abstract: Positive and negative two terminals of each of a plurality of main speakers constituting an array speaker are connected to each of amplifiers. Then, the main speakers are bridge-driven. Sub-speakers interpolating the main speakers are arranged respectively between the main speakers. Then, the positive and negative terminals of each of the sub-speakers are connected respectively to the terminals of the same polarities of the adjacent two of the main speakers. One sub-speaker receives an average value of the signals provided to the adjacent two main speakers, so that the one sub-speaker interpolates the wavefronts emitted from the adjacent two main speakers.

Abstract: 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.
