Abstract: An audio communication device includes: a sound position determiner that determines sound localization positions for N audio signals in a virtual space having first and second walls; N sound localizers each performing sound localization processing to localize sound in the sound localization position determined by the sound position determiner, and outputting localized sound signals; an adder that sums the N localized sound signals, and outputs a summed localized sound signal. Each sound localizer performs the processing using: a first head-related transfer function (HRTF) assuming that a sound wave emitted from the sound localization position of the sound localizer determined by the sound position determiner directly reaches each ear of a hearer virtually present at the hearer position; and a second HRTF assuming that the sound wave emitted from the sound localization position reaches each ear of the hearer after being reflected by closer one of the first and second walls.

Abstract: A signal processor that performs crosstalk cancellation on an audio signal that is input, in a distorted acoustic space where two speakers are placed, the two speakers including an X-side speaker and a Y-side speaker, where X denotes one of left and right, and Y denotes the other of left and right. The signal processor causes the Y-side speaker to output a sound of the audio signal and causes the X-side speaker to output a sound of a signal obtained by processing the audio signal using transfer function GCY, where a transfer function between the Y-side speaker and the Y-side ear is defined as GYY, a transfer function between the X-side speaker and the Y-side ear is defined as GXY, and a transfer function obtained by dividing the transfer function GYY by the transfer function GXY is defined as GCY.
