Publication number: 20230224666Abstract: 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.Type: ApplicationFiled: March 15, 2023Publication date: July 13, 2023Inventors: Shuji MIYASAKA, Kazutaka ABE, Yasunori NARUSE
