Abstract:

There is achieved a configuration that executes sound localization processing applying a head-related transfer function (HRTF) corresponding to a user identified by a user identification, and makes an output from an output unit for each user position. The configuration includes a user identification unit that executes user identification and a user position identification process and a sound localization processing unit that executes sound localization processing using, as a processing parameter, a head-related transfer function (HRTF) specific to the user. The sound localization processing unit executes sound localization processing that treats the HRTF specific to the identified user as a processing parameter, and outputs a signal obtained by the sound localization processing to an output unit for the identified user position. In a case where the user identification unit identifies multiple users, the sound localization processing unit executes the sound localization processing using the HRTF of each of the multiple users in parallel, and outputs processed signals to an output unit for each user position.
