Audio content providing device, control method, and program

Abstract

This audio content provision device (2000) acquires user position information (80) that indicates a user position (30). The audio content provision device (2000) sets a sound image localization position (50) on the basis of the user position (30) and a reference position (40) when a user (20) is present within a target region (70). The distance between the user position (30) and the sound image localization position (50) is shorter than the distance between the user position (30) and the reference position (40). The audio content provision device (2000) outputs audio content (10) such that a sound image is localized at the sound image localization position (50).
