Audio control apparatus and method

Abstract

According to an embodiment, an audio control apparatus includes a calculation unit and a determination unit. The calculation unit is configured to calculate an interaural cross-correlation function of a binaural recording signal at regular time intervals. The determination unit is configured to determine that a signal zone in which peak times of interaural cross-correlation functions are consecutively included in one of a plurality of time ranges determined in advance is a localized-sound zone in which a sound-image is localized, each of the peak times being a time at which a corresponding cross-correlation function takes a maximum value.
