The present invention relates to an audio apparatus that enables all listeners at seats within a vehicle compartment to obtain the same effect of sound spread feeling and sound image rise feeling. A front speaker FSP and a headlining speaker HSP are disposed separately in up and down directions relative to the listeners within the vehicle compartment. The apparatus delays the output time of sound from a speaker that is located at a shorter distance to the listeners than distances from other speakers to these listeners. When the listeners listen to sounds from the speakers FSP and HSP, the delay time is set based on a largest difference between the arrival time of the sound from the speaker FSP to each listener and the arrival time of the sound from the speaker HSP to the same listener, among all arrival-time differences. When the delay time is set longer, the listeners can secure a sound image forward-location feeling.
