PROBLEM TO BE SOLVED: To provide an audio signal supply apparatus with a simple configuration for enabling a user to simply and intuitively set directivity of a speaker array. SOLUTION: A delay information generation part 120 determines a delay time curve based on a difference (both ends time difference) between audio signals input by an input part 130 and supplied to a speaker unit 21-1 and a speaker unit 21-6 and a curvature of the delay time curve so as to generate delay time information. The delay time curve is a curve wherein an x-axis shows a distance of respective speaker units from the speaker unit 21-1, and a y-axis is drawn on Cartesian coordinates showing the difference between the delay time of the audio signal supplied to the speaker unit 21-1 and the delay time of the audio signal supplied to the respective speaker units.
