PROBLEM TO BE SOLVED: To prevent a low frequency level from decreasing, even when a headphone applies three-dimensional reproduction to a multi-channel stereophonic audio signal, such a AC-3. SOLUTION: The audio reproduction device is provided with conversion circuits 3F, 3B, that convert audio signals SFE-SRB among received audio signals SLF-SLFE so as to obtain a reproduction sound field in reproduction even by a headphone 7 which is, equal to a reproduction sound field obtained at loudspeaker reproduction and with adder circuits 4L, 4R that add the audio signal SLFE of the low frequency components in the received audio signals SLF-SLFE to the audio signal outputted from the conversion circuits 3F, 3B. Audio signals SL, SR outputted from the adder circuits 4L, 4R are supplied to the headphone 7. |
