Summary:An audio processing device includes first and second LPFs for outputting low-frequency components of a first right channel signal and a first left channel signal; a first subtracter for subtracting an output signal of the second LPF from the first right channel signal, thereby outputting a second right channel signal; a second subtracter for subtracting an output signal of the first LPF from the first left channel signal, thereby outputting a second left channel signal; a third LPF for outputting a low-frequency component of a signal obtained by addition of the first right channel signal and the first left channel signal; a first amplifier for amplifying an output signal of the third LPF; and adders for adding up the second right channel signal and an output signal of the first amplifier and to add up the second left channel signal and the output signal of the first amplifier.
