摘要： An audio signal processing device includes an audio signal processing unit which performs signal processing on an audio signal, a sound volume setting receiving unit which receives a sound volume set value, and a sound volume measuring unit which measures a sound volume at a listening position. The audio signal processing unit performs a loudness correction which increases a level of the audio signal in a prescribed frequency range as the sound volume set value decreases. The sound volume measuring unit measures sound volumes corresponding to plural respective sound volume set values at the listening position. The audio signal processing unit sets a level adjustment amount to be used in performing the loudness correction based on the sound volume set value received by the sound volume setting receiving unit and the measurement sound volumes of the sound volume measuring unit.
