AUDIO-SIGNAL PROCESSING DEVICE, AND AUDIO-SIGNAL PROCESSING METHOD

摘要

This audio-signal processing device is provided with: an audio-signal processing unit which performs signal processing on an audio signal; a volume-setting reception unit which receives volume-setting values; and a volume measurement unit which measures volumes at listening positions. The audio-signal processing unit performs loudness correction in which the levels of prescribed frequency bands of the audio signal are increased in accordance with reductions in the volume-setting values. The volume measurement unit respectively measures the volumes at the listening positions, said volumes corresponding to the plurality of volume-setting values. The audio-signal processing unit sets the level-adjustment amounts during the loudness correction in accordance with the volume-setting values received by the volume-setting reception unit, and the measured volumes measured by the volume measurement unit.
