ACOUSTIC SIGNAL REPRODUCING DEVICE AND ACOUSTIC SIGNAL PREPARATION DEVICE

摘要

PROBLEM TO BE SOLVED: To control a volume while maintaining recommended loudness specified for each acoustic space layer adaptively to a multichannel acoustic system including a plurality of acoustic space layers.SOLUTION: An acoustic signal reproducing device is a reproducing device for a multichannel acoustic signal including a plurality of acoustic space layers and comprises a volume control section for controlling a volume of each acoustic space layer on the basis of recommended loudness of each acoustic space layer described in meta data included in the multichannel acoustic signal.
