Audio signal reproducing method and reproducing apparatus

摘要

A reproducing apparatus for an audio signal includes a number of digital filters, each supplied with an audio signal, and a speaker array in a configuration in which speakers are specially arranged. Outputs of the digital filters are delivered to the speakers. Predetermined delay times are respectively set at the digital filters, so that sound waves radiated from the speakers are reflected on wall surfaces, and then arrive at a sound field to form a place having sound pressure larger than that therearound within the sound field. Outputs of a second set of digital filters are delivered to the speakers. Predetermined delay times are respectively set at the second set of digital filters so as to suppress leakage sound which directly arrives at a place having large sound pressure from the speakers among sounds formed from outputs of the digital filters.
