Acoustic signal processing unit |
摘要 |
An acoustic signal processing unit is provided which enables high-speed processing with reducing the amount of calculations. It includes a bandwidth division section for dividing a bandwidth of an acoustic transfer function including information about shapes of external ears and head of a listener; a high frequency component processing section for simplifying characteristics of the high frequency components obtained by the division through the bandwidth division section; and a signal synthesizing section for synthesizing components excluding the high frequency components obtained by the division through the bandwidth division section with the high frequency components passing through processing by the high frequency component processing section.
