MULTI-CHANNEL ACOUSTIC SIGNAL PROCESSING DEVICE |
摘要 |
<p>Provided is a multi-channel acoustic signal processing device by which loads of arithmetic operations are reduced. The multi-channel acoustic signal processing device (100) includes: a decorrelated signal generation unit (181), and a matrix operation unit (187) and a third arithmetic unit (186). The decorrelated signal generation unit (181) generates a decorrelated signal w' indicating a sound which includes a sound indicated by an input signal x and reverberation, by performing reverberation processing on the input signal x. The matrix operation unit (187) and the third arithmetic unit (186) generate audio signals of m channels, by performing arithmetic operation on the input signal x and the decorrelated signal w' generated by the decorrelated signal generation unit (181), using a matrix R 3 which indicates distribution of a signal intensity level and distribution of reverberation.</p> |
