<p>In a rear reverberation creation device 22, convolution computations are performed on direct sound or initial reflected sound contained in the sound signals of the respective channels of multi channel surround sound signals. Rear reverberation groups that have flat frequency characteristics and have non-uniform delay time intervals, and that have different delay time intervals for the respective channels while having the same envelope characteristics for the respective channels are created and output for the respective channels.</p> |
