PROBLEM TO BE SOLVED: To combine richness of an input signal with an output signal by selectively connecting an output of an addition filter based on an addition plan, connecting a total sum output element with a beforehand selected combination between an early stage reflection tap output and an input signal time synchronous data element and generating a pseudo reverberant signal. SOLUTION: An input signal processor 50 supplies a processed input signal DS' to a post processor 300. A pre-processor 100 supplies an output PPO, and the PPO is supplied to a diffusion field processor 200. Further, the pre-processor 100 supplies the output EROm.v from plural initial or early stage reflection taps, and the EROm.v is inputted to the post processor 300. The diffusion field processor 200 supplies the output DFPO, and the DFPO is supplied to the post processor 300. The post processor 300 outputs an audible output signal PRO containing plural output channels. The audible output signal PRO is provided with a pseudo reverberant characteristic given to itself. |
