Claims

[Claims for Utility Model Registration] (1) Early reflection adding means consisting of a delay means that obtains a plurality of delay time outputs for an input signal, and reverberation consisting of a plurality of delay means whose inputs are the outputs of the early reflection adding means. A reverberation adding device comprising: an adding means; a sound volume adjusting means for adjusting the output volumes of the early reflection adding means and the reverberation adding means; and an adding means for adding the outputs of the sound volume adjusting means. (2) The reverberation adding means includes an input side reverberation adding means consisting of a plurality of delay means that commonly receives the output of the early reflection adding means, and two sets of input side reverberation adding means having the output of the input side reverberation adding means as a common input. A utility model according to claim 1, comprising a delay means and an output means for independently outputting the outputs of the two sets of delay means, and a stereo output is obtained from the output means. Reverberation adding device.
