Abstract
A reverberation imparting device comprises a delay memory storing input signal data at a predetermined sampling period and producing a delay signal corresponding to time interval between writing of the input signal data and reading thereof, a plurality of address each adding delay signals read out from the delay memory, and an output section for delivering out an output of each of the adders as a reverberation signal. The delay signals are divided into groups and processed on the group basis. This simplifies the construction of the device and facilitates setting and changing of the reverberation characteristics.
