Abstract
In a reverberation effect imparting apparatus, sampled data of an input signal is written into a RAM 23 and the data is read out after an elapse of a predetermined time period, thereby imparting a reverberation effect. A storage area of the RAM 23 is divided into an area 1 for storing waveform data and an area 2 for imparting a reverberation effect. During evaluation, the waveform data is sequentially read out from the area 1 by using an absolute address, and sampled data of the waveform data is written into and read out from the area 2 by using a relative address, thereby imparting a reverberation effect.
