Abstract
A reverberation-imparting device includes a delay line for storing a signal to which a reverberation effect is to be imparted. The delay line has at least one reading location determining timing for reading out the signal stored therein. An address generator generates basic reading address values for determining the at least one reading location. The basic reading address values are modulated by at least two different random numbers generated by a random number generator to determine reading address values. At least two signals read from the delay line are cross-faded, based on the modulated reading address values, such that the at least two signals are alternately intensified and attenuated with a predetermined phase difference. In a preferred application of the invention, the cross-faded at least two signals are output and delivered to a suitable reverberation-imparting device.
