REVERBERATION ADDING APPARATUS

摘要

A memory device 10 sequentially stores amplitude data representing an amplitude value of an input musical tone according to clock pulses having a predetermined period, delay time information is generated (20) to determine a delay time of a reverberation tone to be generated, a first address information is generated (30) for designating a first area in said memory device to store amplitude input data which is the amplitude data of said musical tone at a present time and a second address information is generated (30) for designating a second area in said memory device to read out an amplitude output data which is equal to the amplitude input data stored in the memory device at a time preceding the present time by a time interval designated by the delay time information. Level control means 501 controls the level of the amplitude output data and converting means 502 converts the level-controlled data to a reverberation tone of the input musical tone.
