DIGITAL EFFECT ADJUSTMENT DEVICE AND DIGITAL ACOUSTIC DEVICE

摘要

PURPOSE:To suppress the noise to be generated at the time of changing the coefft. in the effect adjustment device of the acoustic device in which the digital signal processing is applied. CONSTITUTION:Digital integrators 47-49 are connected to the multiplication coefft. input of digital multipliers 9-11 performing the effect processing. By controlling the multiplier input by a control means 15 to smooth the multiplier, the generation of noise due to the discontinuity of an output voice signal in the effect adjustment is prevented. The digital acoustic device can be made by using the effect adjustment method.
