PURPOSE:To reduce the scale of a DSP which performs arithmetic for generating an initial reflected sound and a reverberation sound to be added to a direct sound as to the reverberation addition device which reproduces a feeling of a spread in each music hall. CONSTITUTION:The reverberation addition device is provided with a low-pass filter 5 which is connected between an acoustic source 1 and an analog/digital converter 2 and cuts off the high frequency component of the acoustic source 1 and an addition part 6 which composes a signal of the output signals of the acoustic source 1 and digital/analog converter 4. |
