PURPOSE:To adds a reverberation sound only in a specific frequency band by removing the high frequency component of a rear part reverberation sound efficiently and increasing the density of the reverberation sound as to the reverberation addition device which provides a feeling of the extent of a music hall. CONSTITUTION:The reverberation addition device which has a 1st delay memory 1, a 1st multiplier 2 for multiplying an output signal delayed by a time T1 by a specific coefficient g1, and an adder 3 for adding the output signal to an input signal is provided with a 2nd delay memory 4 and a 2nd multiplier 5 which multiplies an output signal delayed by a time T2 by a specific coefficient g2 and adds the result by the adder 3. Further, a reverberation sound density increasing means is added and a reverberation sound emphasizing means is installed instead of the delay element 4 and multiplier 5. |
