PURPOSE:To obtain a clear and beautiful reverberation sound by forming a reverberation equipment unit with a reverberation addition unit means, a reverberation generating means and a sound image localization means and installing plural reverberation equipment units side by side. CONSTITUTION:A sound image localization means FD0 calculates sound image localization to add a sound image to a sound source and reverberation sound generating means RV11-RV14 obtain a reverberation sound signal data representing the reverberation sound in each direction caused in a music hall. The reverberation sound signal data is inputted to sound image localization means FD1-FD8 to calculate the sound image localization corresponding to the direction of the reverberation sound and the result is outputted to adder means A11, A12. The reverberation sound generating means RV11-RV14 consist of single or combination of plural reverberation addition units and obtain the reverberation sound by calculation. The reverberation sound effect is added to an input sound signal data and the sound image is localized to the reverberation sound in this way, then the clear and beautiful reverberation sound is obtained. |
