PURPOSE:To indicate the extent of a sound field by the size relation of one- dimensional quantities such as the combination of parameters like the level of reflected sound and the reverberation time to the direct sound and the like. CONSTITUTION:This device is provided with a digital signal processor 2 for generating plural single delay signals and cyclic type delay signals based on digital signals and synthesizing and outputting the three signals and a microcomputer 7 for adjusting the combination of three signals in the digital signal processor 2, generating plural sound field patterns, changing the level and delay time of the respective signals and letting the digital signal processor 2 switch the extending feeling of the sound field and the extending feeling of the sound field is gradually increased and decreased by an up-down operator 9. |
