Sound fi«ld parameter

REU.TIME

Reverberation time. Adjusts the amount of time taken for the dense, subsequent reverberation

sound to decay by 60 dB at 1 kHz. This changes the apparent size of the acoustic environment

over an extremely wide range. Set a longer reverberation time for “dead” sources and listening

room environments, and a shorter time for “live” sources and listening room environments.

Control range; 1.0 to 5.0 s

Reverberation

Reverberation

Small value = 1.0 s

Large value = 5.0 s

REU.DELHV

Reverberation delay. Adjusts the time difference between the beginning of the direct sound and

the beginning of the reverberation sound. The larger the value, the later the reverberation sound

begins. A later reverberation sound makes you feel as if you are in a larger acoustic environment.

Control range; 0 to 250 ms

REU.LEUEL

Reverberation level. Adjusts the volume of the reverberation sound. The larger the value, the
stronger the reverberation becomes.

Control range; 0 to 100%
