SOUND FIELD PROGRAMS
Sound field parameter
REV.TIME
REV.DELAY
60
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
60 dB
REV.TIME
Sound source
Short
reverberation
Small value = 1.0 s
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
