English Digital Sound Field Parameter Descriptions REV. TIME (Reverberation Time) Function This parameter adjusts the amount of time it takes 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. Control Range 1.0 - 5.0 seconds Description Set a longer reverberation time for "dead" sources and listening room environments and a shorter time for "live" sources and listening room environments. Reverberation Source Sound Primary Reflected Sound 60 dB 60 dB Reverberation 60 dB Reverberation REV. TIME REV. TIME REV. TIME Source Sound Short Reverberation Long Reverberation Small value = 1.0 s Large value = 5.0 s REV. DELAY (Reverberation Delay) Function This parameter adjusts the time difference between the beginning of the direct sound and the beginning of the reverberation sound. Control Range 0 - 250 milliseconds Description The larger the value, the later the reverberation sound begins. A later reverberation sound makes you feel like you are in a larger acoustic environment. Source Sound (dB) Level REV. DELAY Reverberation REV TIME 60dB Time REV. LEVEL (Reverberation Level) Function This parameter adjusts the volume of the reverberation sound. Control Range 0 - 100% Description The larger the value, the stronger the reverberation becomes.
