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 tim e for “live”

sources and listening room environments.

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.

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.
