LIVENESS
S.LIVENESS
SB LIVENESS
Liveness. Surround and surround back liveness. Adjusts the reflectivity of the virtual walls in the
hall by changing the rate at which the early reflections decay. The early reflections of a sound
source decay much faster in a room with acoustically absorbent wall surfaces than in one which
has highly reflective surfaces. A room with acoustically absorbent surfaces is referred to as
“dead”, while a room with highly reflective surfaces is referred to as “live”. This parameter lets
you adjust the early reflection decay rate and thus the “liveness” of the room.
Control range: 0 to 10
REV.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
