Liveness
Sur. 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 to get more sustaining reverberation sound, and set a shorter time to get
articulate sound.
Control range: 1.0 to 5.0 s
