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.
