Sound field parameter	Features
Liveness	Liveness. Surround and surround back liveness. Adjusts the reflectivity of the virtual walls in the hall by changing the rate
Sur. Liveness	at which the early reflections decay. The early reflections of a sound source decay much faster in a room with acoustically
SB. Liveness	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.

	Small value = 1.0 s				Large value = 5.0 s
Rev. Delay	Reverberation delay. Adjusts the time difference between the beginning of the direct sound and the beginning of the
	reverberation sound. The larger the value, the later the reverberation sound begins. A later reverberation sound makes you
	feel as if you are in a larger acoustic environment.
