Liveness

Liveness. Surround and surround back liveness. Adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the

Sur. Liveness

early reflections decay. The early reflections of a sound source decay much faster in a room with acoustically absorbent wall surfaces than

SB. Liveness

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.

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.

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.
