I LIVENESS
Function
This parameter adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the early reflections
decay.
Control range 0 – 10
Description
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". The LIVENESS parameter lets you adjust the early reflection decay
rate, and thus the "liveness" of the room.
