SETUP
Setting sound program parameters (Sound Program menu)
Liveness
Surround Liveness
Surround Back 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 an audio
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.
Reverb 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.
Reverb 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.
