DIGITAL SOUND FIELD PARAMETER DESCRIPTIONS
■
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.
■
P. INIT. DLY (Presence Initial Delay)
Function
This parameter adjusts the delay between the direct sound and the first reflection in the presence sound field.
Control range
1 – 99 ms
Description
The larger the value, the later the first reflection begins.
■
S. INIT. DLY (Surround Initial Delay)
Function
This parameter adjusts the delay between the direct sound and the first reflection on the surround side of the sound field.
You can only adjust this parameter when at least two front channels and two rear channels are used.
Control range
1 – 49 ms
Description
The larger the value, the later the first reflection begins. You can only adjust this parameter for the Dolby Digital and DTS
signals.
