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.
Description: The early reflections of a source sound 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.
Control range: 0 – 10
■ 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 surround
channels are used.
Control Range: 1 – 49 msec
■ S. ROOM SIZE (Surround room size)
Function: This parameter adjusts the apparent size of the surround sound field.
Control Range: 0.1 – 2.0
■ S. LIVENESS (Surround liveness)
Function: This parameter adjusts the apparent reflectivity of the virtual walls in the surround sound field.
Control Range: 0 – 10
■ SB INI. DLY (Surround back initial delay)
Function: This parameter adjusts the delay between the direct sound and the first reflection in the surround back
sound field.
Control Range: 1 – 49 msec
■ SB ROOM SIZE (Surround back room size)
Function: This parameter adjusts the apparent size of the surround back sound field.
Control Range: 0.1 – 2.0
■ SB LIVENESS (Surround back liveness)
Function: This parameter adjusts the apparent reflectivity of the virtual wall in the surround back sound field.
Control Range: 0 – 10
