DIGITAL SOUND FIELD PARAMETER DESCRIPTIONS

■ LIVENESSControl Range 0 – 10

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 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.

■ S. DELAY (Surround Delay)

 

Control Range 0 – 49 msec (The range

 

 

 

 

 

 

 

 

depends on the signal format.)

Function:

This parameter adjusts the delay for surround signals and surround sound field.

■ S. INIT. DLY (Surround Initial Delay)

 

 

Control Range 1 – 49 msec

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.

 

 

 

 

 

 

 

 

■ S. ROOM SIZE (Surround Room Size)

 

 

Control Range 0.1 – 2.0

Function:

This parameter adjusts the apparent size of the surround sound field.

■ S. LIVENESS (Surround Liveness)

 

 

 

Control Range 0 –10

Function:

This parameter adjusts the apparent reflectivity of the virtual walls in the surround sound field.

■ RC INIT. DLY (Rear Center Initial Delay)

 

 

Control Range 1 – 49 msec

Function:

This parameter adjusts the delay between the direct sound and the first reflection in the rear center

 

sound field.

 

 

 

 

 

 

 

 

■ RC ROOM SIZE (Rear Center Room Size)

 

 

Control Range 0.1 – 2.0

Function:

This parameter adjusts the apparent size of the rear center sound field.

■ RC LIVENESS (Rear Center Liveness)

 

 

 

Control Range 0 – 10

Function:

This parameter adjusts the apparent reflectivity of the virtual wall in the rear center sound field.
