SOUND FIELD PARAMETER DESCRIPTIONS

LIVENESS (Liveness)

Function:

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. INIT. DLY (Surround initial delay)

Function:

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 to 49 msec

Function:

Adjusts the apparent size of the surround sound field.

Control Range:

0.1 to 2.0

S. LIVENESS (Surround liveness)

Function:

Adjusts the apparent reflectivity of the virtual walls in the surround sound field.

Control Range:

0 to 10

SB INI. DLY (Surround back initial delay)

Function:

Adjusts the delay between the direct sound and the first reflection in the surround back sound field.

Control Range:

1 to 49 msec

SB ROOM SIZE (Surround back room size)

Function:

Adjusts the apparent size of the surround back sound field.

Control Range:

0.1 to 2.0

SB LIVENESS (Surround back liveness)

Function:

Adjusts the apparent reflectivity of the virtual wall in the surround back sound field.

Control Range:

0 to 10
