mDescriptions of the digital sound field parameters

Not all of the following parameters are found in every program.

●ROOM SIZE

How it Affects the Sound:

Changes the apparent size of the music venue. The larger the value, the larger the simulated room will sound.

What it Does:

Adjusts the timing between the early reflections. Early reflections are the first group of reflections you hear before the subsequent, dense reverberation begins.

Control Range:

0.1 – 2.0

Standard setting is 1.0.

Changing this parameter from 1 to 2 increases the apparent volume of the room eight times (length, width, and height all doubled).

P. ROOM SIZE (Presence Room Size)

Adjusts the apparent space size of the front presence sound field. The larger the value, the longer the interval between reflections becomes, which increases the depth of the sound source.

S. ROOM SIZE (Surround Room Size)

Adjusts the apparent space size of the rear surround sound field. The larger the value, the larger the surround sound field becomes.

	Time		Time			Time
Small space						Large space

●INIT. DLY (Initial Delay)

How it Affects the Sound:

Changes the apparent distance from the source sound.

Since the distance between a sound source and a reflective surface determines the delay between the direct sound and the first reflection, this parameter changes the location of the sound source within the acoustic environment.

What it Does:

P. INIT. DLY (Presence Initial Delay)

Adjusts the delay between the direct sound and the first reflection on the presence side of the sound field. The larger the value, the later the first reflection begins.

Control Range:

1 – 99 milliseconds

Adjusts the delay between the direct sound and the first reflection heard by the listener.

Control Range:

1 – 99 milliseconds

For a small living room this parameter would be set for a small value. Large values for a big room. Larger values produce an echo effect.

S. INIT. DLY (Surround Initial Delay)

Adjusts the delay between the direct sound and the first reflection on the rear surround side of the sound field. The larger the value, the later the first reflection begins.

Control Range:

1 – 49 milliseconds
