3-2. DESCRIPTIONS 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).
●
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:
Adjusts the delay between the direct sound and the first reflection
heard by the listener.
Control Range:
1 – 49 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.
