Sound field parameter Features
INIT.DLY
P.INIT.DLY
S.INIT.DLY
SB INIT.DLY Initial delay. Presence, surround, and surround back sound field initial delay. Changes the
apparent size of the sound field by adjusting the delay between the direct sound and the first
reflection heard by the listener. The smaller the value, the smaller the sound field seems to the
listener.
y
When you adjust the initial delay parameters, we also recommend that you adjust the
corresponding room size parameters likewise.
Control range: 1 to 99 ms (INIT.DLY and P.INIT.DLY)
1 to 49 ms (S.INIT.DLY and SB INIT.DLY)
ROOM SIZE
P.ROOM SIZE
S.ROOM SIZE
SB ROOM SIZE Room size. Presence, surround, and surround back room size. Adjusts the apparent size of the
sound field. The larger the value, the larger the surround sound field becomes. As the sound is
repeatedly reflected around a room, the larger the hall is, the longer the time between the original
reflected sound and the subsequent reflections. By controlling the time between the reflected
sounds, you can change the apparent size of the virtual venue. Changing this parameter from one
to two doubles the apparent length of the room.
y
When you adjust the room size parameters, we also recommend that you adjust the
corresponding initial delay parameters likewise.
Control range: 0.1 to 2.0
