Room size. Preseiiee, >Liirouno, iu;ci surroimc Ixiek room >i/e. Aojiisi> it;e apparent size of the
surround sound field. The larger the value, the larger the surround sound field becomes. As the
sound i-s 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 betw^een 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.
When you adjust the room size parameters, w'e also recommend that you adjust the
corresponding initial delay parameters likewise. This adjustment is especially effective for the
CINEMA DSP programs.

Liveness. Surround and surround back sound field liveness. Adjusts the reflectivity of the virtual
'kjj::rcc walls in the hall by changing the rate at w'hich the early reflections decay. 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”, w'hilc a roont with highly reflective surfaces is referred to as “live”. This paranteter
lets you adjust the etirly reflection decay rate and thus the “liveness” of the room.
