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.

When you adjust the room size parameters, we 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 liveness. Adjusts the reflectivity of the virtual walls in the
hall by changing the rate at which 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", while a room with highly reflective surfaces is referred to as "live". This parameter lets
you adjust the early reflection decay rate and thus the "liveness" of the room.
