ROOM SIZE

Function .................... This parameter adjusts the apparent size of the surround sound field. The larger the value, the larger the surround

sound field becomes.

Control Range ........... 0.1 - 2.0

Description ................ 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.
