English 3-2. DESCRIPTIONS OF THE DIGITAL SOUND FIELD PARAMETERS Not all of the following parameters are found in every program. q INIT DLY (Initial Delay) q 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. 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 Changing this parameter from 1 to 2 increases the apparent volume of the room eight times (length, width, and height all doubled). 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.
