DESCRIPTIONS OF THE DIGIT AL SOUND FIELD P ARAMETERS Not all of the f ollo wing par ameters are f ound in e v ery program. ● ROOM SIZE How it Aff ects the Sound: Changes the apparent size of the m usic v en ue . The larger the v alue , the larger the simulated room will sound. What it Does: Adjusts the timing between the early ref[...]

● LIVENESS How it Aff ects the Sound: This parameter changes the apparent reflectivity of the w alls in the hall. The early reflections from a sound source will lose intensity (deca y) m uch f aster in a room with acoustically absorbent w all surf aces than in one which has mostly reflectiv e surf aces . A room with highly reflectiv e surf aces i[...]
