39 English 3-1. SELECTING AND EDITING PR OGRAM P ARAMETERS WHA T IS A SOUND FIELD? In order to e xplain the impressiv e functions of the DSP system, we need to first understand what a sound field really is . What really creates the rich, full tones of a live instrument are the multiple reflections from the w alls of the room.
In addition to the “TYPE” parameter which selects the sub- programs within each sound field prog r am (e .g. “Hall A in Europe” and “Hall B in Europe” for prog r am 1, “CONCER T HALL 1.

● 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 .
