Sound Effects 101
Surround Editor
Graphics: The blue circles are the loudspeakers -- three in front (right, left and center)
and two at the back (right and left). The red circle is the position of the acoustic
source, as perceived by the listener. Place the acoustic source in the space by shifting
the red circle with the mouse; downward motion moves it to the rear, upward motion
moves it forward. The preset position is at the back and centered. This is the "pure"
surround signal.
Surround active: Activate the Surround Mode and the second track opens
simultaneously. Audio material on the second track (‘surround’ in the track display)
can now be positioned in the space.
Width: Determines the dimensions of the sound field. The sound field is made up of
the concentric circles that clarify a drop in the signal level dependant upon the
distance from the acoustic source. A circle corresponds a drop in the dB level. The
smaller the width, the smaller the sound field (and the faster the signal level drops as
the distance from the acoustic source increases)and subsequently, the virtual space is
perceived as being larger.
Switch different items of the display from visible/invisible:
Output dB: Relative level in dB at the individual loudspeakers (0db = full level, -90 dB
= silence)
Loudspeaker names: Name of the loudspeakers according to their position in the
space
