Sound Node
VRML 2.0 supports not only 3D graphics but also 3D sound. Using the Sound node you can not only provide a location for the sound source but also the spatial properties of its propagation.
The following fields are present:
source specifies either an AudioClip node, for wave and midi sounds, or a MovieTexture node, for mpeg sound.
location specifies the location of the sound source in the local coordinate system in which the Sound node is included.
intensity defines the volume of the sound, must be between 0 and 1, where 0 corresponds to silence and 1 to full volume.
direction indicates the direction in which the sound source is pointing.
priority provides a way to define the relevance of the sound. This field is useful if there are no sound channels available, must be between 0 and 1. Higher values indicate higher priorities.
spatialize indicates if the sound should be treated as 3D or ambient sound. If TRUE the sound is 3D else the sound is not localized, i.e. you can hear the sound in both the left and right channels of your stereo regardless of your position.
minBack, minFront: specify an inner ellipsoid within which the sound is heard at the intensity specified.
maxBack, maxFront: specify an outter ellipsoid. If the user is outside this ellipsoid the the sound is not heard. When between the ellipsoids the sound is attenuated as one travels from the inner ellipsoid to the outter ellipsoid.
