To add sound to a virtual world, use a Sound node. You can include an
AudioClip node in a Sound node. For an
AudioClip node, use a mono or stereo WAV file in uncompressed PCM
format.
To listen to the sound, use a computer that supports sound. For details, see Listen to Sound in a Virtual World.
Note
A stereo sound source retains its channel separation during playback. Simulink®
3D Animation™ attenuates the sound based on
the distance of the viewer from the sound location. The relative position of the viewer to
the sound location and the viewer direction in the virtual world do not affect the stereo
channels. There is no impact even if the Sound node has the
spatialize field set to true.
The following code adds to a virtual world a sound that switches on and off based on a logical signal.
DEF SoundSwitch Switch {
choice [
DEF MySound Sound {

url "sound/crane_run.wav"
loop TRUE
