In the constructor, the sound is loaded and assigned to a sound channel
(channel). A SoundTranform object (transform) is also
created. Its first argument sets the volume at 50 percent (the range is 0.0
to 1.0). Its second argument set the panning. Here, panning is set to 1.0, which means
the sound will only come from the right speaker. In order for these setting to
take effect, the transform SoundTranform object is
assigned to the sound channel's souundTransform property. (There is
limited error handling written for this exemplo.)
