See Loading and Playing Sounds and Music for basic information on how to load and play sounds.
Sound intervals play sounds from inside an interval. Like actor intervals, sound intervals have a loop parameter and the ability to be paused. Sound intervals also have volume and start time parameters.
mySound = loader.loadSfx("mySound.wav") myInterval = SoundInterval( mySound, loop = 0 or 1, duration = myDuration, volume = myVolume, startTime = myStartTime )
The looping provided by the sound interval is not clean. There will be a pause between loops of roughly a tenth of a second. See Manipulating Sounds for a better way to loop sounds.
