HLT Containers

Head-loop-tail containers are for fancy LOOPING sounds. They can contain 1, 2 or 3 items. If there’s only 1 item, that one is automatically set to be looping. If there’s at least 2 items, the first item is a “head” and the second one is a “loop.” They play at the same time when you play the sound, but the “head” sound is allowed to end while the “loop” sound continues on. We would use this for music, for example to have an intro that played once and then a looping section that followed it. If you have 3 sounds, the last one is a “tail” that plays once when you STOP the sound. We would use this to make an outtro to music that was ending.

• LpDelayIn: Sets a delay, in SECONDS, for the loop to start after the head.

• LpDelay: Sets a delay for the loop to stop after the sound stops and the tail begins to play.

• L-T: changes behavior so that a HLT containing 2 sounds is a loop and a tail instead of a head and a loop.

Also notably, fadein and fadeout affect only the "loop" child, so altogether this gives you nice tools to create a really precise transition from a head to the loop and from the loop to the tail. We used this feature a LOT to make the singing sound just right in Wandersong.
