So an interesting fact about WWTP radio at Stealth that I've not seen posted here (and not sure how well known it is), is the way in which it originally* worked.
The system comprised of two media players (Golding DMS3000 units for fellow AV nerds
); one for jingles, one for music tracks. Each was set to play in a random order (but complete all tracks before starting again in a new random order).
One player would trigger, and play a random jingle. The end of this audio file would create a trigger sent to the other media player, to play a random music file. The end of that audio file would create a trigger sent to the first media player, to play a random jingle... and so on and so on.
In this way, you get a random mix of music and jingles, constantly changing, never in the same order, and thus having the illusion of being extremely long! I mean it was extremely long - with over 45 jingles and 150 music files - but the random nature just added to the illusion. Ingenious really.
* - in later years, it was definitely just a single long mix-down track - in fact I've no idea how long the above lasted for, though I imagine a fair few years from the ride's opening in 2006. My guess is that it would've been replaced with the simpler single mix-down track around the time Project Link occurred, linking all the park's audio infrastructure, around the 2013-15 mark.
