Today was my first visit to Thorpe since the IMA Score audio was introduced. I have to say, having heard it on the CD I'm actually quite disappointed with how it sounded at the park.
A lot of the equipment around the park sounded worse for wear but whether or not that's faulty amplifiers or cabling rather than phsyical speakers I don't know. The quality and coverage is all over the place.
The Nemesis Inferno station track (which I hadn't heard until today) sounded absolutely fantastic and that was what I was most impressed with. What has happened to all the sound systems on the flat rides though? Rush, Vortex and Detonator had their soundtracks but they were barely audible; Samurai was the complete opposite with the music being so loud it distorts the speakers. Quantum and the Swarm's station just had nothing at all.
In terms of park-wide audio it doesn't seem to create a real ambience, for example around the Lost City flats it's not a continuous ambience but more just two speakers which are extremely loud if you're standing right next to them and nothing else. The same for Dome, absolutely booming in the toilets but gentle ambience upstairs. No consistency. Anyone who's ridden Helix at Liseberg should have an appreciation of how much of a difference the audio can have with proper continuous coverage rather than what Thorpe have got.
A shame really. Not much point having all these specially composed soundtracks if you've not got a decent sound system to play it on.
