Heljan O gauge Class 55 - "Deltic" - customised DCC sound project (v3)

In a previous video, I showed my attempt to do justice to the sounds of the legendary Deltic locomotive, using a Legomanbiffo sound project and two, Hi-Fi quality, component speakers from Visaton (50mm cones @ 8ohms and custom-built enclosures - both mounted in the body, not the fuel tanks). I wasn't really happy with the result which left me wondering if it was the installation that was the problem and/or the sound reproduction. Spoiler alert: it was a bit of both! I discovered (since v2) that, despite observing PCB/speaker markings and wire colours, the two speakers were connected out-of-phase - in other words, they were doing their best to cancel out each other's sounds. As soon as I remedied this, the difference was astonishing - loud AF! I've reduced the master volume to around 75% to stop my ears bleeding ... This video demonstrates "Take 3" where I've used a freely available ESU project file (S0399) as a basis but then - using their LokProgrammer software - completely rewritten the sound schedule to try to better reflect engine response to throttle inputs with the intention of prioritising sound response over locomotive speed, for example, a reduction of throttle by just one speed step will automatically return engine sounds to idle (Paul Chetter/Zimo style). At the same time, the volume of the included sound samples have been adjusted so that, as engine revs increase, so does amplitude - most commercially available DCC diesel sound projects are volume equalised (so idle is as loud as "full chat") and this sounds noticeably wrong to me in larger scale models. Using a new v5 decoder firmware feature, treble frequencies have been significantly attenuated here - there's a lot of static/white noise on the engine sound samples included with the ESU project; I can't edit these proprietary sounds but I have attempted to turn down the "hissssssssss". This customised sound project also attempts to simulate an engine/generator overload situation - if the throttle is turned up to max. from low speed, the engine revs. will increase but then cut-out and return to idle; this sequence repeats until a higher speed is attained or throttle input is reduced (not sure how realistic this is but the intention is to try to get users to drive a bit more sympathetically). I think the results definitely sound better with this speaker set-up but this is still very much a "work in progress". A future version will, hopefully, also incorporate load-dependent sound responses (another new firmware feature) ... Anyway, we hope you like it. Please let me know what you think in the comments.
