The recent Cl47 profile release is very welcome, I am little disappointed with the horn sounds however. I figure some of the recordings have come from locomotives approaching at speed, or from a distance. The Doplar effect is quite obvious on F3. Not sure where the F2 samples came from. I'm getting a sick cuckoo with a party-horn vibe. I can see that in certain circumstances, the F3 horns would work quite well (large, fast continuous loop layouts). I have a small depot layout so the aggressive, distant or novelty horns do sound rather odd when things don't get much above crawling speed. My suggestions for consideration: Properly group horn sounds between the two horn functions. F2 for bog-standard, short blasts to average length two-tones. (For starting, shunting and slow-speed layouts). F3 for the novelty, long, distant and fast approaching tones. (For showboating and scale 3,000mph passes). I think AFC control only use F2 samples? If not, I think that would also be a good idea. Replace the Cl47 horns with more typical sound samples. I fully appreciate that this is probably more complicated than I understand. The sound engineers can't possibly know the intricacies or quirks of each loco/unit they recreate. There's also the issues of obtaining quality samples, permissions, editing, deadlines and the other absent profiles which will take priority once a profile is released. To support my final suggestion, here's a link to a video I recorded which includes what I would consider an average Cl47 high-low tone. Suitable for the F2 suggestion I mention above.
I must mention, I have no idea if the video above is of a suitable quality. I'm not suggesting Hornby use it. It's just a useful comparison to the samples included in the current version of the Cl47 profile. Other than that, I'm really happy my 47's don't sound like MTU HSTs anymore!
