Hi Bill One stab in the dark I will ask is if the SRN-4 Hovercraft sounded anything like it? It was powered my a marine version of the Proteus... Not really - the SRN4 was much noisier! (MkII had 4x19' props, MkIII had 4x21' props, and both had 4x11.5' 12-bladed lifting fans). I only travelled on SRN4s a couple of times in the 1970s, but have the distinct impression that they were noisier inside than the Britannia was outside.

Thanks Bill I have many Princess clips and all you really hear is the props and as such it sounds almost Shackleton. The PPrune links are a good read and confirms one thing. I found pics of Brits with two of each props but was told they never mixed them which surprised me as often they are mixed in matching pairs., during tyransion times. A similar thing with Viscount 701 of BEA that changed to the Dart 506 and the rounded pointy prop instead of the Cutlass Blade of the Dart 505 setup. They were changed two at a time, one each side matched and so I thought the Britannia were likely to have done the same. I'll keep my eyes and ears open but as mentioned in one of those threads, good info on the net is not readily available and I was much delayed before I had good three views. I never did get good plans for the CL-44 but have managed to use odd pics, drawings and of course Britannia bits ;D Garry

Hi all, The Avion DVD "Ringway, Vintage Manchester Airport" has several short views of Britannias, complete with (dubbed) sound. I don't know if these sound bits are true Proteus, but they do sound quite different from anything else on the DVD. Other Avion videos also have some Britannia clips that sound similar - perhaps that's a good sign. Hope this helps,

Hi Tom The problem I have is no experience of the true sound so I can't judge if the sounds are dubbed correctly or real. On some Avion DVD where I do know the subject, there have been errors in their dubbing. Thanks for that though Garry

There is a Video, don't know if it is on DVD, called 'Farnborough the Glory Years', it may be on that.

Cheeers Simon I have some Farnborough stuff.....possibly that one but nothing conclusive. I also don't know how well the sound reproduces as on some types I do know the sound didn't come out the same on early recording as in real life....Bristol Freighter for example seems to lose the fan whine very audable ahead of the chatter. But it's not really any good me listening to anything, I need someone who know to point me at something that sounds just right. In theory I could have every recorded Britannia sound in history but would not know which one was right ...unless of course they all sounded the same. The big props would probably have done something at distance. An HS.780 sounds just like a 748 right close but turning away a mile distant after take off it can sound almost Tyne like as it is the large prop drowning the Darts. A Dash Seven at altitude sounds like a CL44 as all that can be heard is prop throb....although not so heavy it is a lot heavier than when you hear them at the airport. Because of all this I don't have a starting point sadly Garry

Hi Gary, I run into this situation all the time - no one knows the real answer. At some point you just have to go with what you have, and trust your gut. You can always improve it later.

Indeed Tom It's not urgent at the moment but it is starting to look that way. Just in the meantime I'll put out feelers Garry

Hi Garry, I struck on this site ( www.1st-take.com/product.asp?P_ID=124 ) which features the DVD "The Bristol Britannia Story". I have to buy that DVD yet, but I get the impression that it might be helpful. There is a wee clip which shows the first visit of a Britannia in South Africa (tests in tropical conditions). One take (in colour) shows a Brit during a fly past, probably that same aircraft, with sound. That sound is very familiar to me from the Monarch Britannias I saw and heard in the early 1970s. This purr without any turbine whine was one of the features of the type that really struck me. Perhaps there is more Britannia sound on that DVD. Might be worth a purchase. Cheers, Maarten

Garry, I agree with Tom. You have to just start somewhere and the rest of us will do our best to help get it right. It's already pretty well certain that the interior sound ought to be virtually nil, just the wind/air flow, and the exterior a mixture of hiss/buzz/rumble ;D. It's a while since I used FS Sound Studio, don't know how useful it is but I'm currently using a programme called WavePad to adjust sounds to my liking. You can easily adjust the pitch of each .wav. I reckon you could start with say one of the better DH7 or 8 sounds and just increase the pitch. By the way, I've listened again to the one that Wolfgang mentioned. www.youtube.com/watch?v=RWw1fRW7x4cI'm coming round to the view that the taxi sequences at 02:14 and 02:48 and the take off at 03:52 are indeed true recordings, but for reasons of recording technicalities, just seem to have a bit too much hiss, not really very helpful. It may well be evidence that the sound changed depending on where you were in relation to the prop alignment but that's not something FS9 can deal with. Bill

Maarten's comment,
"This purr without any turbine whine was one of the features of the type that really struck me".
I agree entirely. So it's now purr/hiss/buzz/rumble! Just joking - I really wish I could describe it better. I can hear it in my mind and that deep purr/rumble keeps coming back. That's why I mentioned a while back that the C130/Herc isn't so different at least in fly by. Does anyone else think so?
And there is surely something else useful in this 80 minute DVD?
Bill
