Strange scraping sound on touchdown

On a few aircraft, I hear a terrible scraping sound .... Like a wheels-up landing (never done one, but that's the best way I can decribe it).

It happens with certain aircraft only, but with those, it happens all the time on all surfaces (tarmac or carrier deck). I haven't done a complete inventory of which are affected - so far, I've found it on Rob Richardson's Vampire, Flying Stations' Sea Fury, to name a few. In the case of the Sea Fury, it does it with either the stock sounds or Nigel's soundest.

I want to say maybe Falcon409 may have raised this before - searched, but can't find the thread.

Sim is FSX Acell.

Thanks!

DL mine was a "water landing" sound with every airplane. To be honest, I hadn't even thought about it for some time. . .and it seems to have disappeared on it's own.:salute:
 
I encountered this in FS9, and traced the source to the effects file.

Here are the first few lines of the offending fx file [fx_tiremark_6.fx].

[Library Effect]
Lifetime=5
Version=2.00
Sound=5
Sound Param=13

It's possible these days for a stock effect file to be overwritten and shared by several a/c.

I would take a look at a specific a/c cfg file, track down the individual effect file, and examine it with an editor like notepad. I just deleted the above [Library Effect] and never had a problem since.

Dl have you posted anything about this in the Flying Stations Forum ??

At the moment you are the only one with this problem, I certainly do not have it with any of the sound setups I have tried though I have have not tried Rob Richardson's Vampire yet.

The sort of sounds you describe will come from the main FSX sound folder not the aircraft sound folder.

As far as I can see there is nothing wrong in the sound.cfg of the ones you have a problem with.

Have you done anything in the contact points section as the sounds you mention can be triggered from there
 
While I found [fx_tiremark_6.fx] in Fs9 effects I can not find it in FSX effects.

As far as I can see nowhere is that effect being called for in the Sea Fury.

An effects file causing that irritating touchdown sound. Who knew! Thanks for the lead WarHorse. For me, it was "fx_tchdwn_s" that had been replaced at some point. With the default file back in place, touch down sounds are back to normal.
 
Ranger75, is this anything to do with DL's sound problem ?? do you have the same problem with the Sea Fury and Vampire ???

In FSX I have this for touchdown effect
fx_tchdwn_s.fx

Thanks all for the replies. Will review the fx files in question.

Rich, I didn't post on Flying Stations because I am not convinced that it had to do with the Fury per se. It was fine a few days ago, and now it isn't.

Cheers!

DL
 
DL if you had said this in the first place it would have saved me wasting a lot of time.

The release sounds have engine sounds only so no touchdown or scrape sounds from there and neither does that sound.cfg call on FSX default sounds.

DL, can you post the [EFFECTS] section from your Sea Fury aircraft.cfg, see what we can work out from that.
 
I suspect the noise is the same one DL is trying to get rid of, but it could just as well be an entirely different problem. The scraping noise was heard with the RealAir Dukes and other aircraft at some but not all airports. I don't have the Sea Fury.
 
Ranger75, are you using FSX or Fs9.

I would have thought that sound you have should be on all airports.

Have both installed, but this issue is specific to FSX. The default file size for fx_tchdwn_s is 3.5 KB and the 'corrupted' one is 2.5 KB. I don't know where the replacement came from and when it was installed. How and why an effects file supposedly to do with tire smoke can cause a scraping noise at some airports and not at others is just one of those always amusing flight sim mysteries!
 
Ranger75, 3.5 kb is what I have for fx_tchdwn_s_fx with no sound mentioned in it.

It would be interesting to see what your 2.5 version contains but I rather suspect nothing sound related there and your sound problem is elsewhere.

Have you tried moving your 2.5 version out of FSX to desktop to see if you still have the problem and move it back if it does'nt fix it.
 
WarHorse, ok thanks that's what I thought.

[fx_tiremark_6.fx] is not a default Fs9 or FSX effect it must have been introduced from elsewhere the Fs9 Sea Fury is one that loads it in Fs9 that incarnation will not work in FSX which is possibly why it does not appear in FSX effects.

Do you have the Fs9 Sea Fury ???

FS9. Not ready yet for FSX.

I was stumped looking for the sound file causing the irritating touch down sound at some airports. When WarHorse identified an effect file as a possible culprit, I looked for changed file sizes and dates in that folder, and found fx_tchdwn_s. The ‘corrupt’ one does indeed refer to a sound file [ai_touchdown2.wav] which is not in my sound folder.<o:p></o:p>
Flying circuits at CYSN in the Duke, default Baron and other aircraft, with the good and then the bad fx_tchdwn_s files installed in FSX, led to the conclusion that this was the source of the problem, at least on my computer. We await the reply from DL to see if this is the same one there! <o:p></o:p>
 
Thanks Rich, (and all!)

Just literally dashing out the door - can't fire anything up to try the fixes till tonight - but as per Rich's request:


[EFFECTS]
wake=fx_wake
wetenginewash=fx_spray
water=fx_spray
dirt=fx_tchdrt
touchdown = fx_tchdwn_s, 1
windshield_rain_effect_available = 1

I often edit the touchdown effect - I hate that big white billowy cloud one often gets with most a/c - usually with the Alphasim Scimitar's, has a nice puff of smoke. But in this case, I left it stock ...

Thanks again!

DL
