Hi all, does anyone else have this sound, it only happens on the deck, no wind or other things it could be, but it doesn't do this in 1.5

I noticed that my friendly Mirage in Multiplayer while on idle engine has a constant afterburner on/off animation and sound.

 

Really annoying

 

Same here. We had our training today and were all on idle (after ramp start) and heard the afterburner sound. In the F2 sight, there was also an popping afterburner animation. Same in the air.

Same problem overhere in 2.0 after the update tonight. Only in the cockpit. It starts when you move the throttle (after reaching 11%). It disappears more or less when you change your view down to the ejection seat. Strange and don't have it in 1.5.2 (not updated yet I know).

If I'm listening at the wingman's Mirage, it doesn't seem to make that noise, it's only the user's.

Weird.

its a animated switch sound thats bugged i think in mirage click click click sound looped.

 

already been noted i think.

 

We're not talking about that issue here ... this is another issue with the Engine afterburner going on/off when your engine is idling

thats what the bug is as well afterburner bug and audio with it.

 

The problem has with this wav file: CockpitAfterburner.wav in the following path

DCS World 2 OpenAlpha\Sounds\Effects\Aircrafts\Engines

and the corresponding sdef file (DCS World 2 OpenAlpha\Sounds\sdef\Aircrafts\Engines).

When you "rename or remove" the wav file or sdef file the problem is gone. However it should function properly.

To be honest I adjusted both the cockpitafterburner.wav and that corresponding sdef. I returned the original (wav and sdef) files. It was much better inside the cockt but not gone. Outside you can still hear that sound.

Maybe this helps for the time being. I mean to disable the wav of sdef file till they patch it.

I'll take a look at this guys, but I have the feeling that the issue is with the game engine, not the M-2000C's engine :P

 

I always like to adjust engine and related wav files to my own taste. The Mirage has its own sound files (Mod/M-2000C/Sounds/effects) However most of these sound files are not used, as the sound files must correspond with the sdef files (Mod/M-2000C/Sounds/sdef). You will see that a part of the sound files are used. Only cockpit related sound files (such as knobs, warning signals etc).

 

What the Mirage uses, are the "default" DCS engine files. The Mirage uses the SU-25 engine wavs. The front/back/around engine files of the SU-25. These files are also used by the Hawk, the C-101 aviojet, the Mig 21 (partly). So you actually can say that these are the "default jet engine" wavs. I tried to understand how DCS adresses the engine wavs. With the sdef for sure, but that is not the complete story. Maybe someone knows how it works (the complete addressing of sound files)!!!!!

 

The Mirage engine files (\DCS World 2 OpenAlpha\Mods\aircraft\M-2000C\Sounds\effects) are a copied from the FSX structure (you can find the sound.ini and sound.cfg of FSX in the list). I think all good sound files. but still must be addressed to the M-2000C with the respective sdef files. Of course it is beta and it will come along. So I can live with the semi "su-25 default engine files".

However the popping sound can be reduced (or it even stops) with deleting or renaming the COCKPITAFTERBURNER.WAV in the \DCS World 2 OpenAlpha\Sounds\Effects\Aircrafts\Engines DIR (or rename/delete it in the \DCS World 2 OpenAlpha\Sounds\Sdef\Aircrafts\Engines DIR. Of course backing up the files.

 

Well it is more a story what I discovered how the engine and related files work, but maybe indeed it is a DCS engine related issue that effects the M-2000C

This bug wasn't there during the first release

____

 

On a side note I would like to put my theory out there ... now it may totally be wrong or whatever but I guess it could help so ...

Ever since the last patch (the one that happened after new years) the engine popping sound started

 

Personally I don't have it inside my cockpit but outside and it sounds as if my plane is using afterburner on/off without actually moving the power setting.

Now what I think happened is during that patch when the "Engine setting is now affected by Throttle position not inputs" is where the bug happened (At least that's what I think)

Might be worth to take a look at it if you're not sure I don't really know what you guys did there so ...

 

So yea that's why we get cases where a friendly in multiplayer sees me with my Afterburner On/Off animation and the popping sound even though I'm idle and not moving

It's interesting that the M2000 module would use the Su-25 engine sound files. I've been flying the Su-25 quite a bit lately and have not encountered the "idle popping" noise that's present in the Mirage.

After some testing and removing wav files in Sounds/Aircraft/Engine dir I discovered the problem of the popping sound. It is caused the following wav file in \DCS World 2 OpenAlpha\Sounds\Effects\Aircrafts\Engines DIR "PlaneFarNoise.wav". First I thought it was the CockpitAfterBurner.wav. But after some testing over and over I am convinced that this wav file is the problem.

I think the corresponding sdef file has to be adjusted as this file is controlling the PlaneFarNoise.wav. I partly understand how these sdef files work and these setting can be changed.

However I am not THE expert of course. How more GAIN value (sdef file can be opened with wordpad) how more popping you will get. But that is obvious. But there are also cone and radius (inner and outer) values which can be changed but I do not know how that works. Perhaps someone knows, so the sdef file will work correct and we don't have that stupid sound anymore.

I did some changes myself as I took another wav file PlaneFarNoise and adjusted the gain factor in the sdef file. However the gain value is low and this effects the fly by (F3) application. After 1.5 nm from the spot you activated F3 you will not hear the jet engine anymore. Well that's it for now.

The popping afterburner sound has in my opinion nothing to do with the sound file. Because the 3d model of the Mirage also playes the 'afterburner' animation. This for example can be seen in SimShaker which uses data from the 3d model to play the effect...

Maybe we misunderstand each other. The strange popping sound or maybe it is better the call

a recurring crackling sound when you throttle back to idle. When throttle up the cracking sound will be overruled with the other engine sounds which become louder. I have attached a .trk file which can put in: C:\Users\...\Saved Games\DCS.openalpha\Tracks (this is the path in my case) or whatever Dir of your saved games. You will hear what I mean. It is crackling sound and when deleting/removing the PlaneFarNoise.wav it is gone. I have the problem in all the DCS version DCS world/openbeta and DCS 2.0.1. It started after the first update for World 2.0 and when 1.5.2 (stable and beta) were updated the same problem of the crackling sound were audibly as well

I get the popping sound and also see M2000 in multiplayer going in and out of burner when idle. Either that or they've forgotten the parking break ;)
