AI Aircraft Sounds

Recommended Posts

Hello. I'm hoping someone can answer this quick question for me.Is there any performance loss in giving the AI aircraft sounds? I know there are some pay products out there to provide somewhat acurate sounds to AI aircraft and those sounds are only for AI aircraft.What is the main issue with giving AI planes aliases to user aircraft sounds?Thanks very much!

What is the main issue with giving AI planes aliases to user aircraft sounds?You can do that in FSX, you cannot do that in FS2004.FS2004 AI aircraft only use sounds a set of files in the main sound folder - they all start with AI_*.wav

I don't think that's exactly true because I can add sounds to the AI aircraft sound folder and they work just fine. I was just trying to find out what the drawback to this is as there must be one, right?

AI aircraft use a very simple standard sound set in FS9. Even a flyable aircraft (with it's own dedicated sound folder) which is being used as an AI (not recomended) will use this standard sound set. FS9 will simply ignore any specific sound folder contents whether aliased from another aircraft or not. The only thing you could do is to change the standard sound set sounds but these will be played for all aircraft within each catagory, e.g. jets, piston engines, etc.This is also the reason why AI aircraft should only have the following folders/files:ModelTextureAircraft.cfgXXXXXX.airAnything more than that is pure ballast for your system.Hope this helps.Hans

When you say it's not recommended, why is that? That was why I asked the initial question.Some of my AI aircraft do have sounds but I would like to add sound to the rest as well.

Hi,As stated above, the Sound folder inside the plane's folder is NOT used for AI aircraft, only a small list of sounds in the main FS SOUND folder. A plane that you fly will use the Sound folder, but when used as an AI plane it is *not* used.Flyable planes used as AI aircraft have two problems - first is that they are not built with multiple levels of detail (LOD), and thus tend to be hard on frame rates. Second, they often do not fly well as AI aircraft. No harm in trying it out, though.Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

I was talking about for AI planes. If I put a "sound" folder inside an AI aircraft that contains a sound.cfg file that has an alias for another aircraft's sound folder it works perfectly fine.I'm not sure how you have gone about trying this but that's how it works for me.So, If I create this folder for an AI plane and point it to another aircraft, in this case perhaps a flyable plane, that particular AI plane now has and uses the sounds for that flyable plane. Now, obviously I don't care about the majority of them. Things like flap sounds, startup/shutdown sounds, etc.

Do a test please - alias a jet AI aircraft to a prop flyable aircraft. Let us know if that works?

I've already done it. Not turning a jet into a prop but have configured AI planes to use other sounds.I don't care if they are not the exact sounds for that particular aircraft. It's just nice to have something there.Kind of getting off topic though. I'm just trying to find out what the down sides are to doing this. People say it's not good to do but I'm trying to find out why.

I tested aliasing an AI Phantom jet's sound to that of the standard flyable FS9 Cessna 172 but as expected, it didn't work.So to definitely answer your specific questions: The "down side" is that it just DOESN'T WORK unless you are using some kind of Hokus Pokus inwhich all experienced FS9 users including myself, would be very interested.Why the use of a flyable aircraft as an AI is "not good" or "not recomended" is correctly answered by Reggie Fields above.Hans

It does not matter how the sound may be aliased.Instead, they use the following sound files which are in your main sound folder:There are 13 files which start with

I think you guys misunderstood me. I wasn't talking about using flyable aircraft for AI aircraft. I was talking about using flyable aircraft sounds for the AI aircraft.

>I think you guys misunderstood me. I wasn't talking about>using flyable aircraft for AI aircraft. I was talking about>using flyable aircraft sounds for the AI aircraft.That is exactly what we have been addressing. AI planes simply do not use anything other than the default sounds as detailed in another response.

What you're saying is that if you alias an AI aircraft sounds to, say, the Lear 45 that AI aircraft doesn't use those sounds?If that's what you're saying then I don't know what to say because it works for me. I have done this with other aircraft as well but I'm not at my machine so can't give specifics.

No, I am not hearing the sounds of the plane I am in if that's what you're asking.If I am able I will try this weekend to narrow down a couple of specifics and report back.

I think all of you may have missed the boat on this one. If you read the original post you will find that this gentlemen is NOT talking about AI aircraft. He is talking about a flyable aircraft (different design from AI aircraft) called by a flight plan using the "title=" statement contained in the flying aircraft's aircraft.cfg file.Normally in an AI aircraft's folder there is no sound folder or sound alias. FS9 will default to the AI sounds. You can put anything you want in an AI aircraft's sound folder and it will still not be used.I this case, I believe you can point the sound.cfg file (flyable aircraft) to anything you want - even a prop sound set running with a jet aircraft - weird but doable.So, I believe you can use a flying aircraft called for in a flight plan. The "aircraft.txt" file could contain the title of the flying aircraft (within its config file). The reason you wouldn't want to do this is because of the size of the default/3rd-party flying aircraft. The aircraft folder is way too large to use for AI. If you don't think that matters try using a POSKY aircraft for AI. I have tried that and man it really drags the system down.The reason I think this works is it seems to me that in the past I used a flying aircraft as AI and one time I was sitting on the ramp and this aircraft passed my location and the sound coming from the aircraft was prop. Unfortunately, the aircraft was a multi-engined jet - Oooooops.fb

You are half right.Actually, I was talking about AI aircraft. Just having those aircraft use sounds from whatever I want.If what you say is true, then why is it some of my AI planes have sound and some don't? I'm not knocking you. I'm just trying to figure it out. And, how do I get the ones that don't have sound to get it? Again, if what you say is true then putting an alias in there won't do anything.

Let's approach this from a different perspective. If we could simply give different AI different sounds, by sound aliasing, then why the need for addon programs to accomplish the same thing? And then why do we only find packages that improve upon the (x)ai_*.wav sounds and nothing else?Carob (I believe you have to sign posts with your real name), if an AI aircraft used as AI (you're not flying it yourself) uses an aliased sound instead of the default AI sound, what is the type of that aircraft? What I mean is, does it appear in the aircraft selection screen or not? I'm wondering if that's the key. If it's non-flyable, AI sound, not, aliasing works.Maybe you can test that out, verify it with the aircraft that is behaving unconventionally. (You can use AirEd or FS Aircraft Typer to check this.)Me, I'm using this package, makes a real difference.> People say it's not good to do but I'm trying to find out why.Where do people say that? If the consensus is that this doesn't work, why would people say it's not good?

I don't think it matters if the aircraft shows in the selection list or not. There are a number of utilities that can change that. I have been using one in particular the last few days as I have been added more AI traffic. I use the tool to make them visible so I can make sure they appear correctly (basically making sure I didn't screw something up)before adding the actual traffic.Let's uses your example... You are using the "ai_sound.zip" file. The benefit to that, I'm sure, is better sounding AI planes vs the default. Okay, what is the downside to using those? Larger files, more system resources, slower FS, etc? That was my initial question.

The file sizes are slightly larger, so there's 'more work' to be done. The performance difference is gonna be negligible however.

I just took a look at all of the files in this package with my Sound Editor (Adobe Audtion).It appears the 1,2,3 versions of each set are indeed exactly the same.If this not acceptable, you might try one of the other packages which are available in the library.I use a combination of the following:aisound_1.0.zip from Avsim andaisnz.zip from Flightsim. They work well for me.

Thanks, Opa. TTYTT, I've used those files and I rarely hear ANYTHING from an AI aircraft -- nada -- silencio. Do you suppose something is broken?

I would doubt anything is "broken". You may be expecting more than these files can deliver however.Experiment with the position of the sliders in your FS sound dialogue - that may help. Also I get the best results when my engines are off and I am watching (and listening) from spot view (rather than cockpit view) to AI aircraft which are close to my aircraft - i.e. parked next to me.I understand the AI sound options in FSX are considerably improved over what is possible in FS2004 but cannot verify that.Good luck.
