this is not a questios... its a bug report....
when you are going realy fast....
i cant remember the word (in spanish is refubo or succión)
you stay behind of any car... and the car in front of you cut the air....

the bug is...
when you try to overtake that car... you move to left or right...
you start to hear the air again when a half of your car stay out of the air free...
but is too brutal the change like... 0 to 1... and not 0.0 0.1 0.2 0.3 0.4 untill your car is out of this zone.....
if the sound change like this...
the phisics of this are the same...
so...
One can be up to the half out of this zone and to have the same resistance of the air, which is nothing
 
The zone of lower air pressure (called "draft" or "slipstream") diverges from the back of the car ahead - it isn't just a straight line behind it.

In any case, the noise does increase in small increments - it's just hard to hear it on a TV.
 
i did it with a toyota minolta 88c-v at 375 km/h
to make it more extremely....
in last strait in nurburgring to have enought time to go in and out...
and the change is like that...
i use headphones with all volume... no music... and go at low rpm....
 
I use 1000W monitor speakers.

If you move gradually out of the slipstream you will hear a gradual change (try the Honda Odyssey Mission Hall race). If you move suddenly then you will hear a sudden change.

That makes sense Famine:tup:

As you move slowly out from the car in front more of your car will be exposed to the air pressure again and the sound will get louder.

If your using bumper cam this is an annoying thing but you will just have to live with it im afraid:indiff:

Would have been a nice option to spec bumper cam view with rear view sound....that would have been good!

The sound does change gradually, if you move REALLY slowly, then you will hear the change, and the air resistance will also increase gradually, not all of a sudden. If you are drafting a car, you should notice that the car gains speed more quickly as you get closer to the car, due to less air resistance.

i allways use the bumper cam...
is just stupid use a copter cam with a cockpit....

I used bumper cam for a long time, but I started using the outside one after I got bored of watching the replays just to see my car in action. (I like to see my car drifting.)

I still use bumper cam for time attacks though, I am better that way.

if you use the bumper car for a long time you star to know the dimensions of the car and make easyer the drivin... in snake corners...
later see it in another cam.. shows how extreme you drive... (more in drift...)
 
Famine
I use 'Copter Cam.



but...
you use copter cam allways or like PERFECT BALANCE????
if you use allways... try to use a bumper cam...
in real live there is no copter cam....
i know this is a simulator...
but i try to make it the most real possible...

Not always, the front of the car yes, but while drifting I frequently ended up going out of the track, because I couldnt tell where the back of my car was. It helps a lot when grip driving, but for drift you need to be aware of the whole car 's position the track.
 
try this...
in clubman stage 5....
in the s turns...
stop the car...
go reverse untill the back part touch the side of track...
if you have a dfp look to left or right and imaginate a line... (when the bumper cam is...
move back and the distance betwen the line and the wall is the distance of the car...
or... when you are drifting... when you touch the piano or the grass...
create the same line... and thats will create a limit while drifting...
is just practice...

It may be a stupid question, but why didn't you post this in your other thread? :odd:

cuz we start talking about the wind an finnish with something else
look the other...
how it start and how it end...
 
Ok ... but you could have brought it back to the original topic with your new question. And as I'm just taking this thread offtopic, you'd have to open another one. Nevermind, I'll shut up now! :O

All the time.

Catch me - if you can... :D

this is not a question... read the top...
it was a bug report...
but i have new info to try ...

FAMINE:
If you move gradually out of the slipstream you will hear a gradual change (try the Honda Odyssey Mission Hall race). If you move suddenly then you will hear a sudden change.
 
if we are on the subject of which camera we use i use either bumper or the one where u can actully see the car. the cars always sound best. buuuuuut around the nurburgring i tend to use the bumber cam becasue that way i can see where im going.

[edit]

well ok that was off topic as i now see. well ok erm ill shut up aswell
 
I don't know what event that is, but I'm pretty sure it's not an Audi R8 as named on the page. (The R8 has paddle shifting, not a shift lever, and I can't be sure, but that cowl looks too pronounced. Also, the right-hand mirror on the R8 is not on the cowl, but further to the side of the car. And the R8 is turbocharged, which this car is not. Nit-picky, and irrelevant to the thread, I know.)

I do like the fact that the shows the wind noise drowning out the engine noise. (This doesn't happen on F1 broadcasts because the mikes are intentionally placed where the wind won't reach them. This video was recorded with the camcorder's built-in microphone, facing right into the wind.)

I don't understand karras85's obsession with calling this realistic feature a bug. You go fast, you get wind noise. You ride in another car's slipstream, you have no wind noise. It's realistic. Karras85, take a ride in a small aircraft someday, and while in the air at cruising speed, remove your headset. Then you'll understand wind noise.

one by one the answers....
i dont care if is an r8 or not... but im talking about wind incrase and decrase while overtaking.... that car is alone... so... :crazy:

when i put the f1 example (another topic first part...) but.. im talking about a steady camera in the track not in the car... (is ovbiously the cockpit camera have the mic to hear the engine only... cuz is inside the cok..

yes... its an obsesion to reach "the drive of your life" as opening says..
i see you didnt see what i am talking about....
im talking about.... when you are in a slip stream.... if a half of the car stay in slip stream... you cant hear anything ( it suppose to hear some wind)
but you pass the half of the car and you hear all....
im talking about that brutal change....

if we play this game... is because is the simulator much closer to the real driving and the list of cars and tracks... with the correct tools you can learn some driving techniques... or just for fun....

as players of this game i think we have a responsability to make a better game...
we know the good things this game have....
and we coult tell the mistakes, bugs or whatever you call it to fix it...

and... we are talking about cars... not planes... this is not a flight simulator page...
as Boundary Layer says "you're comparing apples and oranges"

i almost forgot...
i tried the the "Honda Odyssey Mission Hall races"
is the same thing... to hear nothing to hear all...
 
Karras85, I do understand your point about moving out of the slipstream. My point is that it is an abrupt change in real life, just as it is in the game. The pocket of air behind a car, truck, or whatever is pretty much a well-defined zone, with a very narrow but turbulent boundary to the outside air. You move across that boundary, you get wind. Now. Not gradually. There's a line, not an adjustment zone, and that line will be outside the leading vehicle for a bit, narrowing as you get further back, but close enough, you can be slightly out of line (not directly behind the lead car) and still be in the slipstream.

My comment with the aircraft may have been better directed at your other thread, where you seemed to be saying you think the wind noise is too loud. It was meant to show that wind noise is loud, whether it's a car, boat or plane. Planes are lots faster, so it would be an extreme example. Wasn't meant to be sarcastic.

However, and this is in the game, as you gain on the car in front of you, entering the slipstream from behind rather than from the side, the wind noise does fade gradually as you go through the region behind the car where its wake is mixing back with surrounding air. At the same time, your car experiences a bit better acceleration as its aero drag decreases.

None of this says that the effect might not be exaggerated in the game. Maybe it is, but apparently not enough to bother anybody else. The consensus of the thread seems to be that the effect is realistic. My own experience in real life is limited to about 145 miles per hour, and I try to avoid traffic situations at that speed. My real life experience with slipstreaming is limited to about 80 or 90 miles per hour, a speed which hardly raises a ruckus at all in GT4. Therefore, I can't compare any real life situation to say, Mission 23 and the 170 mile-per-hour slipstreaming. I can't know know for sure, obviously, but I suspect the case is the same for you.
 
karras85- The next time you are a passenger in a car going fast:

1) Open the window and stick one open hand out so that the fingers are pointed out and the blade of the hand is perpendicular to the road.
2) Put your other hand behind it, move it up and down.

You will notice a sudden change of pressure on the hand closest to the rear of the car. This is(on a smaller scale of course) basically what happens when you pop out of the slipstream.
 
do different car have different wind noise loudness ? like:
louder in rally car
loudest in F1
unheard in racecar (engine noise too loud)
silent in aston martin
