Strange title i know.
Just something concerning the Tuned cars.
Does anyone know what exhausts are applied to the cars?
You know, what stage?
Also, are the various stages in exhaust upgrades reflective of real life, or is the stock exhaust notes recorded then manipulated to achieve the desired effect for the upgraded components?
 
Nope, how could anyone know when we don't even know what choice of exhausts will be in GT5 and what each choices effect on the car will be.
 
The point i was trying to make is, if the sound of the exhaust upgrades are computer generated or actual stages of real life applications.
You don't have to know what will be included in the final game because the tuned cars already posses an exhaust upgrade easily identified from it's normal counterpart.

Oh right, now I get you. The sound changes are all worked out by computer. PD don't physically mod real life versions of the cars and record them, that would take decades for them to do and far more money than they would ever make back on game sales.

So in short, it's computer generated, as it is in every game that invloves modding your cars.

On GT-TV the special about the GT-R showed them recording the exhaust sound of the GT-R for GT5-P so that it sounded authentic...maybe they just did the GT-R for Prologue?

They did this for a baseline. I believe they do this for all the car's so the computer can adjust the sound for the turned version.

You missunderstand me, they do record the cars, but they don't record the cars for each stage of tune seperately. They record the car in standard trim then they use a computer program to work out how the engine note should change under when the varios modifications are made to the car. The cars are recorded but only in stock trim, when the engine note changes due to modifications, that is the original recording being manipulated by the computer not a seperate recording of a tuned version of the car.
 
Going by older GT games, we don't get stages, there is Sports Exhaust, Semi-Racing, and Racing Exhaust. It could be any one of those, but no way would you make the 7.0L LS7 sound like what it does in the Tuned Corvette. Their exhaust sounds (the upgraded exhausts) have always been messed up. You get V8s in GT games sounding like 4 cylinder engines.

I agree.
So, we can expect the same again for GT5?
I mean the Ford GT 'Tuned' sounds different than the stock one but in saying that, it doesn't sound like a V8!
I'm pretty sure Forza actually finds cars that are tuned in various stages and records them as is.
Just listen to the difference in enhancements and you'll notice that they don't sound 'computer generated' but rather realistic.
 
the word "stage" can be very car spisific, they use that termonology on my WRX but if i went to a fellow mustang guy and said "hey man I got stage 3 exhaust on my stang , what you got" I'd probably get slapped... So I dont know if that could apply to GT?

I'm referring to 'stage' as just a generic term in regards to upgrades. I mean if i went to a performance specialist and asked for a stage two/three exhaust, he'll give me a weird look and say, "Too much video games mate".

No, Turn10 do not record the cars stock and then in the varying stages of tune, the Forza 2 sepcial edition book has a chapeter that deals with the sound and the complexity of getting it right and it touches on getting the mixing balance right. Turn10 do a good job with the engine noises, that's true but it's not because they record the cars tuned, it's just because they do them well. The formula used to alter the engine noises is what will determine how the engine sounds and the range of sounds included in the engine noise.

Turn10 recorded a lot of the engine sounds seperately ie the transmission noise, the induction noise, the exhaust noise, recording all the sounds seperately then putting them together and manipulating each one independantly of the other, when done right gives great results. It allows you to hear the intricacies of the different noises a bit more. That doesn't mean that they record the sounds of the tuned cars, that just means they use a different formula to calculate changes in note and perhaps recorded the origninal sounds in the different way. You say that Forza's noises don't sound computer generated, well how would you know, a computer generated sound can sound more realistic than an actual recording, depending on the quality of the recording. There's nothing to stop a computer from working out changes in note accurately if the formula is done right. But you also have to remember, the more work you put into the sounds, the more resources your taking off the computer.

Thanks for clearing it up.
So it ultimately boils down to the sound engineers and their competence.
How does the program deduce whether the sound is from a sports,semi,racing exhaust?
Because judging from certain cars, PD's formula is quite off the mark.
 
I agree, some of the sounds in past GT games at least have been well of the mark. I've never heared a racing exhaust produce some of the sounds they have on certain games.

What the game will do is lets say the orginal sample is called sample A, the stock car will play sample A and as you increase the revs the computer will raise the pace and pitch of that sample to indicate a change in revs. Then you combine sample A with par 1 (part 1 being the sports examust), the computer will then increase pitch and power by say 10% across all the revs you use. Then it will alter thoes even more with the next part so on. That is a very, very basic idea of what is done. You have more variable than just the pace, pitch and power, you can alter things like the bass and echo of the note and so on. The problem I find with a lot of PD's sounds when you fit racing exhausts in past GT games is they lack power, they sometime get the pitch right, not always, but sometimes but they sound weak and tinney. Forza get's a good sense of power in their sounds.

Making the computer recognise how to alter the sounds is just a case of assigning a different variable to each part that become part of the formula for the sounds. So Sound A + Part 1 = Pace +10%; Pitch + 1-%; Bass + 5% etc. That's not a real formula, I don't know what codes PD or Turn10 use, and it is much more complex than that and there's far more variables than what I'm going into, but hopefully it goes some way to giving you a rough idea of the process.
 
I must admit, although still not the best, if the Tuned cars are any indication, along with the standard ones too actually, the sounds are still better than GT4.

I think the stock GT sounds better than the GTLM, and has the best sound in GT5P. To me it sounds very close to a NASCAR car when watching races via home theater sound.
