tpark103, I think the same thing.
For example:
I was particularly SHOCKED when I heard the Chevrolet Corvette Z06 (C6) '06 in real life. It's the EXACT SAME sound.
I don't really know if he modified the car or it's just the crappy sound quality of youtube, but in my HT sounds A LOT (and I mean A LOT) more clear and robust as you may expect from a HT.
There are indeed a lots of cars that has a great sound, but they lack, in the interior view, other types of noises.
Griffith500, thanks for asking that, I was going to ask the same thing.
And mikecustom, let me ask you something:
What type of Home Theater do you use? Which ones are your settings? Do you play the game with what range of volume? Do you tweak the sound or do you use the sound purely from the game without any changes? What setting do you used so far in the GT5 Sound Menu?
I DO know that the sound in-game is not the best, but at least is an effort to be realistic, but let me explain this:
As I said in previous comments, we all know that the engine sound isn't the best one in various cars.
Well, my point of view, and you can disagree with me without a problem, is that the engine sound straight from factory is pretty damn close to the real ones.
When you start to modify the car with turbos and tailpipes the sound goes bad in some cases (terribly bad in some cases), pretty good in others.
I heard a pretty exciting sound yesterday in a DTM, and I'm going to hear that thing again today.
Every single time I listen to people complaining about it SO much, I start to think about it too, and I came always with the same, the sound isn't perfect, but is a game. It's better to enjoy the game, if you can, or then you can quit and play other sim. I think is as simple as that.
Off course that there are other games with better sounds, but almost every single game I played offers me the same exagerated sound from the cars.
But again, that's my point of view
You can enjoy that in race cars for example (even I did) and then complaining about the sounds of the race cars in GT, but for me, the sounds of street and some race cars at least in a HT, are pretty good.
Not the best ones, but very accurate when the car is straight from factory.
