It's related to engine speed (revs), not car speed. Sounds like a feathering dull noise. Possibly compressed air leak? Might not go on long drives till it's been to the garage.

Hard to diagnose without hearing it.

Since it's related to RPM possibly exhaust leak.

Is it still running smooth going Ok?

Make a recording of the sound and post it.

I wouldn't go to a dealer they rip you off.

Find a mechanic that is busy with cars lined up to be fixed.

If they have no work waiting they will find things that don't really need doing so they can charge you more.

I would start looking at exhaust manifold gaskets exhaust temps are over 500 deg c . Then move down down exhaust system. Just a guess we will see if i was close.

Could be exhaust leak too, thanks. Runs well still, idling was a bit unstable.
Sort of a whirring feathery noise, possibly disappears about 2000 +rpm. Perhaps a pump or some pulley , had a tensioner pulley changed a few years ago. that should be ok, serpentine belt looks good.
Gave it an oil and filter change yesterday. Coolant is good. Idling seems better now.
I take good car of my old cars, I'm pretty fussy about old cars NOT breaking down

Could be alternator bearing or brushes, less likely but possibly water pump. Grab your biggest screwdriver and use it as a stethoscope, put the handle to your ear and touch various engine parts and see if you can isolate where the noise is coming from. FFS don't get the screwdriver into moving parts.

You do have vacuum for various functions such as climate control etc. They are small diameter rigid "hoses".
Get a can of spray carburetor cleaner. Yea, you don't have a carb, but find a spray can at your favorite parts store. Start the engine and spray it near the hoses. When the engine speeds up, you have found your leak. You can buy new "hose" (Toyota will probably have exact replacements, for an awesome price) or depending on the break, electrical tape may solve the issue.

Very well diagnosed. You are right. I had a good look over the air inlet side (I'm not a mechanic at all).
Saw a couple of worm drive clamps holding 2 areas. Took a #3 phillips screwdriver, one tightened up about 1 1/2 revolutions. That is a lot, the other less than a full revolution, that is a significant.
Idle speed is stable now, it's not sucking air in where it should not.

Congrats

Oh well, he has a 2008 Camry - he can't go wrong.

From about 2005 to 2009, those are the most reliable cars in the country.

He doesn't give a lot to go on though. Auto/manual? Noise with clutch depressed? Where the noise is coming from even in a general direction. Very hard to say what it can be so I assumed automatic for simplicity's sake..

A vacum hose leak will cause engine to run rougher it will interfere with manifold pressure sensor. Idle will be all over the place yet this can happen with high KMs as Idle Air Controller valve carbons up which doesn't allow it to work properly.

A vacum leak will be really noticeable at idle and small throttle openings when vacum is higher. At full throttle a vacum hose leak doesn't make much if any difference.
It's not something you will hear unless bonnet is open and you're searching for it.

Vacum is highest with 0% throttle opening.

That said all rubber hoses have finite life after about 15 years they can be questionable.

I had a radiator hose split once coolant pissing out i used electrical tape wrapped around it like a tight bandage to get home after topping water up. With older cars probably wise to keep a roll of electrical tape in it.

With high kms it could be worn bearing in alternator or water pump as setanta suggested.
