Here's the link to listen to it-

I hear it almost every time I start driving the car even if the engine is relatively warm. The sound follows the rpms, so when the rpms are low the whistling sound is slower and lower pitched and when the rpms climb higher the sound becomes higher pitched and whistles faster. The sound is coming from the passenger side of the engine somewhere near the back of the engine closer to the firewall.
I'll hear the sound usually for 4 or 5 minutes after starting up the car. I hear it when I am in gear and at low rpms. As the rpms climb to about 2000 the sound will dissapear. Then I'll shift at 2500 or so and I'll hear the sound again in the new gear as the rpms move up until I get to 2000 rpms again and it dissapears again. I hear it at idle sometimes also, soon after starting up the car (like in the video).
What could it be?

It's really hard to tell with the video provided, but for starters,
If it's a manual shift, the way you describe to noise, might be inclined to look at the throwout bearing at the clutch.
Also don't rule out the alternater bearings, and the belt tensioner.
I don't know the history of the car, nor the past work on the exhaust system, as a small leak in this area will often produce such a sound, or similar.
Also, is this a front wheel drive? More information can be had by direct e-mail.

Aluminum Valve cover engined Maximas were the real runners of there time. Does your engine make the same noise with the cam timing solenoids unplugged or when you disconnect the back one the rattle gos away? See each camshaft has a $1000 sprocket on it if the oil supply to the sprocket fails the camshaft rattles. I have heard it describes as lifter noise. And thank you for real evidence. Chances are variable camshaft timing solenoid may fix that rattle. If the heck has been run out of the motor you might also need a sprocket.
