Is she dying? Definitely does not sound good. (Video Inside)
Ok, I posted a while ago about the same issue, however, the sound has gotten worse. I have no idea where this is coming from, I can't tell. I can tell you that while listening the exhaust at the back, I could hear it from the exhaust too.
Here is the video, You can clearly hear it towards the end of the video. At the beginning it is kind of noisy.

I was researching the VQ engine and your engine sounds like it needs valvetrain / head work on it.
Here are some video's from teh VQ35DE engine V6 and should help with diagnosing the sounds.

Rocker arm damage or something of that sort

Urgent Help need valvetrain chatter and tapping...Maybe TDI?? - G35Driver

Re: Is she dying? Definitely does not sound good. (Video Inside)
thank you guys. I forgot to mention, as soos as i give it gas (even barely) sound goes away. She becomes smooth. No knocking, etc. While driving. No hesitation. Driveability is smooth as usual. She has 55k on her now.
Do you guys think winters brutual cold weather caused this? This happened in the middle of winter. I suspected that, my gf drove her while the engine was ice cold, went kept the rpms a bit high. What do you think?

I get the same sound if my CIA comes loose and touches the Serpentine belt.
The fact that he has no loss of drivability suggests something simple. Outside the engine.

I would also place my bet on a bad bearing, or loose pulley. The high frequency of chatter makes me think that its something spinning faster then the engines regular 600rpm idle. You can hear the normal valve click in the background about 3-4 clicks a second. And the loud grinding noise is much more frequent then that.

If you don't have an engine stethoscope here is a trick used by technicians. You take a long 3/8" extention, as long as you can get. I have a 3' extension. Put one end actually resting in your ear and place the other end around the engine listening for the point the noise is the loudest. You may not pinpoint the exact problem but it puts you in the area to investigate.
Hope this helps. Let us know what you find.
