Default Engine clicking/ticking noise...PLEASE HELP!!

2003 Corvette Z06 150k miles (stock)

Hey guys! I have had a slight ticking noise from the engine for about a year now only at idle that was BARELY audible only outside of the car or with the windows down if you really listen for it. Well, out of the blue while I was sitting in a drive though I start hearing it from inside the car so I lowered the windows and notice it got much louder. It ticks faster as rpms rise but disappears at around 2000rpm. I was thinking timing chain related but the service was done at 101k and I'm at 150k right now. I started looking on youtube to see if there were videos of similar noises and found one that is EXACTLY like it. Anyone know this guy or have seen this video posted here? I'm sure we have the same problem and I gotta know what it is so I could sleep at night.
Any help, info, advice greatly appreciated!

I had a tick for a while... turned out to be a loose spark plug creating an exhaust leak... Worth a shot! Good luck!

This sound is related to one of your rotating assemblies... alternator, AC, tensioner...etc. You need to get under the hood and listen. You will figure it our pretty quickly.

Not that I saw.
OP, get the hood open. Listen around. Maybe a slight exhaust leak? AIR system?... Maybe post a video.
