You need to get the engine scanned so that you know what the SES lamp is complaining about, as it will give you a starting point on working on the problem.
It is hard to diagnose an engine problem by recorded noise, to me yours sounds like a slipping belt or a bad roller lifter with a frozen roller, but it is just a guess. As others mentioned, remove the belt and run the engine and note if the noise goes away.
Many times when there is a ticking noise when engine is first started, and then goes away it is caused by a worn or sticky lifter that has lost its oil prime. After running a while the lifter fills up with oil and the noise goes away, but eventually it will continue as the problem increases with mileage. A lighter viscosity synthetic oil, such as 5w30 may help if it is just a dirty sticky lifter.

noise
Well ive had this camaro for almost 2 months now 85,000 miles on it when i got it. 2002 camaro v6. Very clean. well it started making a noise like a couple weeks ago and it sounds horrible. Check engine light has been on but its because u got some gas with alot of water in it like a week ago and i have a vacuum leak. (i think) i dont know much about cars but its been cold in my part of alabama. the noise starts when first started then shuts off after like 40s or so. if i accelerate while its making the noise it makes it during acceleration. i decided to see if its the cold weather but today its 60 outside and i gave it a start and recorded it and i still got the noise. What could it be? (EXCUSE MY GRAMMER/TYPING, just trying to get answers) PLEASE HELP. Link to noise on youtube.Recorded with my phone so excuse quality
