Hi folks, thank you very much for helping me out.

I believe the squeaky noise is from belt, but I am not sure. I post the ticking/chirping noise here:
https://www.youtube.com/watch?v=i5w0VwxOxQg

it's Honda civic 2002, first time owner, 98k miles. no parts change under
hood.

yesterday I notice the AC doesn't function well, seems like doesn't work.
Besides that, everything work fine.

today it's 75 degree. I drove 30 miles on highway, turn on maximum AC even
though there is no cold air coming out. I notice it's hard to drive beyond
60mph, and maximum I can reach to is 70 mph. I also notice the "woooo" noise from under hood. I thought it's strange, but didn't pay much attention.

I got to local doing some shopping, 15 minutes late, I start the engine(didn't give it some gas ) . I
heard this roaring noise which scare me, I never heard this kind of noise before. i hurry back home. On the way back,I turn off AC, the noise apparently reduce a lot but still there, and I can also drive to
80mph easily.

Once I got home, I let engine idle, and record this video. the noise is not
roaring but still noticeable. It seem to be under the running belt, or under the
engine. is it something related to AC compressor, drive belt...?

I checked the engine oil, it looks normal. no engine light on...

Any thoughts?

Thank you very much for helping me out!

The AC compressor belt is driven by the crankshaft pulley so if the compressor isn't turning right the engine will have to work harder. The difficult acceleration and the roar starting it up are the engine having a hard time turning it. Since the AC isn't working as well it definitely sounds like the compressor is your problem.
