Interesting thread.
I'm trying to keep my 03 Vivid Yellow P5 alive as long as I can.
Number 4 cylinder has low compression so I'm only managing 18-19 MPG in mixed driving.
Anyway, I believe you said your car is a manual.
I listened to the sound bite as best I could on my PC speakers at work. It sounds more like a grinding noise than a knock.
The first easy thing to do is start the car and push in the clutch to see if the sound goes away.
After that, I would pop off the belt and see if the sound stops. It could be the power steering pump, alternator or A/C compressor. I can't remember if we have belt tensioners or not...been awhile since I had a look under the hood.
Heck, could be a loose clamp rattling against something.
