You tube - schmu tube - post a link.

Oh by the way another poster's suggestion of searching for the noise with a
bit of tube (or even a stethoscope) was something I was going to suggest.

Most likely it is an accessory, so if you take the belts off one at a time
you might narrow it down.

Candidates may include

water pump
oil pump
alternator
AC
fan (if it has thermal slip)
power steering pump (checked the fluid lately? - it will make a din if it
runs out)
internal engine noise (e.g. camshaft bearings)
