Whining sound - Help! *VID*

There's an annoying whining coming from my '99 M3. The pitch gets higher as I press on the accelerator. I am including a video so you can get a better idea of what I'm trying to describe. Sorry, it was filmed at night, but seeing the car isn't important, just listen. All help is greatly appreciated. Thanks!

you need belts and pulleys.. possibly a tensioner or 2

not a big deal. order 2 belts, 3 idlers and prepare for the fact that you may need tensioners.
