Not a belt happens not at idle but gets louder as I accelerate. The harder I gas it the louder it gets.

Check to see if something rubbing against flywheel or torque converter bolts loosened up.

For a test, with a cold engine, remove the serpentine belt and see if the noise is still there. A bad idler or tensioner or accessory could be fooling you. Running it for a minute or two without the belt will eliminate that either way.
