Assuming a typical support post of four or five inch diameter, and hollow, it won't affect the acoustics of the room, but it MAY "ring" enough to bother you while recording or listening, depending on the situation and the tone being played. My guess is that it will only be a problem in very specific musical situations, at which time you'll say "why didn't I wrap that stinkin' post!".
Rap on it with your fisted knuckles and listen. Hit a tom-tom and listen. Try a range of frequencies on a trombone and a trumpet. If the ringing is louder than you can accept, just wrap it tightly with some foam insulation and duct tape. For a more pleasing appearance, do like Ethan said and wrap some fabric around it. Maybe colored duct tape. ;)

I had a similar problem in my home theater/listening room. The post was right in the middle of a 12'X17' room. Not very good for movie viewing. The post was supporting one of the main beams on the ceiling of the basement. I consulted an expert and he advised me to just take it off and move it in the wall I was constructing, in the 12' width. So there is about 12 feet of beam without a post. The beam is made of 6 2X10" and is very dry, so it won't budge.
Hope this helps...

one nice idea is to wrap it in hemp rope glue the post and wind the rope around it start at the bottom and go up.You can use a thick rope 1 inch should be good .I have the same proplem and that is what I am going to do . My room 16.5 X 23 X 8.3 the drywall is just being taped as I write this 10 inch's of insulation in the ceiling covered in a fabric of some sort. My post is also next to where My chair will be oh well.

Thanks for the ideas and advice. I was definitely planning on wrapping the post in some way, if for no other reason than to make it look better (I do want the room to be as aesthetically pleasing as possible). A tight layer of insulation followed by some kind of fabric that will blend into the decor seems to make sense (I'll skip the duct tape though, despite the lovely rainbow of colors that's available!).
