I had this same challenge (as will every other basement studio). What I ultimately did was to build framing around the ductwork, so as to effectively exclude it from the room I was building. Then, I stuffed insulation between the framing and the ductwork. I took care to ensure there was no physical contact between the framing and the ductwork as this would provide a nice transmission path for the sound. THen, I sheetrocked over the framing, caulked, put up some RC and sheetrocked again.
Ultimately, you could hear the airflow through the ducts, but it was so minor it wasn't an issue except for soft vocals. In this case, the rest of the house froze or sweltered (depending on the season) until the elusive killer take was finally captured.
THe nice thing about a basement is you rarely need duct openings as the temperature is fairly moderate due to the earth mass.
Good Luck!

yes, but the ducts go perpendicular with the floor joists. I am not a carpenter by any means but is there a way to use plywood with this setup, by cutting nothches in the plywood and directly attatching the plywood to the floor joists(see pic). How would the plywood attatch to the floor joist this way - by toenailing (like I said I'm not a carpenter).
Or would it be better to use 2x4's to create the frame?

Searching for the sound
Frame it. 2x3's are ok, cover it with the ply, resilient channel and sheetrock. When you cover over the rest of the ceiling seal it where it meets the duct chase.

Cheetah,
Just put a 2X4 perpendicular to the joists and parallel to the duct. That'll serve as the framing top plate. Unless of course you are going for some totally independent room within-but-not-touching a room. Then you may need to resort to some plywood thingie.
Given that the ducts will be your biggest source of noise incurssion (and delivery to the rest of the house), it's probably more important to keep it out of the audiosphere than it is to craft some independent room-in-a-room scheme.
It worked for me, although not completely quiet.

I agree with Tod and others - put a frame up. One thing I noticed was the plumbing outlet coming in from the left of the first picture. It is very old plumbing material used there, why not get a plumber to advise as to whether it can be cleaned up using newer Poly pipes??
