My house has cedar wood lap siding which looks good but the north side takes some pretty rough weather. I don't want to repaint again and wonder if it would it be OK to put either vinyl or metal siding over it? I'm thinking it might act as sound barrier if I kept the old siding on but I'd probably have to put on a plywood sheathing first for it to be a smooth surface. Can you tell me if this idea is practical or economical?

Vinyl siding can be installed over top of wood clapboard siding and doing so would be the most economical way to get the home resided. New plywood sheathing would not be necessary. A skilled siding contractor can install the vinyl over top of an uneven clapboard surface. The only type of siding I do not recommend be covered is Cement Asbestos shingles. In that case, covering the siding means nailing through and crushing the asbestos shingles which can release it into the air and potentially end up as a big toxic mess for any future homeowner that needs to replace or even repair the vinyl siding.
The only down side to putting vinyl over wood is that since the siding is about an inch or so thick, areas around windows and doors may appear recessed behind the "J" channel that would be used as trim. That being said, it is still not worth the cost of stripping off the old siding.
As to your question about sound proofing, adding the siding will not significantly reduce sound transmission so that should not be a part of your consideration.
