Sorry for the blatant commercialism, but I thought some here might be interested;
I've releasing some of my sound effects as royalty free collections on my website http://sfx.TakomaMedia.com
So far I've released a collection of machine guns, a collection of whooshes stingers & hits and a collection of antique camera sounds. I have a bunch of other collections in the works. If anyone has anything specific that they would like to see, I'll see what I can do.
