Who else has the GNP sound effects CD? It's pretty neat. It's easy not to consciously realize how much the sound effects add to Star Trek. The feeling you get, that the Transporter room, Engineering, or a planet surface is a real place with its own unique qualities comes largely from the subtle background sounds. And the Bridge goes without saying. The Fantasy Worlds of Irwin Allen CD set also includes a sound effects library. Fun stuff.
Yes, I ordered that when I was making an animated fan film. It really helped, along with authentic music scores and voice clips from episodes.
