Okay, I was going to make a pass on all of the unit responses but as it turns out Audition's script recording is really awful and it just goes LOL SCRIPT STOPPED when I try to make a batch file with it. Also, the noise reduction has something against these sounds and doesn't want to completely remove the fuzz.
But whatever.
I removed fuzz from three particularly notable engine sounds. You can still kind of hear it a little bit but not nearly as much - any deeper of a reduction and the engine would get distorted. Did some EQ magic on several weapons. The difference may not be wholly noticable if you listen to them on their own, but I assure that it is there. Listen to them side-by-side, especially the Romulan torpedo. It is a different sound, though. I tried to avoid making them sound too different, just adding more depth (they were "flat" and had little upper-end fidelity). Also, since I removed some sound, I could also cut off/rebuild tails on the reverb and this reduced the length of the audio. Shorter files means more can play faster because they don't chew through sound channels. Though the difference is minimal, I got into the habit of doing that in Starcraft which is limited to 8 channels for everything.

This is just the edited sounds. Use in combination with my fixed sound pack for great justice.
