(This is not a mod or a hack lol, I used movie maker to add the sounds)
So basically, here's a few ideas to improve the audio in Star Trek Online such as adding voice dialogue and Star Trek Movie Soundtracks. I also enhanced some of the weapons, explosions, opening doors, and ambient sounds. I even added sounds from the 2009 Star Trek movie and bridge commander. I know that the sounds from Bridge Commander should not be exactly in STO, but I'm simply using them to illustrate this idea. I tried really hard timing the music and sounds just right, to make it look as if was really part of the game hehe ^_^.
I have to admit that the original FX sounds and music do sound really awesome =)
Again, sorry for the crappy quality of my video =p
