YouTuber crysknife007 has isolated the ambient engine hum of the Starship Enterprise as heard in Star Trek: The Next Generation. The sound is looped repeatedly into a 24 hour long YouTube movie.
One of my favorite things about the Star Trek franchise are all the great ambient sounds that represent the engine noise on the various ships. My favorite ambient noise from the whole series is the engine idling noise in TNG. I have cleaned up a sample from the show and then looped it for 24 hours. Great for ambiance and imagining that you’re in deep space.
