I want to create a sound for a scene, in which the camera closely travels along a big planet and the planet is spinning in its own orbit slowly.
What would you suggest for this situation? Any references and EQ tricks are also appereciated.
Since space is a vacuum, technically there would be no sound at all. Of course we all fall victim to the cliché that things that aren't supposed to emit sound often end up doing so in films/video games/tv shows, like computer graphics and laser guns. But I really do appreciate when sound folks make bold statements like not putting sounds in for things like planets turning, spaceship bys, explos in space, etc. Try it and see how it is received. One television series, Firefly, achieved this with great success.
For a quick fix I'd start off with an earthquake rumble or similar subby sound to lend it weight, maybe even layer a few together or pitch one up or down a few different ways so you can modulate the sound slightly as it turns. If you're fortunate enough that it has a discernible or extreme climate then add arctic wind/fire fx as appropriate. I also used flame throwers recently for texture on a fiery planet sequence and it worked quite well
have the ripples in gravity wreck the music instead of producing sound on its own? :D
Like most of the others, I think it really depends on POV (angle, distance) as well as what state the planet is in.
That said, I really liked what Ben Burtt did in the opening scene on Star Trek (2009): http://designingsound.org/2009/09/ben-burtt-special-star-trek-2009/
