////The output sound is not the sound of the planet, josep. Come on. It is a mathematical translation of frequencies from one part of the spectrum into sound frequencies. Do you seriously think planets suspended in vacuum make noise? Or do you think these sounds were recorded in the barely perceptible thin atmospheres of some planets, and yet somehow made sounds that are similar to Terran noise?

Put your thinking cap on, dude.////

Well, thanks, for that explanation, Amos. Heavens to Betsy, I thought you just opened a window on the shuttlecraft and stuck your cellphone out into space and recorded the earth whooshing around in a vacuum. Silly me.
