This is very similar to what I mentioned here... Only I remember it being more boops and bleeps, but that may have just been disc 1.

More info on the CDs.

What causes all the radio signals from gas giants?


Due to the immense pressure of gravity, atoms bounce around and knock into each other and cause bursts of energy to be released in the form of photons. The energy in question can lie anywhere along the spectroscopic band depending on the frequency in which the wave is generated; visible light, gamma, microwave, radio, etc. In this case, it's radio.


How are they translated from radio into sound? Is it kind of an arbitrary sampling where they pick a range?


I'm going to assume that if you take the energy wave or "signature" and transpose it higher up on the band, to the realm of audible sound (by pushing that wave through a medium of air, rather than radio waves through the vacuum of space), you get the sound. The CD's I have really don't give an adequate explanation as to how they create the sound, but I have to assume it's the same principle which powers radio on Earth; the energy wave is broadcast out, and receivers/speakers translate the signal to a different medium.

I tried sifting the vimeo version too and found out it was already here.
