The sounds of space

Welcome to my latest obsession: Sounds from space. I know, I know, space is for all practical purposes a vacuum (unless you're designing an interstellar ramjet) so sound as we know it doesn't exist there. And even if it did in the thin stellar media, we'd need fantastically sensitive microphones to pick up any hint of audio.

Well, I thought so, until I stumbled across the "NASA Space Sounds" video below when it was being shared around the interwebz recently. Instruments aboard Voyagers I and II, as well as several other space probes, recorded an array of electromagnetic signals that, when converted to sound (think of it as running it through a space age amplifier) the result is a strange and eerie ambient sound that is utterly engrossing. To my ear, at least, the pieces are evocative of the non-classical music soundtrack from 201: A Space Odyssey. So that's bonus points right there.

The sequences sampled below are taken from a series of 5 CD put out by Laserlight in 1990 titled "Symphonies of the Planets" as well as an additional volume a few years later titled "Celestial Love Songs." Long out of print, they're quite pricey to purchase second hand. Fortunately, they're readily available as MP3 (as well as other format) downloads online, the only drawback being the file labeling isn't consistent and therefore it's challenging to keep track of individual tracks. And since all data, audio and video released by NASA is public domain, fans of these fascinating ambient sounds may download with a clear conscience that no copyright is being violated.

Alas, in my obsessive research, I've learned that things aren't so cut-and-dried. Yes, NASA does take collected electromagnetic data and convert it into audible sound, but the raw, unvarnished audio doesn't sound all that much like what we hear on the CDs. That's because Laserlight (or Brain/Mind Research, which handled the production) didn't just take the NASA audio and burn it to disc. They ran it through an intergalactic version of the nefarious Auto-Tune, processing it heavily and looping, over-dubbing and sweetening with synthesizers to the point where many of the actual "space sounds" are tenuous at best. In fact, some pieces, such as the samples of "Song of Earth" and "Voices of Earth" in the video above simply do away with the source material entirely and re-orchestrate it. I guess that make it an artistic interpretation of the data rather than an objective representation (which opens up the whole objective/subjective reality can of worms, but I digress...).

What's more, it brings copyright into question. It is clearly established law that what is public domain cannot be subsequently copyrighted (publishers may copyright specific presentations of public domain materials, but not the content itself, which is why you can find free 1920s jazz downloads online, as well as the complete works of Charles Dickens, even though publishers put out new editions every few years). However, derivative works of both copyright and public domain can be copyrighted, but only that which is new and derivative is thus protected, ie the original which is incorporated into the derivation remains in the public domain. In this particular case, I would expect the Brain/Mind Research productions to be fully covered by copyright protection. Being out of print is irrelevant. However (and I'm full of caveats today, aren't I?) their persistent and insistent claims (indeed, the entirety of their marketing and mass appeal) that the audio is direct from NASA, with no claims of alteration on their part would, at least superficially, serve to undermine any copyright protection as, has been pointed out previously, all NASA materials are automatically released to public domain. For Brain/Mind Research to assert their copyright on these works, they would effectively have to admit false advertising, which would significantly diminish the value of said works. It's an interesting academic question, albeit one I doubt anybody is going to bother exploring any time soon.

Authentic or not, I find the interpretations of space sounds interesting and appealing. I'll be keeping an eye on Ebay and the like in case a CD shows up for a bargain price...
