safari does not play ogg files, i'm surprised he/she didn't just upload a wav file.

#4Running it through a FFT, the noise looks similar to blue noise, but with a lowpass at 1000 Hz

#5I've heard this before! In some Nine Inch Nails tracks. I always thought it was white noise + bandpass + clipping or distortion.

#6To me it sounds like the ships background noise in Star Trek.

#7My initial reaction was like "Oh, like white noise!"
I could not have been more wrong. There is very clear structure in Perlin Noise. Great write-up and I learned something.

The article doesn't adjust for the inherent lowpass/highpass/aliasing behavior of function parameter rate vs sample rate, which is responsible for most of the audible difference, especially the similarities to real life low-passed-noise situations (airplane cabin, high building) noted by the author. Still, I agree, you can hear some residual tones!

I haven't read up on perlin noise recently enough to know whether that's inherent to its structure or whether there's a more mundane explanation like distortion or encoding tomfoolery.

Won't play in desktop Safari, either.

#10Didn't really understand how he got to it, but would be interesting to hear this noise source across the larger spectrum (not just the low freqs)
It might sound/be more natural/fractal than pure white noise (+LPF), I can't tell. But it won't work to drown out office chatter because its the high freqs there that matter.
