Alien speech analysis, page 1

Just thought I'd ask the ATS collective, what peoples thought are regarding the following two videos.

First video examines speech patterns found in a radio signal from the Cassini spacecraft:

The Cassini spacecraft began detecting these radio emissions in April 2002, when Cassini was 374 million kilometers (234 million miles) from the planet, using the Cassini radio and plasma wave science instrument. The radio and plasma wave instrument has now provided the first high resolution observations of these emissions, showing an amazing array of variations in frequency and time. The complex radio spectrum with rising and falling tones, is very similar to Earth's auroral radio emissions. These structures indicate that there are numerous small radio sources moving along magnetic field lines threading the auroral region.

On my web travels, i came across this spectral editing software:

...spectrogram editing and synthesis capabilities, making use of unique spectrograph, synthesis and filtering algorithms developed specifically to achieve the best results possible. Photosounder turns sound processing problems into image processing challenges, and brings the power and flexibility of familiar image processing tools to the creation and transformation of sounds.

On the website, they have this interesting video, where fractals and photographs are turned into sounds.

Do you notice the similarity???????

Do ET's communicate by using EM radiation as pictures? Perhaps there is more efficient transmission of information if electromagnetic radiation (or sound waves), are recorded or mapped as the spectrum of pictures?

Fuzzy logic, but i'm just thinking aloud. I'd love the thoughts of anyone more technically inclined.

Edit: The fractals seem to be the most interesting picture sound patterns, so perhaps interlacing images that follow the Golden Ratio, means more info can be communicated by layering fractal patterns.

I wonder what these would look like if the sounds from the first vid were actually turned into pictures? Wonder if that is possible...

Perhaps it would be this

Sound can be thought of as a side effect of the compression of atoms (a mechanical wave, vibration) and therefore won't travel in a vacuum (space). The sounds you hear are the transduction of electromagnetic waves from a source into mechanical waves using fractal scaling. It's a facsimile.

Think of it this way... You hear sounds from your speaker because it pushes all the atoms in between (air, the medium) which reaches and vibrates receptors in your ear, which is transduced again into an electrical signal that your brain can interpret. You couldn't hear anything if you took the wire out of the back of your speaker and stuck it in your ear!

And those EM frequencies are far too high to be transduced into sound waves directly (far far far above ultrasound even) and so a scaling method is used to drop the octaves so we can actually hear it out of the speakers (between roughly 50Hz - 28kHz). Lots of processing, but pretty damned cool!

If my math is right, if a constant 30mHz frequency is dropped down 11 'octaves' and transduced into sound waves, you would hear it as a ~14,648.4 Hz sound (30,000,000/2^11).

Good question heyo...

Sound does indeed need air. When a noise is made it does two things; it causes compression and rarefaction of the air molecules. Think of a slinky - if you tap it one end, a longitudinal wave 'pulses' down the coil as the energy from one coil hits its neighbour. Eventually, the pulse is received at the other end. This is why sound travels well in water, because the molecules are more closely packed than compared to air, so attenuation or loss of the original sound, isn't as pronounced. Whales use this even more so, by using long wavelengths to talk underwater, much like we bounce radio waves off the ionosphere. We hear sound when the vibrating air molecules hit our ear drum, which then also starts vibrating like the end of the slinky.

The sounds in the OP are from electro-magnetic waves that travel at the speed of light. These EM waves are sinusoidal (curvy like a camels back) waveforms, of which there are many from infra-red to gamma to visible light. These waves can have many different frequencies (the distance between the peaks and troughs). If the wavelength is long, they are towards the radio frequency part of the electro-magnetic spectrum. If the frequencies are very short, they could be X-rays.

The alien sounds are just radio waves. They are all around us but we can't hear them with our normal hearing because they are out of our auditory range. We use aerials that resonate with the frequencies (tuning) allowing you to listen to your favourite radio station.

The alien noise is just a collection of 'random' radio waves that's fed into a spectrum analyser which then interprets it into sound.

In regards to the sounds with fractile video, I wonder if anyone has studied and paired sounds with crop circles and how it would sound.

thanks for your reply!



You too P.O.S. it is things like this that make me love the this site.

I found this interesting, what if we could turn that sound into a picture somehow? The exact opposite of what that program does. That would be cool to see.
