Reiki viewed via an Oscilloscope
Please bear in mind that this wasn't recorded under controlled conditions in a lab - it was more of a trial run out of curiosity to see if it was possible to visualise the sounds in this way. For the technically-minded among you, the Oscilloscope is a digital instrument which allows observation of constantly varying signal voltages. Signals such as sound and vibration can be converted to voltages and displayed, and analysed for properties such as amplitude, frequency, rise time, time interval, distortion etc.
These screen shots of individual images taken from the video give us some interesting insights:
Thanks to Shahead Mostafafar for these images.
I'm not a technical geek so my understanding of the process by which this was achieved and the reliability is pretty sketchy. Shahead has tried to explain it simply for me. He tells me that the first thing to note is that single source frequencies don't work on an Oscilloscope. If you play a single vibration and send it to an Oscilloscope it will show nothing more than a single line. Secondly, he tells me that if you play two different frequencies on a single source and send it to an Oscilloscope you will still get nothing more than a single line. He explains that the first step is to make two different sources and send them to a master output line, for example kHz and kHz. If you add two mono channels and send them to the Oscilloscope you will still get nothing, but if you locate one of the mono channels on the left and another on the right and send them to the Oscilloscope a shape will form. He initially added two mono channels and tuned the first at 432Hz and the second at 528Hz. Then he made the first channel completely left source and the second channel completely right source, at which point the imagery becomes visible.
It should be noted that the Oscilloscope is very sensitive to clearness and other noise. It only needs a little bit of hiss or some high frequencies in the 14000-20000 range and the image gets lost. In this case, our audio file was pretty noisy with unwanted static, background noise etc. Therefore Shahead edited out all unwanted noise and amplified the main vibration. once that was done and he had a clear image on the screen he left the sounds to express themselves. I then added the original mp3 file over the top of the resulting video, so that it made it a bit clearer for anyone listening what the audio originally sounded like.
