Sam here and this goes much deeper than i ever thought.

Hypersonic frequencies are defined as those above 20 kHz.   A CD, and a lot of digital audio media, are limited to 22.05 kHz as that is the Nyquist frequency that is 1/2 the sampling rate of 44.1 kHz.  Interestingly, the 22.05 kHz CD limit is just slightly higher than the 20 kHz limit of most audio tape recorders used by recording studios.

Granted, there are systems like RADAR that could record at 96 kHz and 192 kHz, but when reduced to a CD or other digital media, it still comes out at a maximum of 22.05 kHz due to other bandwidth limitations.

Using the theory of Occam's Razor as a guide, it makes more sense that recording (music) companies would work within the bandwidth limits established by the recording equipment and industry standards rather than conspire with a totally unrelated industry (pharmaceutical industry) for a, yet to be defined, provable reason.

Since digital has a fixed upper frequency limit, I really need a thorough explanation as to HOW hypersonic and especially EMF is encoded onto a digital recording.   EMF is measured in Volts per meter (V / m) being radiated.  HOW, exactly, can an audio speaker, headphones, or earbuds generate an electromagnetic field that can be measured in Volts / meter?   

Pretty interesting discussion.  Lots of people say that cables and power cords make no difference.  Can't be measured, so how can it matter???  

Since Covid, my stereo sounds much better.  Less mess on the power grid because business in Silicon Valley are shut down (employees working from home).   Interesting that a possible solution is dismissed out of hand. 

I've lost my marbles - I ordered a Shungite stone to check it out.  Not much of an investment, and who knows.  Anyone use footers on their equipment??  How could those possibly matter.....

Sam here and my test confirm that the size of the shungite makes no difference. This is where i got my shungite straight from russia
https://karelianheritage.com/shungite-products/shungite-for-emf-and-5g-protection shungite phone sticker cost $4.00 peel the sticker on the back and place the shungite directly onto the inside of the circuit breaker box found usually in a closet connected to the wall with a metal door.Shungite is a conducter of electricity. Using my safe living emf/rf meter i was able to prove that 1 small flat piece of regular shungite (30 to 60% carbon) removes 100% of the dirty emf from the wiring preventing it from ever entering your living space. When the dirty emf reaches 2000khz it jumps the wiring and becomes rf radiation and this is preventable with a $5.00 rock. Shungite is 100% natural and can not be patented. Removing dirty emf from the wiring in your living space will make your digital audio sound like 1st press vinyl cut from analog reel to reel as long as the player is plugged into the wall and if your on your phone or dac player simply transfer the music to your portable device from your pc with the shungite on the circuit breaker and the music on your portable device will sound like analog cut vinyl. Shungite never goes bad and never loses it’s power however once a month rinsh the shungite in warm water and place in the sun for 2 hours to clear the rock and energize. For some reason if you place the shungite directly onto your smart phone or portable player it will remove the emf/rf however the results don’t transfer to the audio your listening to like streaming audio for example. Be carefull as shungite will break if you drop it on a hard surface. Do yourself a faver and put a piece of shungite in the bathtub for a 20 minute soak and say goodbye to aches and back pain and make sure you get your throat under the water as i gained 2 octaves to my singing voice and throat feels amazing.

I'll take your word for it. Did you write that yourself or was it cut and pasted off one of those Goolag Translate pages?

I cannot believe you guys are still thinking he may be serious.
sam, hats off to you.
This is trolling at its finest.
You have taken it to a level beyond the reach of the mundane.
Kudos to your creativity and imagination.
