It was to do with bit identical rips sounding different depending on whether the ripping gear was powered by a SMPS or a linear, or something similar, I would have to dig into the past to confirm.
Do we fully understand the effect of electromagnetic waves on the human body?

Without some of them we all die. Plants need some also.
Some wavelengths affect the zeta potential. (Patents on using that effect.) Others warm us up.
But others cause voices to appear as if by magic inside small boxes.
If you click on his name, one of the options presented to you is "find all posts by john curl". If you select that option you will discover that someone made a post here on diyAudio, yesterday, under that userid.
Yup. I fully go along with/expect that for a bunch of reasons, mirrors my experience/knowledge/endeavors.
I would be interested to take a look if you can find it.
Certainly generally it is not understood, even slightly understood.
Add to that a lot of alarmist stuff without proper/wrong explanations and associated usually expensive/very expensive product 'remedies', most of which are actually deleterious but not all.
This subject is part of my focus, and I am turning up some very interesting proper solutions and reasons for variation/excess in sensitivity in particular individuals, although we are all being affected/effected by natural and man made EMR to varying extent and modalities.
Funny enough a GF just now sent me this quote from 'Little House On The Prairie' of all things...
I have realised the second line since a very long time ago, and has been my creed ever since.
By this I have no trouble reading between the lines of a wide range of information that comes my way and by using my faculties and my senses I easily see/sense/know and correlate what many do not.
There is a lot more to EMR than the label EMR, and understanding the depths of this provides the solution, totally obvious when the hypnotising veil of standard education is lifted.
So, EMR is not of itself a problem actually, the problems are to do with modulations and non linearities.
The key is in understanding and controlling modulations, which can be employed as remedial and maintaintitive agents.
Sadly the opposite is the usual through innocent ignorance, but can be by design, certainly this is possible.

Dan, what is 'reading between the lines of a wide range of information'? Something is information or it isn't; what is in between are half truths. Your subsequent claim, that you correlate much of this 'harvest' in ways that others do not, is troublesome.
Seeing patterns in half-truths is a major temptation to the lazy brain. No good has ever come of it.
Bit identical... its impossible.... If you come up with a realistic theory then you will totally re-right all we know about data storage and retrieval, it would be greater than a Noble prize, it would be up there with the theory of relativity... but unfortunately bits are bits and the information stored in a data file is identical if the bit pattern is identical...
On first inspection, sure.
Yes, and not the first time that I have heard that.
I don't have a theory, but do have observations, and verified by others.
File metadata like 'date created' is the only data change that I can think of.
On first inspection, sure.

I said 'many do not', that does not mean all.
Reading between the lines and correlating means bringing together observations from many fields, and using knowledge in fields to understand observations in other fields.
My observations are rigorous, but no solid theories yet, sorry about that.

You should see a doctor. Delusion of this magnitude is a symptom of a mental disorder.
On a different topic.
A local service station has newly opened in the area 600m away, and the aircon plant equipment is setting up a disturbingly loud hum and very low frequency erratic drone throughout the otherwise essentially silent neighbourhood.
Does anybody have ideas on how to record sound down to a few hertz, perhaps even lower.

The Analog Discovery USB box records down to DC directly to .wav files, you can set any sampling rate you want to save space and only capture the low frequency information. There must be other boxes like this.

I sympathise.
Such a case drove me mad for three months ( a large A/C compressors installation on the roof of a building 50 m away from a flat I was living in a few years back) .

Either through the air or through the ground, the subsonic frequencies enter the building and a whole lot of resonances adds sonic frequencies to the mix.

Thanks Scott, I more so mean suitable microphone to capture this ELF stuff.
I have just turned up some diy stuff that looks interesting, including using a woofer mounted in a 44 gallon drum as an enclosure. I have a couple of 15" subs cabinets that would likely work.
Other methods include gluing a neo magnet to a rubber baloon stretched across a downtube pipe, and a sensitive coil used as the pickup/transducer....an old school ignition coil would likely work well enough.

The two audio files on the page are pretty close to what I'm talking about, ie 50Hz or thereabouts hums plus ELF products, must be intermods ?.
This service station/aircon plant is right in the middle between a sandhill and a large storm water catchment pit.
I'm betting that sandhill delayed reflected sound and the catchment pit are setting up a resonance condition that is hugely amplifying the small but erratic speed variations in the fan motors...the ELF stuff sounds 1/f in nature and the distances and dimensions I think correlate with the observations.
The 50Hz hum itself is loud enough to be audible, and the ELF is too much to bear....this ties in with the ESS Dac technology video posted around here the past view days in respect that it is the spectral changes that the ears/brain picks up, not so much the actual ELF frequencies.
What is becoming a sincere pita might turn out to be an interesting research project, the next step is in finding a solution.
