I'm certain that your questions are precisely phrased, but...
I've no idea at all what your thingy is and what it does. No context at all. So no answers.

[CaptDon]

Dozens of statements and no clear understanding of the final goal!! Tens to Hundreds of thousands of audio streams at once? Horseshit, I would call that noise as nothing would be discernable. How do you propose to combine these audio streams?? Maybe Allen and Heath make a 100,000 channel mixer board? This post is the written version of the Earth, Wind and Fire song called 'Ball of Confusion'. The only 'high voltage' audio devices I know of are the vacuum tube amplifiers with 811A zero bias or perhaps the 833 gallon jugs with ears both of which run 1400 to 2000 volts on the plates. Or perhaps you mean the electrostatic speakers with a KV or so of audio voltage, or perhaps this is an April Fools rant 5.5 months early?

Perhaps the most unfriendly and aggresive welcome to a new user I've seen yet.
Is that the normal social tone in Iceland?

@kristjan: don't run away yet. Most people are friendly here.

[CaptDon]

Well, perhaps you can enlighten us to the O.P.'s goal? I don't see anything in the kilovolt range on the device in the picture. That statement "Can you guess what I am building" short answer "Not a clue". Combining 10K to over a 100K of audio streams at once.....Any clues on how that is done? Or even a clue why? Wouldn't that be nothing more than some sort of colored noise? In which case I would just pass noise through a filter. Hooking the outputs of hundreds of laptops "in series or parallel" sounds more like a troll. Give me a clue as to what is the final goal of the O.P. because in a miriad of text I can't parse it out. Sound more like one of the April Fools articles in QST ham radio magazine. I am not unfriendly, I have been thanked often and helped a lot of folks with useful information but again, after a diatribe of text I can't make heads or tails of the goal of the O.P. and I believe there is truth in my original post. Perhaps you can enlighten me on a way to combine 100,000 audio streams at once? Wouldn't that be a football field of 32 channel mixers somehow summed together? "Will this effect the original resonance tuning"? Of what pray tell? Icelanders are not unfriendly but have short time for the incomprehensible (except it be for trolls, the real kind that live on the lava fields and have a mailbox all their own on a Reykjavik city street)

[CaptDon]

I see you have a 28.7% Thank-You ratio vs. my 25% ratio. Puts us on nearly equal footing overall with you being 10% more 'thankable'. I may however outrank you in snarky comments around 3.579545:1, call me colorful!!

[BillyO]

1500/2000V audio device?   What does this audio device do?

Are you serious or just guessing here?  Or maybe you are trying to use up some extra "0"s.

Just out  of bewildered inquisitively can we get a make/model of this device?  I would love to know something about an audio device that required a 2000V supply.

Physically fitting audio on a 3.5mm cable??!?  Audio is  from 20Hz to 20KHz.  What do you mean "fit on a 3.5mm cable"?

Multiple superimposed waveforms?  What are you intending to do?  If you superimpose multiple audio waveforms they will produce what is called a cacophony.   They will not be severable.  The only way to do this is to encode the audio digitally then transmit it over some appropriate digital media like Gb Ethernet.  then you could "fit" thousands of audio streams and be able to treat them separately.

Without being overly rude via pre-apology, I'm sorry, but I have no idea what you are trying to do and quite frankly, I don't think you do either.

[jonpaul]

My guess is a "plasma speaker" driver.

Or the OP is just another troll or an audiophool

[Haenk]

Why would you run 2kV only to step it down. That's dangerous for a beginner and unless there is a good reason like electrostatic or plasma speakers, no one would even consider using a HV system.
Then what is the plan with hundreds if thousands of audio streams? That's as close to white noise as it gets.
I really can't see the point behind this idea.

[coppercone2]

he said its electrodes, so its some kind of plasma device

to answer all your questions, they use a fiber line, or turn it into RF with many channels that require filters to extract.

so if you want help you need a block diagram of the system

it kind of sounds like a art experiment that asked the question what does global telecommunications sound like?


the question basically is 'what is the spec on a AT&T project office and how could i hook it up to a plasma speaker"

https://en.wikipedia.org/wiki/33_Thomas_Street





and many of your questions will be answered if you read about how submarine communications cables work. One connecting a offshore city to the mainland might be a 'understandable' size explanation.


but before that, try understanding something like a small town telephone switch.. then work your way up. or a microwave data link, or a satellite data link. they all carry audio, and they existed in 1960.

ARE YOU BOB PAGE?

if you wanna learn then learning how the technology was implemented and what the implementations looks like by studying telecom infrastructure is a essential learning aid for the math theory behind all this

First the unfriendliest and now the most irrelevant comment I've read.
I don't even know where you get those figures from, and I don't give a hoot.

But if it tickles your ego, go ahead. There might be other "interesting" statistics somewhere.

There's a significant difference between unfriendly, insulting and uncivil, and "colorful".

[CaptDon]

To the O.P., this idea of your is nothing new!!! Didn't the Nazi's try some of these hyper-learning experiments in the late 30's / early 40's. Learning without visual / audible / tactile stimulus is impossible due to the way the brain processes and then stores information for recall and relational interaction such as visual red may mean hot. Thinking you could target the brain with 10,000+ streams of information at once and have the brain be able to process that information and store it in recall-able manner exceeds all the gallactical stupidity combined. I am learning C++ from a book and having fun doing my own little experiments to see the outcomes. Learning by success and learning from failures. Why don't you take a single channel of some audio book about a subject you want to learn and play it through a 1 kilowatt audio amplifier driving the primary of a microwave oven transformer (It actually should work and not even harm a good quality audio amplifier of that power level) and take the secondary voltage which will surely peak at several thousand volts and apply it to your head through some sort of top secret coupling device and we will see who learns useful knowledge after perhaps 1 year? My money is on book learning or lab experiments with friends / co-workers and sharing little hints and Easter eggs with each other!! As I said, this hyper-learning has been tried with dismal failure being its most worthwhile outcome. May as well read up about Nazi experiments of 'remote sensing'. They had just about as much luck with that.

Benta....Please, for your own sake, put me on your ignore list!!!! You are to easy!!!!

The main point is intended to be one of speed-learning, effortlessly.  <snip> Hence, simple question: Can i fit 999999999999 audio files on a single cable?

If it actually works you will almost certainly become the world's foremost authority on Sturgeon's Law.

Kristian: BRAVO for the effort!

The patent letter:

WOW! I knew Gilles Flannagan, a scion in speech science, he wrote the book on speech engineering.

The PTO Restriction letter is for a speech scrambler patent application, from BTL. It was Later issued 1972.

See SIGSALY for the 1942 multiplexed top secret speech encryption system that could  be relevant to your idea.

Hello again, I just edited my note with adding the Flannigan patent link and image.

Been researching and writing on SIGSALY since 1990s.

Enjoy,

Hello again:  AFIK, no SW implementation  of SIGSALY.

Needs some post grad student DSP experts

The main point is intended to be one of speed-learning, effortlessly. The original device (Neurophone) supposedly transmits the audio
(directly?) into long-term memory centers, bypassing the hearing channels/nerves.

Science fiction, or cold-war thriller plot.  No relation to the real world I'm afraid, ask any neuroscientist.  Useful search term "memory consolidation"
