Just think, Brad Plunkett; Gave the pop-rock world the wah-wah pedal and served optical compression on a solid state plate. He gets not a cent in mailbox money for it.
Brad and I both signed away rights to inventions, knowingly, when we joined the various companies as employees or consultants. It wasn't fraudulent on the part of the companies. It may not feel fair but it is legal. I later learned that David Griesinger figured out how he could be a consultant AND get royalties from inventions like Logic 7. This was news to me, probably went up Harman Corporate's a$$ "about a mile and a half" as DeLeonard puts it, and I wish I had heard about it before I signed rights away. But then they never did anything with my really valuable imvention anyway, as I did not champion it. It's now been infringed on to death and would be impossible to extract value from.

But we techies must remember: we are not in this primarily for the money (unlike the jazz musician <jk>). We like to design cool things and play with them. When we find an outfit that "allows" us to do this, we're just so happy, at least until we realize that we're often treated like dirt and cast aside at the first sign of a downturn, while the clueless managers cite their courageous actions firing (oops I mean "laying off") us. Or perhaps our significant other gets a little impatient that we're not "keeping up with the Joneses". The management path probably doesn't appeal, and most of us are lousy at it anyway (you can't let go), but for years few companies realized that; finally some notable exceptions emerged, a promotion track that recognized technical and creative prowess and did not require becoming a manager (AD Fellow for example).

Some of the things they are doing

Yes Kindhornman
GMP is a gray patch over a too long knitted dark canvas.
Even if Americans turn underweight, even if Greeks disappear from the earth (we are working on this), there are huge populations underfed for centuries that have to be fed.
We should expect the same suspects to work out a “solution” to this problem

The problem is more man that vegetable.


Yesterday I was informed that I have lived far too more than I should.
Guilty, I am part of the problem, although my 70kg body doesn’t need much , I can live on beer.

You and the Cretans.
It was the Achaeans :D

Was it that bad?

No it's not, the claim has been made that it filters "unwanted" noise in preference to a desired "noiselike" signal (which music can look like to a demon). This does violate the rules. But of course your test shows that it in fact failed to pass noise when it was the "signal".

It passed less noise than a test sine wave at a specific current and source impedance.

I think we both do not believe it listens to the music and lets that pass but not the noise.

Again my testing is to see if it is different than a resistor!

Of course if it turns out it can really tell the difference between noise and music, I'll have to use it in my interrossiter!

Yes it is nice, no direct reports, budgets, etc. anymore. Most large companies have equivalents at some places like IBM the bar is very high, basicly you have to have written the standard text in your field, etc.

It probably filters 'noiselike' signal that would appear about the same as unwanted noise. Jack does not like to admit to this, but I am pretty sure it can happen in some cases. Still, making the sound palatable, rather than annoying, is worthwhile too!
This is one of the reasons that we never added Bybee devices into the CTC Blowtorch. When you have a very pure though-path, you don't need them. Still, the power line is usually pretty dirty, and I have found that they tame speaker problems.
The sort of 'info' that they MIGHT absorb, is usually not recognized by Bybee's critics in any case. It is just too low in level. Mid fi would not usually detect it.

My limited Bybee experience shows similar results, topnotch equipment has limited positive results and other stuff it works on. I don't know if they have special properties or not beyond being resistors I will admit to being far from the smartest guy posting here though. I won't be putting magnets on my airplane fuel lines though.

My favorite IBM story was when a guy that worked for me and had a beard visited IBM and was taken around the place, at one point winding up at the cafeteria. As he slid his tray along each server would ask Will you be having the roast beef or the chicken, Doctor?, or Will you be wanting the mashed potatoes or the rice, Doctor? etc. At the cashier, That will be 2.93, Doctor. When he and his escort were seated he asked about all the Doctor stuff. "Oh, here at IBM, only people with PhDs are allowed to have beards".
 
Unfortunately, the Bybee device is but one of many useful 'improvements' for the discerning audiophile. And there is much more that could be talked about that might give some useful input on how to make one's audio playback system perform its best.
Of course, I have tried for years to convey some of these ideas, on this and other websites, without much overt success. Still, that is where audio designers, like me, operate on a daily basis, as we make newer and hopefully better products.
For example, I recently got a call from Charles Hansen. We haven't spoken for months but the interval could have been last week. We have NO problem communicating about audio improvements, and it should be the same here. Alas, it is not.

No end to it --

One of my oldest friends (he used to be the singer in our band) worked at the Watson center. Yes, bearded, yes, PhD. He was annoyed that he couldn't get the yearly research awards because his office was a few doors down from Benoit Mandelbrot.

There is no end to it --- at LLNL, PHD phycists with a lot of experience were Sr and when the project needed two phycists, the Sr would mentor a talented "junior' level PHD. There is no end to the fine tuning when it comes to positions. Even a PHD isnt enough to make you top dog in some ivory towers of research.

I would like some advice, I have been looking at waveforms of instruments and music, and waveforms of various types of noise, and both look quite similar, to my untrained eyes. My question is how does the Bybee differentiate between the two.



Back in the seventies or eighties there was a device which was an electronic click and pop remover. Somehow it detected a click or pop on the record because the waveform was different from music. When it detected this click or pop, it gave a short duration dropout, which was not supposed to be detectable.

That is what the review said and I was not into electronics at the time, so I never investigated how it did this. Apparently the device worked fairly well, I still kick myself for not getting one.

I do not know how or if the Bybees work but apparently music can be detected from noise by waveform, at least in some cases.
