www.livingstonintegralstudies.com contains pages about Restorative Up-Sampling (RUP) and Quantization Error and Artifact Reduction (QEAR). These ideas were initially visited years ago, but had some deep flaws. With maturing vision, and a greater commitment to mathematical rigor (as much as I can muster), they may be ready now for an audience. I still have my doubts about them, but figured it might be time to share. They draw inspiration, in part, from Michael Talbot's book, "The Holographic Universe."

Thanks for your time...

The algorithm might work, but not in the way as described.
A signal surrounded by infinite silence is essentially limitlessly “zero-padded” in both the positive and negative directions, and it turns out these zeros contain information
:clown: yes, a lot of nothings izzzz.... Nothing!! :lol: :nutter:

Let's try that teleportation machine then.

I'm sorry, but you really did not manage any as far as I can see.
Preferred pronouns would be "it/it" because according to this country, I'm a piece of human trash.

As I review my results again, I am dissatisfied. The pages have been taken down. Sorry for wasting you guys' time, but I thought I was on to something...

Oh bummer. Your article about zero-point energy was a fascinating read though. Thanks for sharing.

We're all responsible for our own wasting of our time. Time is far more precious than energy. Energy never really gets wasted, it just goes into a form or place we cannot use for our own profit anymore. Time on the other hand can be spent only once.

I noticed an egregious error in my RUP White Paper work, the correction of which actually simplified matters. The web-pages are back up, edited substantially. I have made less attempt to claim a rigor and elegance I can't seem to achieve, and am mainly limiting myself to prose, algorithm code, and results: www.livingstonintegralstudies.com

...Cheers.

Hi KVR Readers:

I buckled down and wrote some MATLAB code (more popular platform), debugged and ran it on a newly purchased copy of MATLAB, and in the process, found a small error in my DADiSP code which magnified to affect the output files on the website. I believe the error has been rectified, both in the MATLAB code for (RUP) and the DADiSP code as well. The output files on the website have been updated, and the code appears there. MATLAB code for (QEAR) is pending...

Thanks to a gentleman at DSPRelated for a dialog which seems to have corrected a flaw in my reasoning.

Hi KVR-Audio Posse:

Results of of integrating some of deanpk's (from DSP-Related) suggestions into the Restorative Up-Sampling algorithm, along with a substantially modified and, thankfully, less lengthy White Paper discussion are available at www.livingstonintegralstudies.com

I view the improvements that he has made possible through generous dialog as being quite marked. Only the DADiSP platform code is currently available, but I am pondering a MATLAB translation. I have yet to check my Noise Reduction (QEAR) outputs, as I get perhaps a little superstitious about looking success or failure in the mirror without the buffer of another human consciousness of good-will "holding space" for me, as it were, but I am waiting on feedback locally.

Although I haven't looked myself at anything other than the Restorative Up-Sampling (RUP) outputs, which I thought sounded good, the results of the (QEAR) Noise Reduction are available to you at the website.

...Cheers.

There is a very simple way to test a new theory. Just make a product, and watch the market trend. Over all these years, I've learned that the public, over a very long period of time, can spot something that works, and simply help it grow. If there's an item being used there's always a motivation underneath - sometimes it's not even enough to capture the imagination, because there's always someone in the crowd who has the means to dismantle something that doesn't do what it promises to do.
The problem of making something new at all costs then is unavoidable: to stay on the market, if an object is not new it must have better execution than others, or develop an idea in a way that no one has ever done. Otherwise it will get lost in the noise.

hello i've been away from this forum for over a year and have finally logged back in and can report that the unchecked madness that is this forum, where i'm never sure if people are joking or really actually being serious, hasn't changed a bit and i hope it never does

I have written, run, and debugged some MATLAB code for the current versions of the RUP and QEAR algorithms, and this appears on the website posted here: www.livingstonintegralstudies.com ...Furthermore, I had embedded a scalar multiplier in the RUP code that seemed to be boosting the higher frequencies of the output at the expense of the lower frequencies. This misguided scaling factor was not called for by theory, and was situated in the middle of a 'for' loop... not the place to adjust final output levels.

Check out the results of this change if so moved...

Again, thanks for your patience with my, perhaps, arcane way of using your forum, and...

...Cheers.

hello. i am definitely a fan of whatever it is going on here. my earlier comment was like writing on a bathroom wall to no one in particular or kvr at large, thought i should disambiguate that
