Sonic Coloring To The Rescue

Sonic Coloring

Even audio enthusiasts avoid confronting room acoustics.
The audio term conjures visions of complicated physics.
It creates images of an expensive and chaotic room remodel.

But your room can kidnap musical goose-bump thrills and serenity.
Sound you dearly paid for.

Here's the good news.
You can reclaim much of it without mind-bending physics or that costly chaotic remodel.

But first, let's dump that intimidating word — acoustics.
Let's call this sonic coloring.
Ah, can you feel the anxiety and dread float away?

The Usual Suspect. The Weakest Link.

The Weakest Link

An audio/video system is only as good as its weakest link.
If UltraHDTV problems arise, the "links" between audio/video components are the usual suspects.
It's particularly true for long-distance cable runs.
The heralded HDMI video solution is a fiber optic active cable.
Yet, video problems may still arise.
Therefore, consider additional suspects.

Don’t Forget Yet.

Piezo Tech

The first line in a Twice story states, "Forget what you know about coil-and-magnet speakers."
The story highlights the limitation of multiple-part (magnet, voice coil, speaker cone) conventional speakers.
The parts present multiple points of possible failure and undesirable resonance. That’s true.

The second line states, "New solid-state devices deliver better, clearer listening experiences."
That’s a bit of optimistic advertising hype.

The new "devices" adapt century-old piezoelectric tech that's primarily limited to high-frequency tweeters.
The device leverages two piezoelectric crystals to improve speaker membrane excursion,
which extends low-frequency bandwidth; interesting cool tech when applied to earphones.

But I'm not yet ready to forget the coil-and-magnet audio headphones from companies such as Grado Labs, Sennheiser, and Shure.

Forgotten Baseball Legend

1800s Iowa Hill Baseball

The gold mining town Iowa Hill, a few miles across the deep and wide American River Canyon as a blue-jay flies from my frond door, is the birthplace of a long and forgotten baseball legend, William "Seattle Bill" James.

William James began his baseball life as the Iowa Hill baseball team water boy.
In the late 1800s, mining towns throughout the Sierra Foothills fielded baseball teams.
Look at the old photo above of the Iowa Hill team and the water boy sitting by the tree holding a watering can in the background.
(The links below offer a better view.)

That boy became a World Series champion with National League Boston Braves in 1914.
In game two, James pitched a 2-hit, eight-strikeout, 1-0 shutout of the Philadelphia A's.

Two day later, the game tied in the 10th, James entered to pitch the 11th and 12th innings.
He held the A's hit-less until his Braves scored in the bottom of the 12th for the final win and the series.
He was the Madison Bumgarner of his day.  James led the National Lague with a .788 winning percentage.
He finished in the tip five with 26 wins, a 1.90 ERA, pitched 332.1 innings, with a 156 strikeouts.

Where will it stop?

Window to the world

HDTV resolution equals more than 2 million pixels.
4K UHDTV resolution equals more than 7.5 million pixel,
and 8K UHDTV is more than 56 million pixels.

It's hard to see even HDTV pixels at a reasonable viewing distance.
So I ask why 8K?

The answer, even though you cannot see the pixels, the brain still responds.
Real-world resolution is nearly infinite.
In the real-world, your brain responds to "pixel" rays of photons you can't see.

Each improvement in television resolution moves toward convincing the brain
that the picture on your TV screen is a real-world window.
That is why this Graphene-info story is interesting.

Researchers have created 4-micormeter red, green, and blue LED TV pixels.
4-micrometers equals 0.00015748031196063 of an inch, or about the thickness of a small strand of hair.
MicroLED TV screens may someday create a picture that appears as more of a window than a TV screen.

David Crosby

David Crosby

Yet another music legend has passed, David Crosby.
My memory of Crosby, Still, Nash, & Young at the Forum in 1970 still gives me goosebumps.
A 1971 Dorothy Chandler Pavilion performance of Crosby and his vocal soulmate Graham Nash confirmed they were the harmonizing glue of CSNY.
I remember a laid-back Crosby solo performance at a San Francisco club in the 80s -- his voice and celebrated music.

An early 70s memory, listening to my favorite FM radio DJ  B. Mitchel Reed, demonstrated how Crosby supported other artists.
Reed invited Crosby and Crosby's guest into the radio booth, Joni Mitchell.
Crosby had just finished the production of her first album.
They played the entire album as they discussed the music.

Producing and contributing to others' work was a common Crosby theme.
Listen to the Buffalo Springfield Steven Still's guitar and vocal fest, Bluebird.
The recording includes Crosby.
Listen to Jackson Browne's "Doctor My Eyes." That's Crosby in the backing harmonies.
He worked with 'The Jefferson Airplane' as the Airplane evolved into ‘The Jefferson Starship’.
This trend continued for decades.
This LINK offers a note from Graham Nash.

Dead Zone Tech
Graphene Transistor


Graphene-info.com offers a geek-speak story about the electromagnetic spectrum.
The spectrum extends from radio waves to x-ray, gamma rays and includes a dead-terahertz zone.


The dead zone includes visible ultraviolet and infrared regions.
Conventional electronic devices cannot efficiently operate in this zone.

However, Japanese researchers have discovered a means of harnessing this troubling region.

This tech breakthrough may produce graphene-assisted transistors for new spectroscopy, imaging, and 6G and 7G tecnologies.

Paul McGowan / PS Audio
Paul McGowan

I generally stay away from citing audiophile stories and reviews to avoid the glazed looks of friends.
But this review of Paul McGowan's FR30 struck a nostalgic chord.

1980 CES Las Vegas, Arnie Nudell unveiled his Infinity IRS speaker system. 

Taller than me, two columns of large woofers, plus two separate cabinet columns of his planar magnetic midrange/tweeters,

a $45,000 price tag to match, and incredible sound, blew us away.
Infinity IRS   
2022, PS Audio released their FR30 speaker system.
PS Audio's Paul McGowan partnered with Arnie Nudell in 1990 to create Genesis audio, a descendant of the IRS.
The PS Audio FR30 continues the tradition of the IRS.  And the FR30 is ONLY $30,000.

Listen, Norm Varney Listens
Norm Varney

I recently read a post by Norm Varney of A/V RoomService.  Norm stated, "It is all about what you have been exposed to – what you've experienced – that is your reference." I agree.  All audio dealers should take a day trip to locate and listen to the most outrageous high-end audio systems.  Use the references to judge more modest audio systems. Then create audio systems that offer a sizable percentage of these references. That's how you can deliver more "goose bump" per minute per dollar for your customers than your competition. Here’s a LINK to his article
What's more exciting than electrical grounding?

Ground Symbol

Well, just about anything.
However, a compromised electrical ground can jeopardize video and audio performance; think video "spark-lees" on your UltraHD TV screen and high fidelity harmonic detail lost in a "noisy haze".  A compromised ground can also expose your electronics to power surges and brownouts.  CEPro offers guidance for high-end audio/video installations that can apply almost any audio/video installation.

$12.6 Million Mickey Mantel Rookie Card

Although a Mickey Mantel baseball card never saw the spokes of our bicycles,
it's not worth $12.6 million, unless it comes with the original bubble gum.

Schrodinger Helmholtz Wrong?

Color Chart

Video-philes are well aware of the CI.E. color chart.  It's based on Schrodinger and Helmholtz mathematical modeling. 
The chart is the reference standard of color measurement used for more than 100 years.

Researchers have discovered that the chart is wrong.  "It overestimates the perception of large color differences. 
This is because humans perceive a big difference in color to be less than the sum you would get if you added up all the small differences that lie between two widely separated shades."

So what does this mean to you sitting in your comfy chair?  And how does this affect ISF-certified video calibrators? 
The answer is not much yet.  But this will ultimately lead to advancements in TV.

MIT Paper-thin Speaker

MIT Speaker


MIT has introduced a paper-thin speaker that is entirely different from a planar speaker such as Magnepan or electrostatic such as the Quad. They did not use stators or magnets.  Instead, MIT employed the principle of piezoelectric.  The speaker relies on a specially-treated piezoelectric film/membrane of tiny domes.  It does not vibrate forward and backward as a whole. Alternating-voltage squeezes/releases the tiny domes.  For more information, select this Link to Audioholics.com.
