Before There Was Vinyl

Like many audiophiles I have appreciated the recent surge in the popularity of vinyl recordings. There is not only a marked difference in sound quality but there is also something satisfyingly tactile about placing the record on the platter and positioning the tonearm, triggering for yourself the moment the music begins. Putting an audio CD in the slot and watching the machine suck it in or tapping an icon on your phone just doesn’t have the same vibe.

That said, there is an even older format than vinyl that we are not very likely to see come back in the same way – beetle resin. That is to say – shellac.

That’s right – beetle resin. Shellac was used for a variety of things in it’s heyday from furniture and violin finishes, to fingernail polish, to electrical insulators, to..  well, records. If you have ever watched an old movie and seen someone break a record to stop it from being played again, it’s very likely it was a shellac disc because they were quite fragile and shattered quite nicely. Some of you will point out that vinyl breaks as well, and while that is true it just isn’t as easy to do as with shellac and in movie making you go with what works consistently.

The records ran at 78 rpm which is why you most often hear them referred to as 78s rather than “shellacs” and their fragility plus the fact they are made from beetle secretions is why you’re not likely so see this little piece of nostalgia on the shelves at Best Buy® any time soon. That doesn’t mean there is something wonderful happening with them however.

I recently became aware of The Great 78 Project, and effort by the Internet Archive, George Blood L.P., and The ARChive of Contemporary Music to preserve for posterity as many 78s as they can, physically and digitally.

The digitization work is being done by George Blood L.P., and will be made available to the public for download – FOR FREE! Great news for audiophiles and soundscape designers everywhere.

For the techies among my readers, I would like to point out that this is not easy because unlike their vinyl descendants, shellac records were not all created equal. Other than the fact they all rotated at 78 rpm (more or less) there were differences in manufacture from one publisher to the next, including diameter, groove size, spiral spacing, and shellac formula (some were softer than others so too heavy a tonearm might damage the groove). For the most part shellac records were designed to be played on the machines manufactured by the publisher of the music. They didn’t want you playing other company’s records on their machines and if you wanted you play their music you needed their machine. Kinda like Apple®.

As you can imagine this makes getting an accurate digitized copy challenging because it’s hard to tell exactly what the recording was supposed to sound like. George Blood met this challenge by, among other things, creating a turntable with four tonearms, each with a different size stylus. The full story on the digitization process can be found here.

The Great 78 Project is out to preserve as many 78 recordings as they can, not only sourcing them from artists and collections at various museums but they want your 78s as well. You can donate your old 78s to the project or they will advice you on the best way to digitize your collection and then you can upload the digital files to the project for inclusion.

“I think the Net generation is beginning to see knowledge in a way that is closer to the truth about knowledge — a truth we’ve long known but couldn’t instantiate. My generation, and the many generations before mine, have thought about knowledge as being the collected set of trusted content, typically expressed in libraries full of books. Our tradition has taken the trans-generational project of building this Library of Knowledge book by book as our God-given task as humans. Yet, for the coming generation, knowing looks less like capturing truths in books than engaging in never-settled networks of discussion and argument. That social activity — collaborative and contentious, often at the same time — is a more accurate reflection of our condition as imperfect social creatures trying to understand a world that is too big and too complex for even the biggest-headed expert.

“This new topology of knowledge reflects the topology of the Net. The Net (and especially the Web) is constructed quite literally out of links, each of which expresses some human interest. If I link to a site, it’s because I think it matters in some way, and I want it to matter that way to you. The result is a World Wide Web with billions of pages and probably trillions of links that is a direct reflection of what matters to us humans, for better or worse. The knowledge networks that live in this new ecosystem share in that property; they are built out of, and reflect, human interest. Like our collective interests, the Web and the knowledge that resides there is at odds and linked in conversation. That’s why the Internet, for all its weirdness, feels so familiar and comfortable to so many of us. And that’s the sense in which I think networked knowledge is more “natural.” ”

A great many things have happened on December 6th over the centuries, but for audio buffs the world over one event stands out above the rest. It was on this date in 1877 that the first audio recording was made by Thomas Edison. Previously, April 12th was considered to be the anniversary based on a date Edison wrote on a sketch of his device made in 1917; but subsequent research has revealed that Edison had misremembered the date and now many historians accept December 6th as the date of record. (pun intended)

That first recording was made with the assistance of Charles Batchelor and John Kruesi. Working under the Edison’s direction they created the first phonograph consisting of a cylinder with a sheet of tinfoil wrapped around it.  Sound was received through a funnel, which was connected to a diaphragm. Yelling into the funnel caused sound waves to vibrate the diaphragm, which in turn vibrated a small stylus (needle) that was attached to it. The stylus pressed the pattern of the sound waves onto the tinfoil as the cylinder was turned by a hand crank.

The indented tinfoil sheet then was moved to another, nearly identical, device that had a stylus attached to the diaphragm with a delicate spring. As the hand crank was turned this time the stylus was passed over the indents on the tinfoil. The indentations caused the stylus and thus the diaphragm to vibrate in the same manner as when the original words were spoken. The vibrations of the diaphragm were amplified by another funnel and, if one listened closely, the recording was  heard.

Kreusi, who actually built the device from Edison’s sketches, is credited with the first review of an audio recording. His response? “Gott in Himmel!” (God in Heaven!)

The tricky part was turning the crank at the exact same speed as when recorded so the sounds could be recognized. Those early tinfoil recordings were quite fragile and could be played only a couple of times before they would become damaged and be lost forever. In later, more commercial models, wax and other materials would replace the tinfoil.

And what was that original recording you ask? It was Thomas Edison himself reciting the childhood classic “Mary Had a Little Lamb“. As already mentioned, those tinfoil recordings were fragile and the 1877 original is lost forever, but the following link will let you listen to a re-enactment made by Edison at the Golden Jubilee Celebration of the Phonograph made in 1927.

Today, 134 years later, quality recording technology is readily available to almost anyone. You probably have one in your pocket or purse right now. Few inventions have contributed to the shaping of culture and society world-wide as the ability to record and distribute the human voice.

In celebration of this world changing event I leave you with my favorite recording of “Mary Had a Little Lamb” by Stevie Ray Vaughn.

Give It a Second…

Came across this video today at The Long Now Foundation.  It is a great commentary of increasing impatience with technology.

I’ll be the first to admit I have an obsession with technology.  There is little that gives me more satisfaction than finding the right technology to simplify a task.  But as Louis CK points out, I think my fascination is born out of the fact that I remember when we had the dial phones. I remember my aunt who was on a party line and I had to wait until the neighbour was finished before I could make my call. I remember going to Malton Airport in Toronto for an afternoon to do nothing other than watch the planes come and go, amazed that something that big and heavy could actually fly.

Yeah. I know. I’m showing my age. But that’s okay. I’ve waited a long time to be this old and experienced and I’m going to relish every minute of it. So have a little patience, it wasn’t all that long ago the cell phone in your hand was the stuff of science fiction.
Till next time… give it a second!

Among the many shades of gray that make up my reality we find my role as technical director for Kortright Presbyterian Church in Guelph. This role requires that I try to keep abreast of what’s what in the world of technology, such as Audio and Video systems, Computer developments, and of course, the Internet.

In regard to the third item on that list one question that pops up from time to time is, “Just how big is the Internet anyway?” I’m sure if you haven’t actually had this discussion with anyone, you have probably wondered about it at least once in your life. So here then, presented for your perusal, are the latest figures from Pingdom, an Internet uptime monitoring firm in Sweden that is very good at keeping track of this sort of thing. The blog article can be found here, but the following are some of the highlights.

Email
1.3 billion – The number of email users worldwide.
210 billion – The number of emails sent per day in 2008.
70% – The percentage of emails that are spam.

Websites
186,727,854 – The number of websites on the Internet in December 2008.
31.5 million – The number of websites added during 2008.

Domain names
77.5 million – .COM domain names at the end of 2008.
11.8 million – .NET domain names at the end of 2008.
7.2 million – .ORG domain names at the end of 2008.
174 million – The number of domain names across all top-level domains.

Internet users
1,463,632,361 – The number of Internet users worldwide.
248,241,969 – Internet users in North America.

Blogs
133 million – The number of blogs on the Internet (as tracked by Technorati).
900,000 – The number of new blog posts in a day.

Images
19.2 billion – Photos hosted by Facebook, Flickr, and Photobucket. (my note: This actually represents a small percentage of the images available when you consider these three only account for 3 out of 174 million web domains.)

Videos
12.7 billion – The number of online videos watched by American Internet users in a month.
34% – The increase in viewing of online video in USA compared to 2007.

Malicious software
1 million – The number of computer viruses in April 2008.
468% – The increase in malicious code compared to 2007.

With an estimated world population of 6,706,993,152 (according to the CIA) the above figure means roughly 22% of Humanity is connected to the World Wide Web which is 16% larger than a year ago, 1 in 5 of us don’t write letters much anymore, North America has only 17% of the Internet population, and yours truly constitutes a mere 0.000002% of the Blogosphere. How’s that for a little perspective?

But while these numbers remind me just how small a part of the whole I am, they also remind me of just how quickly our world is shrinking. (I’m going to do a little ‘old guy’ shtick here so be warned and bear with me.)

You see when I was a kid, long distance phone calls from England were still a really big thing. The whole family would gather round and wait almost breathlessly for our turn to say ‘Hi’ to Grandma and Grandpa. I’d get a letter from my penpal in Australia about every other month. When I did get a letter from him the information was already at least two weeks old. The encyclopedia set my parents bought me for high school cost over $1000 dollars and was somewhat out of date by the time I finished.

Now, well you know how it is; through Skype I call a number of people all over the world every day and gripe if the sound quality isn’t up to my 128bit 44.1kHz standard, Facebook’s status line tells me what my friends in Malawi were doing as little as 30 seconds ago, and about $50/year gives me access to the entire reference edition of Encyclopedia Britannica which is constantly updated month to month.

So, what’s my point? Well, the scriptures tell us that God separated the people at the tower of Babel because as one unified force they were getting ideas too big for them to handle. They began to think there was nothing they couldn’t do and were losing perspective as to where they fit into the grand scheme of things. They began to think of themselves as gods. So God confused their language making it harder for them to communicate and therefore harder for them to collaborate on the insanely big stuff, like skyscrapers.

Today technology is reversing what happened at Babel. Every year we grow closer to being a true world-wide community. Every year scientists, engineers and guys tinkering around in the garage (yes that still happens) build on each other’s work to create ever increasingly spectacular feats of technology, some of which has us once again infringing on God’s domain.

In his book ‘Unceasing Worship’ Harold Best points out that we are all worshiping all the time. It is the nature of our being to worship. The key point is who do we worship at this moment, the Creator or the creature. As I watch technology continue to progress I can fully appreciate the temptation to self-worship. We have accomplished a great deal in the lifetime of the human race, and it does indeed seem that there are no limits as to what we might accomplish in the future. But I would ask us all, my self included, to remember that for all our creativity we are only building on what God has done before us.

You see, it’s not about skyscrapers – it’s about how we think of ourselves, and our place in God’s creation. We have learned to do marvelous things with resources such as iron, oil and silicone; but we still have to go looking for them because we have not learned to make them. Only God can do that. We can clone a sheep named Dolly and engineer a tougher tomato by introducing animal genes to its DNA; but we still can’t create life out of lifelessness. Only God can do that. We can communicate ideas, and pack a million calculations into ever more infinitesimal periods of time; but we can’t stop time from rolling on or reverse it’s direction. Only God can do that.

And dispite all the advances in technology we have made, in one thing we have not advanced hardly at all. What has not changed is our propensity to use our creativity to find ever more inventive ways of hurting, oppressing, and killing each other. Despite our best efforts to the contrary greed, pride and ego remain the most prevalent motivations for our advancing technologies. We find we cannot escape the nature of our fallen existence as we continue to exert our superiority over the planet and each other. We cannot wash away the stain of what humanity has done with its creations over the millennia. We do not have within us the capacity to make right the burden of sin that we have created by how we treat each other and our planet.

Only God can do that.

Well, It would seem that folks surfing the Internet in the People’s Republic of China are not allowed to read the musings of yours truly.


But then that’s hardly surprising when you think about it. I mean, it’s not like they would want the Christians in China being encouraged, or exchange ideas about what the Bible is really saying, or learn something of church history. No we can’t have that now can we? If you want to know if your favorite URL is blocked in China check out The Great Firewall of China. Just enter the URL in the space provided and see if their test location can access your site from inside China.

Sarcasm aside, it actually serves to remind us that we are extremely privileged in this country. For all of our complaining about inept government, inconvenient bureaucracies, lengthy commutes and the lineup at Tim Hortons, the fact remains that we are the most fortunate people in the world.

We live in a country where we are free to vote for the worst candidate, make the wrong career choice, and over indulge our every desire. We can be complete and total idiots and the only consequence will be those of our own making. There’s no one telling us where to live, what to do for a living, or what to think. We can worship who we want; Jesus or Buddha or Mohammed or no one at all. And it’s all because of the men and women who made the ultimate sacrifice to secure these freedoms for us.

So I add my voice to the hundreds of others and ask you, when you see the poppy displays at Tim Hortons, or the veterans in the mall with the poppies and pins, please give generously, shake a hand, and say, “Thank You!”
