Shortwaves, Long Memories

Pasted Graphic

"TV gives everyone an image, but radio gives birth to a million images in a million brains."
Peggy Nooman


The recent presidential elections in Nigeria and Senegal stirred fond memories of my childhood. Specifically the "sounds" of Africa I remember growing up with. I haven't had the good fortune to go to Africa, but I've listened to it from afar. In the 1960s and 70s, radio was perhaps at its peak. AM radio stations played the hits, FM radio played the albums, and CB radios were in kitchens and cars. A lot of homes also had a shortwave radio. Today it's the internet that ties us all together. Back then, CBs connected us with our friends, AM and FM connected us with the country, and shortwave connected us with the world.

The Loudest Sound

Pasted Graphic

My favorite saying is, 'If it's too loud, turn it up.'

Tori Amos

You often hear the phrase "The shot heard 'round the world," referring to the first shot fired of the American Revolution in Lexington, Massachusetts. Or for us baseball fans, Bobby Thompson's dramatic game-winning home run when the New York Giants beat the Brooklyn Dodgers for a trip to the 1951 World Series. Both of these pale in comparison to the 1883 explosion of the Krakatoa volcano. Dubbed as the loudest sound in history, it was also the farthest traveled.

Calling All Cars

Pasted Graphic

10:40 p.m. “I got about 2,000 college students coming from Walnut Street to 30th to Center City.”
10:46 p.m. “It’s endless, chief. Endless.”
11:11 p.m. “They’re on top of trash trucks. There is to be no one on top of trash trucks, guys.”
11:14 p.m. “We have multiple people on Broad Street swinging on light poles.”
11:20 p.m. “Climbing the trash trucks at 13th and Market.”
11:25 p.m. “I need to get the fire extinguisher out of my trunk. I got a fire on Broad Street just south of South. Someone lit a Christmas tree on fire.”

Philadelphia Police radio transcripts after the Eagles won the 2018 Super Bowl

Do you remember the old movies from the 1930s when a radio in a police car would blare out "Calling all cars! Calling all cars!" The diligent policemen would zoom away in their car with the siren screaming. The dispatcher had no idea if the radio cars heard the frantic call because two-way radios were uncommon and expensive. So from the late 1920s until after World War II, most police departments relied on their cruisers having radio receivers only. Today, police use digital radio systems that carry data, video, and other information.

The Birth of Home Recording

7818086c-cd5f-48a8-9e4c-90b161a45663
"I bought a Dutch barge and turned it into a recording studio. My plan was to go to Paris and record rolling down the Seine."
Pete Townshend, The Who


I'm conflicted on the topic of recording music at home. The business part of me frets about studios losing out on billable hours. The musician part of me relishes creating art in a non-pressure environment. But the history of artists recording radio-ready songs in their humble abodes goes back further than you might imagine. Let's explore how affordable home music recording for the masses came to be, but also look back at the origins of this revolution in recording.

11th Hour Message

1-field op

"Hostilities will cease along the whole front from 11 November at 11 o'clock."
Marshal Foch, the French commander of the Allied forces via radio atop the Eiffel Tower.

This week marks 100 years since the end of the war to end all wars, known today as World War One. In 1918, on the 11th hour, on the 11th day of the 11th month, 1,500 days of fighting came to an end. The armistice was agreed upon just six hours earlier in a railway car halfway between Paris and the Western Front. What's remarkable is the speed at which most troops were informed of the impending armistice. This war, like in so many other ways, forever changed the world of communication.

Video on Vinyl and Other Turntable Transgressions

Pasted Graphic

"Hello from the children of Planet Earth"
From the gold records aboard the twin Voyager spacecraft

Vinyl is the format that won't die. It'll probably still be around after humans are extinct and our sun has gone supernova. Perhaps in eons, Voyager spacecraft with the golden records aboard will meet distant stars and future vinyl lovers. But in this eon, people will not stop pushing vinyl to its limits. Mad scientists and crazy artists like putting something other than music on it - or in it.

As Seen on TV

Pasted Graphic

"Treat the recording studio as a laboratory for conceptual thinking — rather than as a mere tool."
Brian Eno

When I was young in the...cough...60s and 70s, the only real glimpses I got inside a recording studio was through television and movies. There was a smattering of documentaries and behind-the-scenes footage of studios and radio stations. I was always straining to see the control board and tape machines, or marveling at the cavernous studio on the other side of the glass. It was absolutely riveting to peek inside them and see how a record was made. The 8-foot long mixing console was often shot through a fisheye lens. Long-haired musicians were sunk down into a couch smoking cigarettes (?) and listening to their masterpiece. And there were close-up shots of that big fat 2-inch tape rolling past the heads of the recorder.

"He who knows that enough is enough will always have enough."
Lao Tzu
Father of Taoism


When is enough, enough? When do you stop finessing, polishing, correcting, perfecting, or otherwise fixing something important you're working on? When you're done – either because of deadline, budget, or exhaustion – are you satisfied? Don't overkill your project.

Golden Ears

Pasted Graphic

“My dear girl, there are some things that just aren't done, such as drinking Dom Perignon '53 above the temperature of 38 degrees Fahrenheit. That's just as bad as listening to the Beatles without earmuffs!”
James Bond
"Goldfinger" (United Artists)



The other day, someone said to me, "You must have golden ears." He was referring to my profession as an audio engineer. He assumed that I physically had much better hearing than the average person. I don't. So I explained to my acquaintance that I have trained myself to listen for things that the average person might not hear right away. Want to try yourself?

Listening to the Enemy

May 18 News

“The only real way to disarm your enemy is to listen to them.”
Amaryllis Fox
Writer, peace activist, former CIA Clandestine Service officer

Eavesdropping on the enemy in times of war can be essential to victory. During World War Two, a tucked away family farm in New England would save thousands of lives while being a key to Allied victories over Germany and Japan.

How Hollywood Hears History

"The people will waken and listen to hear
The hurrying hoof-beats of that steed,
And the midnight message of Paul Revere."
Henry Wadsworth Longfellow


How authentic should sound designers be with history? If we were telling the story of Paul Revere's famous ride with sound, should I be accurate, or should I make it sound "Hollywood"?

Ghost Whispers

ghost-2857971

"I have been at work for some time building an apparatus to see if it is possible for personalities which have left this earth to communicate with us."

Thomas Edison, 1920


What if you nonchalantly recorded something around your house, let's say a music practice session. Then when you played it back, you clearly hear someone whispering. You didn't hear it when you recorded it, so what was it? Many unfamiliar sounds throughout history can be attributed to nature, machinery, and even hoaxes. As our post-industrial society grows, so does the list of unexplained sounds, like trumpet sounds from the sky, humming cities, and ocean whistles. The proliferation of audio and video technology has generated its own tally of the strange. Specifically, weird voices that have been inadvertently and unknowingly captured. These recordings and transmissions sound eerie but have a very unsexy-sounding name: "Electronic Voice Phenomenon," or EVP.

We're Fifteen!

Neil at 12 playing DJ

"I will never be an old man. To me, old age is always 15 years older than I am."

Francis Bacon

Dynamix turns fifteen years old this month. Well technically sixteen, because I incorporated a year earlier and did small jobs out of my basement until I could step out on my own. When I did, I couldn't have timed it better. As I wrote about in our ten-year anniversary newsletter, the Great Ice Storm of 2003 delayed our opening for a week. In fact, I was stuck in Dayton, Ohio for several of those days.

A Myth-terious Thing

2015-March Myth-terious

"Any sufficiently advanced technology is indistinguishable from magic."

Arthur C. Clarke



To the average person, audio can be a mysterious "myth-terious" thing. Many people don't want to admit that they are intimidated by the technical side of it, and that makes sense. The closest most people get to manipulating audio is adjusting the volume on their stereo. I bust 10 common myths about recording audio.

The Shadow Knows

2018Jan-ShadowEffect

Shadow: No, Mary. I suspected a trap, so after I opened the door, I walked across the room and stood behind them.
Apple Mary: But your voice.... it came from near the door.
Shadow: Ventriloquism. A simple trick of projecting the voice.

The Shadow
"The Blind Beggar Dies"
Radio broadcast: April 17, 1938


We're fooled by Mother Nature all the time. She uses light to conjure up a mirage on a hot desert day and Aurora Borealis on a cold Alaskan night. She also has a bag of tricks for sound, like flinging noises a hundred miles away. But one of her best is when she makes sound disappear. This slight-of-hand by Mother Nature may have even changed the outcome of several battles in the American Civil War. What are these shenanigans of sound? Magic? Illusions? Sorcery? As the old radio serial hero said, "Only The Shadow knows." They're called acoustic shadows.

Wagner, Vader, and the Viking

Brunhilde

"The opera ain’t over until the fat lady sings."
Ralph Carpenter, Texas Tech Sports Information Director



Richard Wagner, the 19th century German composer, would have loved Star Wars. He may not have understood what a light saber or X-Wing fighter was, but he would get it - even with his eyes shut. That's because the Star Wars films are rich with composer John Williams' scores that employ a musical tool that Wagner himself was a master of: the leitmotif.
