Leopold Stokowski: Goodbye.


In 1940, before the world would be plunged into a half decade of devastating conflict, a larger-than-life cartoon creator teamed up with a wild-haired orchestra conductor and unleashed a fantastical film that would forever change the way we experience movies. The morning after the gala event at the Broadway Theater in New York City, The New York Times critic Bosley Crowther said, "The music comes not simply from the screen, but from everywhere; it is as if a hearer were in the midst of the music." Even with all the wondrous characters, vivid animation, and whimsical storytelling of this new film, it was the sound that stole the show.

Chocolate Milk

chocolate milk

"All you need is love. But a little chocolate now and then doesn't hurt."
Charles M. Schulz

Chocolate MilkThere's a phrase we use in the audio industry to explain to someone that doesn't understand that when something's been mixed down, like a song, it can't be unmixed. In other words, once all the elements have been married together, we can't easily pluck out the vocals and replace them. The phrase goes something like, "Here's a glass of milk, and here's chocolate powder. Mix the chocolate into the milk and you have chocolate milk. You can't take the chocolate out and just have milk."

Well, we are all eating a big ol' crow sandwich with chocolate sprinkles on top right about now.

Finch's FAX

"I got a chain letter by fax. It's very simple. You just fax a dollar bill to everybody on the list."

Steven Wright


William G.H. Finch had a crazy idea. He liked efficiency, and he liked news. He imagined a future that would merge those together for the average American. Americans like Joe and Jane. When they woke up in the morning, this crazy idea goes, a box in their parlor had just printed out the latest news onto paper with stories and pictures, ready to be poured over while eating their breakfast. Wait – that kinda sounds like the here and now. What's crazy is that this brainchild was born in 1933.

The Sound of a Lockdown

1950s-radio-dj

"In radio, you have two tools. Sound and silence."

Ira Glass


As the world holes up in their houses during this coronavirus, as we absorb media like never before, as we listen to the news coming out of our television and radio speakers, we see and hear just how serious most of us are taking this. Journalists are broadcasting from their backyards, their sources are interviewed over Skype or Zoom, and the news now looks and sounds less-than-polished. It's like Sunday afternoons on FaceTime with the family three states away. These are the choices we are having to make these days: quality of content over quality of sound and video. But we don't know how good we got it.

The Sound of Progress



"These fellows blow their horns just to see the people jump, I believe."

Chicago Mayor Carter Harrison, 1902

At the turn of last century, the automobile was poised to overtake the horse as the preferred mode of personal transportation. But there were detractors to the coming sea change. Much as we see driverless cars as a potential danger today, "horseless carriage" opponents saw the drivers themselves as dangerous. Many laws were passed to protect pedestrians and horse-drawn carriages that seem silly now, but these edicts were taken very seriously back then. For instance, a person was required to walk in front of a self-powered carriage waving a red flag; a motorist had to fire off a signal firework every mile; or a driver had to ring a bell or gong when approaching people or other vehicles.

In 1900, the race was on to find the best engine plant for these new-fangled contraptions. Most were noisy and smelly, particularly the steam-powered auto. The ubiquitous gasoline combustable engine wasn't quite developed or refined yet. From 1895 through 1905 the electric-powered vehicle (EV) was the best-selling automobile, partly because it was quiet, easy to operate with its shiftless transmission, and it didn't belch out smoke. But the noisy, smelly, and ultimately cheaper gasoline and diesel engines would win the race. EVs were expensive, technologically difficult, and recharging and range was limited because electric power grids were sparse and in their infancy.

That's a shame, because our world would be a much quieter place had EVs won out as the dominant transportation method. Imagine walking down Main Street USA and not hearing revving engines or loud buses and trucks. Imagine a NASCAR race where the pit crew wouldn't have to wear hearing protection. But would we be safer? Our ears would be, but maybe not our bodies.

In a recent study submitted to the British Parliament by the charity Guide Dogs, it was found that EVs and hybrids were 40% more likely to be involved in an accident that harmed a pedestrian. Blind and limited-sight people can be in real danger around EVs, not to mention all the distracted pedestrians staring down at their phones. I understand this problem because I once skirted serious injury from an electric vehicle. Downtown San Francisco has all-electric restored antique trolley coaches that ride on rubber tires and are very quiet. As I casually stepped off the curb, I just used my ears to "look" both ways. I stopped myself in the nick of time and within inches of a passing trolley coach.

The alarms, bells, gongs, and fireworks have been sounded regarding quiet cars. Starting this year in the European Union (and next year in the U.S.), EV and hybrid vehicles must make artificial noise under certain conditions. When traveling under 12 mph (18.6 mph in the U.S.) or backing up, these vehicles must produce a sound similar to a combustion engine, but no louder. The sound must also indicate speeding up or slowing down, comparable to what a combustion engine would do.

How are the manufacturers responding? Jaguar's first all-electric car, the I-Pace, has a very "Tron" like sound when it accelerates. Nissan's Canto "sings" as it drives. Mercedes-AMG is working with the rock band Linkin Park to find a sound for their luxury cars. And not to be outdone, Porsche offers a $500 option in their EV sports car Taycan called "Electric Sport Sound," which "enhances the vehicle’s own sound and makes it sound even more emotional — both outside and inside the vehicle."

The laws mandating that EVs sound like smog-belching, gas-guzzling cars has me wondering what EVs would be compelled to sound like if they had won the auto race a century ago. Would we be hearing a clopping and snorting Clydesdale? A stagecoach driver whistling and whooping? Time will tell if any of these new solutions work, otherwise we might have to go back to waving a red flag. In the meantime, I'll need to decide which sound my future driverless all-electric car will have. Right now it's a toss up between the Jetson's flying car sound and a horse-drawn carriage.

Listening to Light

"Again and again, the cicada's untiring cry pierced the sultry summer air like a needle at work on thick cotton cloth."
Yukio Mishima

Recording location audio outside can be challenging at best. The video team wants an exterior shot because architecture or a landscape in the background can add to the image. But alas, there are often unwanted sounds like cars, HVAC blowers, and other manmade annoyances that we must work around. There's one sound though that is nearly impossible to eliminate, fix, mask, hide, or yell-at-to-be-quiet. It is guaranteed to ruin almost any exterior recording in the summer: the mating song of the cicada.

"It's an interesting place to be. I recommend it."
Astronaut Neil Armstrong commenting about the moon



Every time I hear the timeless phrase Neil Armstrong uttered while stepping on the moon, I can't help but remember the first time I heard it. It was 50 years ago at about 11:00 PM on July 20, 1969. I was eight-years-old and had fallen asleep waiting for them to get out of their strange looking space craft. Our family was vacationing in a cabin on a lake in southern Ohio, and Dad had hauled our portable black-and-white TV from home. We had a lot of trouble getting any TV stations out in the country on that little box. I seem to remember him fiddling with the rabbit ear antennas and positioning all of us at different places in the room like chess pieces so the picture wouldn't flutter.

Audio Letters to Home

"It was easier just to say it out on a tape than trying to write it because it will take a lot of writing paper in order to get it straight."
Private First Class Frank A. Kowalczyk
Long Binh Post, Vietnam, 1969

Back when it was expensive, or impossible, to call someone long distance, friends and family members would send messages on records and tapes to each other through the mail. Not only was it more affordable, it was a more personal way to stay in touch with each other and have some fun doing it. When I digitize some of these audio letters for customers, and feel like I'm transported back in time that a way that a letter can't take me.

Retro Rewind

"Nostalgia is not what it used to be."

Simone Signoret

Record stores all over America will be opening their doors on April 13th for National Record Store Day. But cassettes are sneaking in through the back. These portable petite plastic packs from the past now have their own Cassette Store Day each year in October, and they're winning over some fans that also shop for vinyl. In fact, annual sales of music cassettes were up 23% in 2018, and 70% since 2016. Artists and studios are rethinking this ancient format and not only re-releasing albums popular during cassette's halcyon days, but new music as well. What's with the retro rewind?

Shortwaves, Long Memories

PhilcoS

"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.

Calling All Cars

adam12

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.

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.

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. More on that later.

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. In fact, I often have trouble hearing conversations at loud parties and can't hear high-pitched whines that drive 20-somethings crazy. But I do think I have better hearing than a lot of other middle-aged folks only because I've protected it all these years.

Listening to the Enemy

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


These days, it seems nothing is secret. We can't talk on the phone, cruise the internet, or walk down the street without being snooped on electronically. Enemy anxiety, especially since 9/11, has driven governments to monitor everything being said. Think it's bad now? During World War II it was even worse. Everyone had to be careful about what they were saying and who was listening because "loose lips sink ships." There wasn't the level of electronic communications in the 1940s as today, but the groundwork was being laid for modern tech that we use every day. Even snooping technology.

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


What did Paul Revere's famous midnight ride from Boston to Lexington sound like in April 1775? If you were there, you might recognize the approaching horse as a Narragansett Pacer mare. This once popular breed of horse, now extinct, was known for its ambling gait: a smooth riding four-beat gait that is faster than a walk, but slower than a canter or gallop. You might also notice the calm surroundings interrupted occasionally by crow calls, trees rustling in the wind, or the occasional farm dog barking at the stranger barreling down the rough dirt road. Just someone in a hurry.

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.

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.

The Loudest Record!!!

"Every crowd has a silver lining.”
P.T. Barnum

126.4 I think that's what will be inside a little oval sticker that I'm going to put on my bumper. I see "26.2" bumper stickers that marathon runners proudly display. Colorado mountain climbers have "14er" stickers. A lot of dads are number "1." Then what's so special about 126.4? It used to be a number for Kings, but now it's a number for Cats.

Before I start to sound like a broken record, let me back up and tell this story from the beginning. Team Cornett wanted to raise the profile of UK Health Care and their close association with UK Athletics, so they came up with a plan to get the attention of a sports crowd. There's no better place for a hyped up crowd than Rupp Arena in downtown Lexington. With nearly 24,000 people, its been known to get really loud in there. It would be the perfect place to try and break the world record for the loudest crowd roar at an indoor sports event. And what basketball game would have the biggest and loudest crowd?

Laser Listening

"The key to this plan is the giant laser. It was invented by the noted Cambridge physicist Dr. Parsons. Therefore, we shall call it the Alan Parsons Project."
Dr. Evil
Austin Powers

Here's something that will blow your mind and make you paranoid at the same time. Someone can listen to your conversations in your house or office from hundreds of feet away using light. The "light" is a "laser," and it's bounced off a window pane to detect sound vibrations. It's hard not to imagine Dr. Evil, played by Mike Meyers, air quoting "laser" when we mention that word. The theory was first proposed in the 1940s, but had to wait until lasers were actually invented in the 1960s to gain traction. By the 80s, the Cold War had us and the Soviets spying on each other using "lasers."

A Siren's Song

ASirensSong

“Square in your ship's path are Sirens, crying beauty to bewitch men coasting by;
woe to the innocent who hears that sound!”

by Homer in The Odyssey


I live on a busy street. My house sits roughly between three hospitals - all with helipads and emergency rooms. That's good for me if I have a really bad day, but my poor cat thinks wolves are after her whenever someone else is having a really bad day. I'm talking about the incessant sirens going up and down my street. And they seem to be getting louder – they penetrate my windows and brick walls with even more ferocity than ever before. It turns out that I'm not imagining this, because some emergency vehicles are now employing something called "low frequency system," or LFS. I call it "Loud F*@#$%^& Siren."

In addition to the regular high yelp of a siren, you may have noticed a lower yelping sound that seems to penetrate your car and go straight through your chest. That emergency vehicle has a secondary siren system that emits powerful omnidirectional bass tones from about 200-400 Hz. In this range, sound is "felt" more than heard - up to 200 feet away. These frequencies can penetrate auto glass and metal, wood and brick buildings, and human flesh and bones.

Anatomy of an Audio Book, Part 1

Jun 2016sm

“I love audio books, and when I paint I’m always listening to a book. I find that my imagination really takes flight in the painting process when I’m listening to audio books.”

Thomas Kinkade


There was a panic in 2009 during the recession, and it wasn't about housing. Or at least traditional houses. Publishing houses were facing the pinch as sales were cut in half. When it came to audiobooks, sales were down 20 percent mid-year. One of the reasons was obvious – lack of disposable income. Millions of workers were laid off and even more were holding on to their precious cash reserves. But a few other reasons were staring the publishers in the face. One was the sky-high price of audiobooks. The other was the changing pace of life. Between carting kids around, going to work, and running errands, a book is a commitment of precious time.

"I hate modern car radios. In my car, I don't even have a push-button radio. It's just got a dial and two knobs. Just AM."

Chris Isaak

Maybe you haven't noticed, but AM radio has pretty much sucked the last twenty years or so. Maybe you didn't notice because you weren't listening. A lot of people aren't, and the FCC is out to change that. The FCC? You bet – this isn't your father's FCC. We're so used to hearing "FCC" and "restrictions" in the same breath, that broadcasters were pleasantly surprised last October when the FCC announced an "AM Revitalization" initiative.

"They number girl spies different. She's what you call a 36-23-36."

Max Baer, Jr. as "Jethro Bodine"

Double-Naught Spies

This month, the new James Bond spy movie Spectre will be released. It's the 24th film in the long-running franchise based on Ian Fleming's novels. "Hot Dog!" as Jethro Bodine would say. James Bond and all his gadgets were hatched from Fleming's experiences while serving in the British Navy Intelligence Division during World War Two.

Gathering intelligence during any war requires innovative and clandestine communication techniques, especially deep within the enemy lines. In the Revolutionary War, invisible ink and garments on a clothesline were tools to send secret messages. The Civil War saw women disguising themselves as nurses, slaves, and even soldiers to gather and smuggle information. During World War One, the human body itself became a vehicle for secret messages via invisible tattoos.

"Podcasting - I swear to you - on its worst day, the podcasts are better than our best films. Because they're more imaginative, and there's no artifice, and it's far more real."

Kevin Smith

Podcasting Revisited

Modern podcasting has now been around a little more than 10 years now. The roots go back much further, into the 1980's in fact. The idea of subscribing to an internet-delivered audio service dates to the early 1990's. But it wasn't until portable devices, such as the iPod, came onto the scene that it really took off. History shows that portability drives popularity – the battery-operated radio, the portable record player, the audio cassette, and the funky 8-track. I remember the iPod being described as a digital "Walkman," even though poor Sony already had moved beyond the cassette into portable digital players.

"In radio, they say, nothing happens until the announcer says it happens."

Ernie Harwell
Legendary Detroit Tigers Announcer


There was a time when Americans who wanted to sound important and upper class spoke with a half-American, half-British accent. They call it mid-Atlantic, presumably because the accent lands somewhere in the middle of the ocean between our countries. It was dominant in movies, on radio, in theaters, and on early television. Today, it sounds pompous. Some early practitioners were Franklin Roosevelt, James Cagney, Orson Wells, and Katherine Hepburn. Some more contemporary holdouts were William F. Buckley, George Plimpton, and Jacqueline Kennedy Onassis.

Audio Clichés


You're watching a movie and somebody rides by on a bicycle. What do you hear? Ring-ring! Yep, it's a tried and true "audio cliché." I'm guilty of using it. Or how about when the scene shifts to London, we see the House of Parliament and hear Big Ben striking it's bell. Or a jet touches down on the runway and we hear the screech-screech of the tires.

We use clichés in everyday life, it's how we communicate. Sometimes it's just so easy to use a tired phrase like "next thing I knew." I cringe when someone says "at the end of the day," or "it's a win-win situation." I wish those people would just "think outside of the box" so they would have a "paradigm shift" and "take it to the next level."

HELLO...Hello...hello

Hello
"Any effects created before 1975 were done with either tape or echo chambers or some kind of acoustic treatment. No magic black boxes!"

Alan Parsons

Echo, reverb, delay, and ambience. There's a difference between them (see "Tech Notes" below) and they're often confused with each other or used incorrectly. But each one has an important place in recording with technology often dictating their use. Reverb/echo/delay can make or break a recording. Thanks to the American Legion Hall in New York City, Decca Records found the perfect effect for Bill Haley's "Rock Around the Clock." Columbia Records built their own "echo chamber" for such hits as Dave Brubeck's "Take Five" and Miles Davis' "Kind of Blue." And U2's Edge has created a patented sound for his guitar with electronic delay.

Early recordings were often done in large halls and spaces. The natural ambience and reverb of the space helped the realism. But the tinny-sounding jukeboxes of the 1930's and 40's had trouble translating the core sound above the reverb. The jukebox operators complained, so the record companies began recording everything with a very dry sound, until...

Hi-Fi came along. After WWII, recording to magnetic tape became the standard (read more about its introduction into American music). It revealed much more detail than disc recording did. In 1951, Mercury Records decided to take advantage of this fact by introducing the series "Living Presence." Spearheaded by husband and wife team Bob and Wilma Fine, these carefully executed classical recordings went on to critical and commercial success until 1967. The first recordings were in mono using the storied Telefunken U-47. Seeking more detail from the orchestra while maintaining the rich natural reverb, Bob turned to the handmade omnidirectional Schoeps M201. It would become the permanent staple for these recordings. When Bob started recording in stereo in 1954, he used three M201's (left-center-right onto 3-track magnetic tape, later mixed down to stereo).

Producers and engineers didn't or couldn't always go to large spaces just to have reverb, so they started to create it artificially. Artificial reverb was already showing up in a few hit records before Bob Fine stuck his U-47 up on a stand. Bill Putnam of Universal Recording built the first "echo chamber," a separate room that included an amplified speaker and microphone. It was actually his bathroom, but the Harmonicats took "Peg o' My Heart" all the way to the top of Billboard's chart with that atmospheric reverb.

With Putnam's cleverness and Fine's success, all of a sudden reverb was HOT! Capitol Records built an echo chamber in 1953, and all of the other big record companies soon followed. Many Frank Sinatra, Beatles, and Doors recordings used the echo chamber. But an echo chamber took up valuable real estate. One clever solution was to divide a room into two, with an opening on the end of the dividing wall - basically U-shaped. The signal from the control room would come from a speaker on one end. The sound traveled down the room, around the corner, and into the microphone at the other. They were usually located in basements for isolation. There are tales of engineers hearing water dripping in the effect, only to find flooded basements. Another engineer went down to troubleshoot why the reverb sounded muffled and found a homeless person living in the chamber. Some studios are still using some of these original echo chambers.

What about electronic reverb? Spring reverbs were first used in the late 1930's, mostly in guitar amplifiers. The sound could be "boingy" and unrealistic, but studios on a budget used them anyway. The "plate reverb" made its debut in the late 1950's. The "plate" was a 40mm thick sheet of steel measuring 1 x 2 meters. It was suspended in a tubular frame with springs and mounted in a soundproof chamber or box. A driver with the studio send signal was placed in the middle, and a contact microphone (or two for a quasi-stereo effect) was placed on the edge. Rigidity, thickness, damping, and choice of driver and mic shaped the sound. The EMT 140 plate reverb was a 600-pound behemoth with a price tag to match, and was popular in larger studios and radio stations. It usually had a big sound, and AM radio stations in the 1960's and 70's capitalized on this by using it on most programming.

Tape delay was another artificial reverb used mostly in rock music in the 60's and 70's. A track was fed into another recorder, which was fed back into itself post-recording, creating a delay feedback loop. Some musicians that used it for its signature sound were Elvis Presley, Led Zeppelin, and Pink Floyd. Reverb was so wildly popular, that cars in the mid-60's began offering it as an option on the radio.

By the early 70's, analog circuits started showing up that achieved similar results as the tape delay. The 80's microchips brought digital reverb and delay boxes. It was hard to resist, and the "Big 80's" was born. The 90's brought digital reverb into the PC. And the last decade has seen mind-boggling advances in artificial reverb, including the "acoustic stamp," which models decay and character using actual recordings in real environments.

If you can believe it, people are still building new echo chambers, plate reverbs, and spring reverbs. Sometimes that organic sound is just too hard to emulate digitally. Even the early digital reverbs from Yamaha, Lexicon, and Eventide still command big bucks on the used market. Many of these "old" technologies and echo chambers are digitally sampled and used as software plugins. I have a few digital reverb boxes from the 90's that still sound superb. Maybe I used one on your project.

I hope you enjoyed this look back at the origins of reverb and echo in recording. There are so many interesting stories that I don't have the time or space to relate. So without further delay, I will now say GOODBYE...Goodbye...goodbye.

A Sound Education

“Education is the kindling of a flame, not the filling of a vessel.”
Socrates

What young person really knows what they want to be when they grow up? Very few of my childhood friends are still on the path they laid out early in life. Most of us have zig-zagged through careers, including me. Unlike today, if you wanted to be an audio engineer in the 70's like I did, there were very limited educational opportunities. Most recording engineers started as musicians or disc jockeys and fell into the job. As a teenager in the late 70's, I was into music more than anything. I hung out in radio and TV stations and got my first exposure to a "real" recording studio in a friend's basement. I was a child of tape. In fact, as a child I ran around my house with a cassette recorder taping anything that I found interesting. I would often shove a microphone into the face of a shy family member, who would naturally be at a loss for words. But when a teen nears graduation, the pressure builds into making that big life decision - "what will I grow up and be?"

3D Audio on the Right Track


It's said that when an early motion picture was first shown to the public, women fainted and men ducked from an approaching train. The director made a bold new decision that would alter the course of filmmaking for the next century. Instead of just placing the camera in front of all the action like an audience watching a stage, the director moved the camera to a new position - within the action - to create perspective. That’s been happening in filmmaking ever since. But the same has been happening in sound as well. And now with emerging technologies, virtual 3D sound is now here.

The Color of Sound


How would you describe a sound to someone without using descriptors that are unique to sound, like: loud, bassy, shrill, whining, atonal, or noisy?

Not a problem, because we most often describe a sonic experience with words related to our other senses: sharp, warm, angular, raspy, piercing, even, warbling, soft, smooth, or flat.

What about blue? I think of that as more of a style of music or mood instead of a type of sound. Why don't we use more colors to describe what we hear? Probably because a "yellow" sound could be cowardly. A "green" sound may be eco-friendly. A "purple" sound is probably regal. A "brown" sound - well, we'll leave that one alone.

What if we could see sound? Aside from graphical representations of sound like waveforms and meters, we can't just look at an orchestra and see sounds flying out of the trombones. I wish we could watch the beautiful tones flow from Itzhak Perlman's Stradivarius.

But we can - sort of. As reported by NPR, we can see certain sounds using a technique invented in the mid-19th century. Click on the link above to read about and watch a short video describing this process to get a clearer picture. To simplify, scientists watch the disturbance of heat waves by sound. Ever look down a highway on a hot summer day and see the heat creating wavy images? Scientists have used this phenomenon to "see" sneezes and aircraft wing turbulence. But Michael Hargather at New Mexico Tech uses it to study explosives.

So what's next? I would love be able to put on some goggles and see sounds and where they're coming from. Loud sounds would be bright. Bass would be blue, treble would be white, and green, red, and yellow would fill in the gaps. Imagine seeing green waves and ripples emanating from the violas, bubbles of blue from the tuba, and distinct columns of yellow and white from the violins. It would be like Peter Max was the conductor. With technology advancing at such a rapid rate, this may not be so far-fetched in our lifetimes. Color me crazy.

Did You Know?

  • "White noise" in sound engineering describes randomly generating all the sounds in the frequency spectrum. SInce the sounds aren't generated at the same time, they are measured over a period of time. Each sound is at a consistent level.
  • 600px-White_noise_spectrum.svg
  • White noise sounds similar to a radio that is tuned to no station.
  • White noise is often used in large offices to mask sounds from workers, computers, and other office machinery. People also use white noise generators to aid in sleeping.
  • "Pink noise" is similar to white noise, but decreases in intensity each ascending octave.

  • 600px-Pink_noise_spectrum.svg


  • Pink noise is primarily used to measure the output of an audio device.
  • Sound engineers play pink noise over monitor systems to check frequency response and level of speakers. If measurements show that a speaker produces some frequencies differently than the pink noise (more bass for example), then it is considered to have a "colored" response. Pro audio speaker manufacturers strive for a "flat" response from their products. This way an engineer isn't fooled into compensating for the difference while mixing.
  • Live sound engineers use pink noise to reduce feedback and get maximum performance from speakers.
  • Other types of noise used in analysis are violet, brown(ian), gray, blue. Other informal names for sound used in measurement are red, green, black, noisy black, and noisy white.


Tech Notes

Reducing feedback in a live sound situation is very tricky, especially if good sound performance is desired. The "squeal" you hear when a microphone is turned on is from a buildup of a certain frequency. It's usually the point at which the microphone and speaker are the most efficient. If one points a microphone at the same speaker that is amplifying it, then serious feedback occurs. Most speakers are placed in front of or beside performers so there is no direct bleed back into the microphone. If speakers are placed behind the performers (think The Who), then eliminating feedback is a bigger chore.

How do you eliminate feedback? Let's use the simplest set-up as an example: one microphone and one speaker. A graphic equalizer (GEQ), a device that increases or reduces frequency by octaves, is inserted after the microphone channel and just before the amplifier. The engineer slowly raises the amplifier level until the first inkling of feedback. Using the GEQ, the engineer locates the offending octave, ex: 630 Hz, by actually increasing that frequency creating more feedback. That octave is then reduced until feedback goes away.

Next, then amplifier is turned up a little more until the next inkling of feedback occurs, usually at another frequency, which is then reduced. These steps are repeated over and over until the amplifier is at a suitable level without feedback. Of course computer technology has simplified this process greatly with devices that rapidly reduce feedback "on-the-fly." And with software, engineers for permanent PA systems in large venues can even predict where feedback will occur before installation. They can then program in filtering or make changes to the architecture, equipment, or speaker placement.

Hidden Messages

"Fly straight, you beep flag."

Hidden Messages


When astronauts first walked on the moon, everyone was glued to the television. I was eight-years-old and can remember it like yesterday.

Beep. Beep.

We copy you down, Eagle.

Beep. Beep.

Engine arm is off. (Pause) Houston, Tranquility Base here. The Eagle has landed.

Beep. Beep.

What the beep? All those old NASA transmissions seem to have that beeping in the recording. What the beep is it? It's actually two, and they're called Quindar tones.

They were named after the manufacturer, but I think it sounds very '60's Sci-Fi:

"I am from the planet Quindar in the Crouton system. We think your planet is just groovy, baby!"

In a nutshell, the tones signaled remote transmitters to turn on or off. Installing two separate lines of communications, one voice and one data, between Cap Com (Capsule Communications on earth) and the transmitters around the globe would have been extremely costly. So they went with a single channel, and that's why we hear them in the recordings.

This wasn't a new idea. All of us who had to endure a film strip in school remember the tones that told the teacher to advance the film strip. Radio networks used it to signal its affiliates, like the "N - B - C" chimes.

Later, radio networks adopted a different method to cue automatic playback systems at their affiliates with "sub-audible" tones. In reality, they were just low tones like 25. 35, 50 or 75 Hz that were filtered out of the on-air stream and redirected to playback equipment.

An announcer's voice can also be a cue for radio stations. In sports broadcasting for instance, how an announcer goes to a commercial break can cue the broadcast engineer at the local radio station whether or not to play local commercials. If a block of commercials will be all network spots, the announcer might say:

"We'll be back after this on SRN."

If the upcoming break should include local commercials, the announcer might say:

"We'll be back after this. You're listening to the Sports Radio Network."

But the ultimate in hidden sounds has to be subliminal messages in advertising, public address systems, and music. Remember "Paul is dead" from The White Album? How about rumors of hidden messages in department store music, factory brown noise, or even advertising? It's easy enough to do, but is it effective? Studies have found that visual stimuli are more effective than audible stimuli. But it doesn't stop people from trying. I think I'll try. Say the following aloud:

Isn't it a nice day. use You should really go to the country. dynamix Take a picnic basket along. for Enjoy the breeze. all Marvel at all the green. your Smell the blooming flowers. audio Enjoy yourself!

"That's one small step for man, one giant leap for mankind"


Neil Armstrong meant to say "That's one small step for a man," but flubbed his line in the excitement. The one word, or lack thereof, changes the whole meaning. NASA said that static obscured the one little word, but ground recordings are clear and audible. Armstrong hesitated after he said "man," probably realizing his mistake. Having been awake for 24-hours and being the first person on the moon, I would have probably messed up as well...and fell off the ladder landing face up and helpless like a beetle.

Tech Notes


When NASA Cap Com would initiate the conversation with a spacecraft, they would press and hold a button that would produce two tones. This simulated the push-to-talk (PTT) action on a walkie-talkie. The first tone was the "intro" or a "ready" tone for the automatic systems that controlled the transmitters. The next tone, slightly different, told the transmitters to un-mute the audio.

CapCom would then initiate conversation. When everything needed to be said, they would release the button. Once again, a ready tone would sound followed by a slightly different tone. This told the transmitters to mute the audio.

The spacecraft usually didn't hear the tones because a filter was applied that tuned most of the tones out. Unlike a walkie-talkie that mutes incoming audio while transmitting, Cap Com could always hear the spacecraft if they transmitted while Cap Com was also transmitting.
