Get the boom out of the room

by Paul Strikwerda in Articles, Studio 21 Comments

When I decided to become a full-time voice-over artist, I made myself a promise.

I would never lose an audition because of poor audio quality.

They might not like my voice. They might not like my read, but I would not let them ditch me because I wasn’t able to deliver broadcast-ready audio. In order to get there, I needed two things:

1. A dedicated, isolated and treated recording space

2. Quality equipment 

I purposely put them in that order. You can place the best equipment in a poorly isolated and barely treated room, and you’re still going to sound like an amateur at the kitchen table. I’d rather take an affordable microphone and preamp into a (semi)-professional booth, because the end result will be much better.

So, if you’re wondering where to spend your money, buy a Studiobricks cabin, or build your own space like I did. Then we’ll talk about getting that coveted Neumann U87 Ai, okay?

I still remember the day my 7′ by 7′ recording space was finally ready. The floating studio walls consisted of multiple layers. Auralex® Mineral Fiber and Green Glue were sandwiched between several sheets of 5/8″ drywall. All the seams were caulked with SilenSeal.

Outside noise was kept at bay, but inside, the space sounded like this:



Unknowingly, I had created an echo chamber! It was an ugly beast, waiting to be tamed. Especially in small spaces with parallel walls like mine, flutter echoes can be a big problem.

The best way to kill those echoes, is to put foam or other absorbing materials on the side walls. As a rule of thumb, the smaller the space, the more acoustical treatment you’ll need. Thankfully, I had a whole bunch of Auralex® Studiofoam Wedgies left over from my previous space.

I covered parts of the wall with SoundTrax™ from NextAcoustics™ and I added four CornerBlox™ bass traps, also from NextAcoustics™. The SoundTrax™ took care of the mid- and high frequency reflections. The bass traps absorbed the lower frequencies.

If you’ve ever seen pictures of my studio, you probably know that it’s also my office. My Mac Mini, Grace Design preamp and A/D converter sit right next to me in a small cabinet. Behind me are two bookcases, and I’ve lined the backs of those cases with Sonex Mini acoustical Panels.


In spite of those panels, I felt I was still getting too much reflection from the back. I tried to remedy that by taking a room divider and placing it behind my chair. I then took an old duvet cover, a few blankets and a sleeping bag, and hung them over the divider for absorption, creating a rear reflection screen. It wasn’t pretty, but it did the trick. The boom was out of the room!

Unfortunately, my improvised contraption was heavy and unstable. It also had a life of its own. I can’t tell you how many times it decided to fall down on me, usually in the middle of a recording. Two months ago, I had had it with this thing and I started looking for a replacement.

My search lead me to GIK Acoustics, a company that is selling in the U.S. as well as in Europe. They make a wide range of high-quality acoustic panels, bass traps and diffusors.

I especially like the fact that GIK uses ECOSE® Technology in their products, a formaldehyde-free binder, based on renewable materials instead of petroleum-based chemicals. It’s used in wood based panels and glass, rock and mineral wool.

GIK makes a versatile screen panel (32″W x 72″H x 3″ thick) that seemed ideal for my booth. Audio engineers would call it a Gobo. That’s slang for a portable acoustic isolation panel. Some people believe the word “Gobo” comes from “go between.”

Being the gearhead I am, I enjoy watching these types of videos. But when I watch something that’s put together by a manufacturer, the skeptic in me always wonders: does the product actually live up to the hype? I’ll let you be the judge, because I ordered a Gobo!

First, let’s listen to something I recorded in my booth without the GIK screen panel. You might want to use your headphones for this. 


As you can hear, compared to the first sample, room treatment makes a huge difference. However, for me the sound wasn’t quite dry enough. You can hear a bit of reverb at the end of each sentence.  

Once the GIK panel came in, I made two modifications. I added wheels so I could easily roll the panel into position, and I added handles. That way, I wouldn’t have to touch the coffee-colored fabric while moving the panel.

Here’s me reading the same lines from my booklet “Building a Vocal Booth on a Budget,” which is available in my store. This time, the Gobo is in place. By the way, both samples were recorded in WAV-format and converted to MP3.


Having used the screen panel for a few weeks now, I can confirm that it absolutely delivers as promised. It’s well-made, easy to position and it comes in many colors.


Even though this screen panel is portable, it’s great for a studio but too big for road trips. So, what do you do when you’re fighting flutter echoes in a hotel room? Well, there’s a solution that fits into your computer. It’s a De-Verb plug-in made by SPL, which stands for Sound Performance Lab. It’s a German company.

Originally developed to shorten the sustain period for drums and guitars, I’ve found that it also works well in the vocal booth, as long as you use it wisely. Once you’ve recorded your audio, you simply select the De-Verb plug-in from the effects list. This what you’ll see:

The left button controls the level of reverb reduction and the right one the output gain. Both can be operated with the mouse wheel. When diminishing the reverb, you also diminish the output a little bit, and that’s why it’s good to turn up the gain slightly.

Now, don’t expect this plug-in to “fix” the first bit of audio you listened to (that’s the sample I recorded before I added any treatment to my booth). It’s by no means a substitute for acoustic panels or foam. However, if you’re recording in a less than ideal setting or you like your audio “extra dry,” this will definitely add the finishing touch.

Here’s the sample I recorded without the screen panel in my studio. This time, I added a bit of De-Verb. Once again, I recommend you listen with your headphones on. You might want to start by listening to the first sample, followed by this one. That will give you a nice contrast. 


Perhaps you find the difference quite subtle. To me, it’s just one of those small changes that, when you add it all up, can set you apart and take your product to the next level.

But how do you know that these changes really matter? Couldn’t it just be between the ears?  

Well, in our profession everything is pretty much between the ears, isn’t it?

You’ll know you’re on the right track when nobody comments on your audio improvements, because they could not be picked up.

It comes down to this.

Bad audio is an obvious earsore.

Quality audio is blissfully inconspicuous.

Seven Reasons to Hate Home Studios

by Paul Strikwerda in Articles, Freelancing, Studio 33 Comments

Just like desktop publishing changed the printing business, home studios have forever transformed the world of voice-overs.

If you enjoy hanging out in a stuffy, cramped, dark claustrophobic enclosure all day long, having a home studio is heaven.

Most clients seem to love it. They no longer have to hire an audio engineer and a director and pay for studio time. Theoretically, hiring voice talent with a home studio may save a lot of money, but it can come at a price.

Let me tell you about the downside of home recording.

1. $$$

At some point in your voice-over career you want to get rid of the egg crates and the moving blankets hanging from a pvc frame, and move into a real recording space. You have two choices: Prefab or DIY.

Even the cheapest Whisper Room™ will cost you more than three grand and this does not include shipping (these booths weigh as much as an elephant). The standard, single wall models usually don’t offer enough isolation. Double wall is your best and more expensive bet.

Most booths sound boxy and you will need bass traps to tame the “boominess.” Imagine putting these huge babies in your 3.5′ x 3.5′ space. If you enjoy breathing fresh air, add another $500 for a ventilation system.


Of course you can always build your own recording cave. This is not a project you can do on a Sunday afternoon. It might take many months and eat up all your spare time, energy and extra cash.

I designed and built my own booth, but I couldn’t have done it without the help of a contractor-friend. Thanks to him, I was able to keep the costs down. I couldn’t be happier with the result, but if I ever move, my studio stays and I’ll have to start from scratch.

2. More $$$

My Prized Possession

by Paul Strikwerda in Articles, Gear, Studio 34 Comments

What do the Vatican, the United Nations, the German Parliament, the BBC and my company Nethervoice have in common?

We all use top of the line microphones from a family owned business in the small German town of Gefell.

If you’ve never heard of Gefell and you enjoy European history, let’s travel back in time for a moment.

In 1943, Georg Neumann‘s main microphone laboratory in Berlin was hit by bombs and caught fire. To avoid more damage, Neumann and his technical director Erich Kühnast moved the entire company to Gefell where they continued their work in an old textile mill.

After Germany’s surrender, Gefell was occupied by the Americans and then handed over to the Soviet Union. In 1946 a number of Gefell employees returned to Berlin to establish a small workshop. This workshop eventually became Georg Neumann GmbH, the second Neumann company.

Kühnast and most of the original staff stayed in Gefell and continued to develop and build microphones. Neumann made Kühnast manager of the limited partnership Georg Neumann & Co. which was later nationalized by the German Democratic Republic (GDR). Despite the building of the Berlin Wall in 1961, the management of the two companies stayed in touch with one another.

In 1972, the GDR prohibited use of the Neumann trademark, and the East-German company was renamed VEB Mikrofontechnik Gefell.

After the Wall came down in 1989, Georg Neumann’s heirs reclaimed their share in the company and a new period of cooperation began. Here’s what’s remarkable. When the Neumann engineers took a closer look at the Gefell products that had been developed behind the Iron Curtain, they discovered microphone technology that was more sophisticated than some of that in the West.

After Sennheiser took over Neumann in 1991, Microtech Gefell -as it is now called- became an independent, privately owned company, known for hand-made, high-end microphones. (this overview is in part based on an article in Sound on Sound and on information on the Gefell website).


Fast forward to Tuesday, January 17th, 2012, the day I became the first person in America to own a Gefell M 930 Ts studio condenser microphone.

Out of thousands of microphones on the market, why did I pick this particular make and model?

I have to be honest with you: I didn’t pick this mic. It picked me. Or rather: I got lucky. Very, very lucky!

In my radio days I never paid any attention to the equipment I was using, but since I became master and commander of my own studio, things have changed. As a professional, I think it’s important to get to know the tools of the trade. 

Before I’m ready to make any type of investment in my business, I spend months doing research, reading reviews and talking to colleagues in the know. They make sure I don’t fall for the latest fad, and that when I finally decide on a new purchase, I invest in quality that will last for many years to come.

Any professional chef, musician or mechanic can tell you that well-made, reliable tools make the job a lot easier because they work with you instead of against you. Good tools can’t make an artist more creative, but they can inspire. Without them, he’s less able to realize his dreams. A great set of tools can take you to that proverbial next level.

It’s a cliché, but quality never goes out of style. It is remembered long after the price is forgotten.


As home studios are becoming the norm and more people are having a go at voice-overs, it’s increasingly important to distinguish oneself. It all starts with the way the voice is captured.

The quality of your sound is your signature.

Clients are sick and tired of having to put up with hiss, rumble, interference and echoes coming from inferior equipment recorded in so-called ‘professional’ booths set up in someone’s boudoir. By the sound of it, these spaces aren’t studios. They sound more like shacks. Radio shacks.

If you can’t provide clean, crystal clear audio, you should start a website where amateur VO’s can go forth, multiply and make a lot of noise. Why not call it VoiceRabbit (after the rabid growth I predict it will undergo)?

Alternatively, you could consult men like Dan Lenard, Dan Friedman, George Whittam or Mel Allen. They will set you up with the right gear and help you fine-tune your sound in less time than it will take you to learn the ropes through trial and error.

Although it never paints a complete picture, quality equipment does make a statement. When a client or agent sees you are using professional grade gear, they know you mean business and they have one less thing to worry about.

Imagine going to a wedding photographer to find out if he’s going to be a good fit for your big day, and the man pulls out a cheap point-and-shoot camera. Would you hire him? I don’t think so. Now, owning a Hasselblad 503CW does not make one a brilliant photographer, but that’s a different story.


In my quest for the best equipment, I spent many hours on Matt Mcglyn’s creation: www.recordinghacks.com. It’s an online magazine as well as the world’s most extensive database of a 1000+ microphones.

If you happen to be looking for a good podcasting mic for $200, recordinghacks has put them to the test. If you need the specs of the Manley Reference Gold tube condenser, look no further. Interested in a $60,000 ribbon mic shootout? You know where to go!

In 2011, recordinghacks gave away a new mic every month: a Cascade Fathead II, a Blue Yeti Pro, a Lauten Horizon et cetera. December’s prize topped it all: a brand new Microtech Gefell 930 Ts. This small, large diaphragm condenser was made with broadcasting and voice-over applications in mind.


In the first week of January, Matt Mcglyn said he had some good news for me: I was the lucky winner of the giveaway! It was unbelievable. What a start to the new year!

I want to thank Microtech Gefell GmbH for such a generous gift, and for their ongoing, uncompromising dedication to quality.

Matt Mcglyn deserves a big ‘thank you’ for creating such an excellent database and magazine, and for magically pulling my name out of his recordinghacks-hat.

As for the rest of you, I’m sure you’d like to know how my new mic sounds, and how it stacks up against other voice-over microphones. Well, it just so happens that I have written a review for recordinghacks, and you’ll find out for yourself why the Vatican has given its blessing to a small German company.

If there ever was one brand that has earned the right to capture the voice of G-d, it has to be Microtech Gefell!
