Microphone Buyers Guide: Things To know Before Buying A Microphone

Neumann MicrophoneMicrophones come in many different colors, not visually, but sonically. Think of microphones as audio lenses. There are lenses that are good for wide-angle shots, narrow and there are those that have a vintage feel to them.

The same is true with microphones. There are different pickup patterns, colors, and tones, etc. No mic/pattern combination works for everything.

Before buying a mic, there are a few things you need to consider. Your budget, what you plan on recording, and your current setup.

Mic specifications, Understanding the Lingo

Having a basic understanding of the lingo is good to have when looking for a mic. Most people just look at other studio’s gear lists or blow $1,000 on a mic without understanding what they’re buying into.

Frequency Response: Meaning the range of frequencies a microphone can pick up. A microphone with a frequency response of 80hz – 15khz wouldn’t be ideal for recording a bass drum but would be good for recording vocals

Response Curve: This is how the mic performs based on the frequency response. When you look at the curve, there with be peaks and dips in certain ranges indicating what the mic specializes in.

For example, vocals mics may peak a little more in the high-mid range frequencies, thus giving better vocal reproduction.

Sound Pressure Level: On the back of the mic packaging you’ll see this as SPL. The SPL is how quiet and loud of a signal the mic can capture and accurately reproduce.

Understanding Mic Polar Patterns

This is the mics field of view, that’s the best way I can describe it.

cardioid PatternCardioid: Mics with this pattern capture sound best when positioned directly in front of them while rejecting sounds coming from the sides and rear. This is the most popular pattern you’ll run into while shopping.

 

omni PatternOmni: Omnidirectional mics equally captures sounds from all directions. Great for capturing room tone and ambiance.

 

 

figure8 PatternFigure 8: This pattern allows for equal capture from both the front and rear positions of the mic. Also good for capture background and amb try sounds, much like the Omni pattern

 

 

supercardioid PatternSuper/Hyper Cardioid: Very similar to a cardioid mic, but more directional. It’s as if they zoom into the subject you’re pointing them at while rejecting sound from the side.

Also, unlike the regular cardioid, it doesn’t reject as much sound from behind making them a little difficult to work with.

Different Type Of Microphones

Dynamic Mics: Good for loud sounds and stage performances. They’re inexpensive require no additional power built like tanks

Shotgun Microphones: Typically hyper-cardioid and super-cardioid patterned. Excellent for voiceovers and field recording. These mics work similarly to a telescope by focusing on the sound in front of them and rejecting unwanted sound behind and on the side of them.

Condenser Microphones: Excellent for capturing detail in recordings. There was a time when condenser mics were too expensive for home studio musicians, but these days, they’re more affordable.

Side note – must be powered via phantom power

USB Microphones: Not ideal to a lot of professionals, but one can’t deny their growing popularity and ease of use. I find these microphones great for quick recording projects.

Microphone Diaphragm Sizes

Mics come in two sizes large and small diaphragm. Both capable of capturing great recordings, but slightly different.

Large Diaphragm: Lower self-noise, high sensitivity, lower dynamic range, a narrow frequency range and they produce an overall warmer sound.

Small Diaphragm: Higher self-noise, low sensitivity, and higher dynamic range. Where it shines is recording sounds with sharp transients.

Why Does All This Matter?

The more you understand about mics, the better decisions you’ll make when using them, and the better choices you make when shopping for a microphone. Too often I see people with a budget of $1000, and they don’t spend $800 of it on a microphone.

I’m not saying that the microphone isn’t worth the price, but it is worthless in the hands of someone who doesn’t understand it.

What You’re Recording Matters

If you’re recording ambiance, you’d want to use an Omni patterned microphone. If you’re recording sounds with sharp transients, you’d use a small diaphragm condenser microphone.

If you’re recording VO, you wouldn’t use a small condenser mic, you go for the large diaphragm. It’ll sound much better.

Don’t get caught up in the more money = better quality. It makes no sense to spend top dollar on a microphone if you won’t be recording in a top-dollar environment with top-notch gear.

Rode, Audio Technica, AKG…Do Brands Matter?

To an extent. Some brands are known for making great-sounding equipment others are known for just the opposite. Then you have brands that are known for creating quality gear at cheap prices.

This is where your budget and time come into play. Some brands make great-sounding microphones by mistake because there’s no quality control. If you’re willing to purchase, test and exchange until you get a good model it might be worth your time.

This happened to me with a Behringer condenser mic. It had a sound extremely close to U87. So, I purchased 5 more, and to my surprise, they all sound different – lack of quality control.

The same happened with a small condenser mic I purchased one from MXL. It had a really good sound to it, very close to my friend’s Rode NT5 at a fraction of the cost. Again, purchased more, this time, they all sound good.

Quick List Of My Favorite Microphones

Behringer B2: I know some of you were saying “blah Behringer”, but this is the mic I was talking about that sounds very similar to the U87. I’ve had this mic for 16 years, and it sounds wonderful.

Studio Projects B3: The most versatile mic I love this microphone because it comes with three polar patterns Cardioid, Omni, and Figure 8. I use this for all sorts of recordings; VO, drums, and SFX.

Rode NTG1: My first shotgun mic, not the best, but it does get the job done, and it’s relatively inexpensive. Especially when compared to other shotgun microphones.

ATR2100 USB: This Mike made it on my list because it’s a USB mic that can be powered via USB and 48v meaning it has an XLR input. I like this mic because of the sound quality, it’s very similar to the rode podcast and it’s under $60.

Conclusion

There are a lot of sites that offer great reviews on microphones so do a little research. You can also rent time in a studio… One or two hours would be adequate time to test out different types of microphones.

There are also services out there that will allow you to rent music gear for dirt cheap. From there you can again, test and decide if the mic is something you want long term.
