Condenser Microphone: Buyer Guide to Pick The Best One

What is a condenser microphone?

Condenser microphones, also known as ‘capacitor mics,’ are a type of microphone that converts sound waves into audio signals through capacitance. 

A condenser mic's membrane is suspended close to a solid metal plate. There is a current flowing across these two components. When sound waves hit the membrane, they cause it to move back and forth, thus the fluctuating distance between it and the metal plate. This causes the capacitance to change, and this is how the mic interprets the sound waves into audio. 

Condenser mics require an external power source to work - often referred to as ‘phantom power.’ 

What's the difference between condenser and dynamic microphones?

The ultimate function of condenser and dynamic mics is the same, but there are some key differences that you should be aware of. 

They convert sound into audio differently 

Firstly, dynamic mics convert sound into audio using electromagnetism instead of capacitance. 

Power source

In addition, while condenser mics need a power source to work, dynamic mics don’t. 

Sensitivity

Condenser mics are generally better for capturing delicate, nuanced sounds and higher frequency sounds. Dynamic mics are better suited to live environments with louder and stronger sound sources such as drums. Meanwhile, condenser mics perform best in a studio environment. 

Durability 

Finally, condenser mics tend to be far more delicate and susceptible to damage if not handled carefully because of their construction. By contrast, dynamic mics are robust and durable, even if roughly handled.

Large versus Small Diaphragm Condenser Mics

Although the physical difference between a large and small diaphragm condenser mic might be noticeable, let’s look at how this affects the mic's functionality. 

Larger diaphragms have less self-noise 

Large-diaphragm condenser mics typically produce less self-noise, which is a big plus for conserving the high-quality of your audio. 

Larger diaphragms are more versatile 

Large-diaphragm condenser microphones will do well in just about every application. This doesn’t necessarily mean they’ll give you the exquisite sound quality of a small diaphragm mic, but what it does give you is flexibility in how you use your mic. 

Smaller diaphragms produce higher-fidelity sound 

Smaller diaphragms are more accurate, producing higher-fidelity sound than large-diaphragm mics. 

Smaller diaphragms have a broader frequency response 

In addition, small diaphragm condenser mics boast a far more comprehensive frequency response range. 

Smaller diaphragms have a consistent pickup pattern 

A consistent pickup pattern refers to how consistently a mic performs as you rise through the frequencies. A consistent pickup pattern is a cornerstone of a good quality mic. 

What are the Benefits of a Condenser Mic?

Compact 

Condenser mics tend to be small and highly portable. But don’t let that fool you. These mics seriously pack a punch in terms of audio quality. 

Can pick up delicate sounds 

Condenser mics are known to pick up delicate and nuanced sounds far better than their dynamic counterparts. 

Can pick up high-frequency sounds 

Condenser mics perform much better at picking up higher frequency sounds. 

How to Choose the Best Condenser Mic

When it comes to choosing your condenser mic, the most significant piece of advice is to find a mic that works for you. If the highest recommended mic just doesn’t do it for you, that’s ok. Your voice and specific setup will mean you have particular needs compared to another podcaster. That said, there are some common factors to keep in mind. 

Your Budget

Before you start browsing mic options, you’ll need to settle on how much you’re willing to spend on your microphone. Don’t worry, even if you’ve got a strict budget, you’ll be able to find a mic that works well for your needs. 

Microphone Applications

Next, you’ll need to think about your needs, wants, and how you will be using this microphone. What kinds of sounds will you be recording? And in what kinds of environments? If you’re solely a podcaster, your primary focus will be vocals. However, if you’re also an instrumentalist, for example, you may want to look into whether your chosen mic works well with your instrument of choice. 

Connectivity 

If you’re looking for a plug-and-play mic, you’re most likely looking for a USB condenser mic. If you’re a stickler for quality and have the money to spend on an audio interface and xlr cable, however, then you’ll be able to look at XLR condenser mic options too. 

Size of the diaphragm

As we saw earlier, the size of your mics diaphragm can impact its performance at higher frequencies and how accurate the audio it produces is. 

The Polar Patterns

Another huge consideration is your mic’s polar pattern. You’ll have to choose between cardioid, super-cardioid, bi-directional, and omnidirectional. All of these are more or less suitable, depending on what you’re recording and where. 

Cardioid

A cardioid pickup pattern is named for its heart shape. A cardioid mic will predominantly pick up sound from in front of the mic. A hyper-cardioid mic is essentially a more extreme version of this. Hyper-cardioid mics do the same, blocking out any other external noise more effectively. 

Bi-directional 

Bi-directional mics pick up sound from two directions: the front and back of the mic. 

Omnidirectional 

Omnidirectional mics pick up sound from 360 degrees. 

The Frequency Response

The frequency response indicates what range of frequencies your mic can pick up on. It also tells you how your mic performs at any given frequency. For example, one mic might perform better for highs versus lows or vice-versa. A typical frequency response range goes between 20 and 20,000 Hz, although it varies depending on the mic and maker.

Best practices for condenser microphones

• Use the correct mic positioning: Your mouth shouldn’t touch your mic. It’s best to position your mic at least 2-6 inches away from your mouth and angled at about 45 degrees to your face. We suggest playing around with positioning until you're happy with how recordings sound. 
• Record in a soundproof room: Condenser microphones are highly sensitive to noise, so even a background fan can interfere with recordings. It’s best to record in a space without any background noise. Learn how to build your own soundproof studio with our guide.‍
• Use compatible and studio-quality recording software: It doesn’t help if you have a top-quality mic with software that can’t capture high-resolution audio. Luckily with Riverside, it’s easy to capture lossless audio at up to 48kHz audio resolution! Learn more, or start recording professional audio seamlessly!
