Everything you need to know about microphones in 2024

The world of microphones can be daunting. Whether you’re looking to start a podcast, sing the national anthem, stream on Twitch, or just sound better on Zoom calls, there’s an overwhelming array of options out there. But here’s the thing: you don’t need to be an audio engineer to understand the basics.

Let’s break it down.

The big three: your microphone essentials

At their core, microphones do one thing: convert sound into electrical signals. But how they do it? That’s where the technology and uses get interesting.

Dynamic mics: the workhorses

Think of these as the Toyota Camrys of the audio world – reliable, hard to break, and perfect for rough environments. Dynamic mics (the mic you’ve definitely seen at every concert) uses electromagnetic wizardry to handle everything from screaming vocalists to cranked guitar amps without breaking a sweat. No external power needed.

Condenser mics: the studio stars

These are the precision instruments of the audio world. They need “phantom power” (basically, electricity through the mic cable) to work their magic, but what you get is crystal-clear audio that captures every nuance. Typically, you’re using these to mic up instruments and “warmer” vocals.

Ribbon mics: the vintage virtuosos

Here’s where things get delicate. Ribbon mics use a thin strip of metal to capture sound in a way that’s eerily close to how our ears work. They’re fragile (and often expensive), but nothing else quite captures that warm, natural sound. If you’ve seen video of old-school crooners like Frank Sinatra he’s using a ribbon mic.

USB mics: plug-and-play simplicity

The Blue Yeti has become synonymous with easy audio for a reason. These mics skip the complicated audio interfaces and plug straight into your computer. Perfect for podcasting or streaming without the technical headaches.

The simplicity of just plugging in a USB cable make these mics ideal for video conferencing uses as well. Yes, you can certainly use a built-in mic that came with your laptop. But if you want to really shine in your next call, upgrade the audio with a mic that brings your voice front and center.

Lavalier mics: the invisible performers

Those tiny mics you see clipped to speakers’ shirts? They’re engineering marvels that pack professional sound into a package smaller than your thumb. This is more a form factor designation and not audio capture.

Lav mics can also be used in live theater production. For these, they are typically hidden in the hair or in the costumes. Giving performers the ability to be heard throughout the theater or space is a huge benefit.

Shotgun mics: the focused listeners

These are the snipers of the audio world. Point a Sennheiser MKH 416 at your subject, and it’ll capture clear sound while ignoring almost everything else. You have certainly heard these mics, even if you’ve never seen one. Nearly every TV and movie product leverages shotgun microphones. This allows the actors to perform their lines without have individual mics.

The bottom line

Here’s the reality: there’s no one-size-fits-all microphone. A mic that’s perfect for recording whispered videos would be terrible for capturing a metal concert. But understanding the basics means you can make an informed choice based on your needs.

For most people’s everyday use, a solid USB condenser mic hits the sweet spot between quality and convenience. But if you’re planning to record in noisy environments or need something more robust, a dynamic mic might be your better bet.

The good news? Microphone technology keeps getting better and more affordable. Whether you’re spending $100 or $3000, there’s never been a better time to upgrade your audio game.
