Here are 8 of the most important technology pieces you’ll need to get your podcast up and running in no time flat.
Microphones, whether you know it or not, are essentially transducers, meaning they convert one form of energy into another. Microphones take acoustical energy and convert it into electrical, but the way this process happens changes depending on which type of microphone you’re using. Here’s a closer look at the three main kinds of microphones, and how they convert live sound into electrical signals:
Empire Sound Studio, located near Dallas, Texas, has recorded some of the biggest acts in music in nearly every musical genre — and one of their favorite mic brands to use in the studio is MXL. MXL Microphones got a chance to talk to Alex Gerst, engineer and founder of Empire Sound Studio, about how the studio got its start and why MXL Mics have remained mainstays in the mic locker throughout the years.
The multiple Grammy-winning producer and composer has been a big fan of MXL Mics for more than a decade. Wright first gained notoriety for arranging strings for smash hits like Michael Jackson’s “Don’t Stop ‘Till You Get Enough” and “Rock with You,” and he continues to work with top pop artists today, recording strings for Justin Timberlake’s 20/20 Experience album and Ty Dolla $ign’s Free TC. Here’s more on how MXL plays a big part in this music legend’s career.

Condenser mics are best known for their sound sensitivity, wide frequency response, and phantom power requirements, but what’s going on inside to give them that signature sound? Let’s take a closer look:
A question our technical support gets all the time is, “What microphone is best for broadcasting and podcasting?” The answer is, any microphone can amplify a voice. That’s easy. But does it sound natural? Is your deep voice too muddy? Is the sound too bright? There are some subtle differences with broadcast mics that make speech sound clear and smooth, the way it should over the radio. You want to select a true broadcast microphone for your radio show or podcast, especially if you have one of those deep radio voices.
When you hear a memorable guitar riff, you’re probably not thinking of how it was recorded…where the amp sat, was it on a carpeted floor, was the microphone two inches or ten inches away. But it’s these details that contribute to the sound you hear on the recording. So how do you capture the sound of an electric guitar?
First of all, you want to record the amp. While the electric guitar can certainly be recorded directly, there are times when there is simply no substitute for the sound of a real amplifier. Guitar amps have particular gain stages that facilitate the popular “crunch” guitar sound. While digital modeling and processing systems certainly have their place, they may not have the same level of realism as the sound from an amplifier. A small guitar amp can be just as effective for this application as a stack, because you don’t necessarily need to “crank” the volume. Instead, you want to increase the amp’s initial gain to achieve the desired amount of overdrive.
Typically, a guitar amp is close mic’ed to achieve the highest direct sound. Placing the microphone roughly 4 inches from the grill, aimed directly at the center of the loudspeaker will produce the most “edge” to your sound. If you move the mic further away, it takes the edge off the sound. It’ll be a bit mellower.
Now, if you’re going to put a microphone super close to an amp, it better be able to handle some high SPLs (sound pressure levels). It doesn’t necessarily have to be a dynamic mic – a condenser or two can do the job. A good instrument mic can perform well on a variety of instruments, including a guitar cabinet.
Distance from the source isn’t the only thing affecting the sound. By angling the microphone slightly off axis and towards the wall, you can add more “room sound.” Experimentation is a key factor in achieving the sound you are looking for. You might put one mic close to the cabinet and one several inches way. You’ll target the cabinet but you’ll also pick up the cabinet sound as it’s reflected in the room.
A ribbon mic might also give you the mix of guitar and room sound you’re looking for. The figure eight pattern picks up sound to the front and back of the mic without any creative placement. It’s what ribbon mics are made for.
Placement of the amp is another important factor. If the amplifier sits on a carpeted floor, you are more likely to reduce the amount of brightness in the sound. Similarly, elevating the amplifier off the floor may result in a loss of low-end. If you’re looking for a big reverberant tone, placing the amp and microphone in the bathroom is another popular technique. The hard tiles and other reflective surfaces can do wonders for a dull sound. In this case, move the microphone back a few feet from the loudspeaker and crank it up!
Recording audio is all about getting the sound you want. Garage band or singer/songwriter? Rock anthem or wedding ballad? “Enter the Sandman” or “Faithfully”? Determine your desired sound and then adjust your mic and amp placement until you get it. There’s no wrong answer!
