Looking to improve audio quality? Smart move.
I started working with podcasts because I was an avid podcast listener. I would be listening to a conversation, hanging on every word, and then it would happen …
The guest would bump his mic at the exact moment when he said the one thing I wanted to hear, and I’d miss out.
Our content should connect and engage, not frustrate and push away.
Since I run a podcast production company, I’ve learned that most people think any sound problem can be repaired with the simple twist of a knob. If only that were so.
Do you know how to avoid the most common audio production pitfalls that distract your listeners from their favorite podcast topics?

Quality audio defined
Audio quality can be as subjective as Picasso’s art in a museum. One person says it’s brilliant … the next walks away scratching their head.
Let’s start with what quality audio is not.
You can tell audio needs to be improved when you hear:
- Room reflections (echoes from the recording room)
- Microphone handling, bumping sounds
- Other foreign sounds: animals, lawnmowers, keyboard clicks, etc.
- “Plosives” (the explosive sound consonants make when spoken into a microphone)
- Extreme audio processing (audio effects that create an unnatural sound)
On the other hand, quality audio can be defined in one word: natural.
Quality audio sounds as if you’re talking around a kitchen table or with a client in your office. Your sound should be a “welcome mat” that invites the listener in for what feels like a face-to-face conversation.
How to record high-quality audio
How do you accomplish that? How do you improve audio quality? Here are 10 tips that will help you produce the “welcome mat” experience.
1. Value your listeners
Podcasts and blogs are similar.
In the same way that good website design helps attract and keep blog readers, quality audio attracts and keeps listeners around.
Quality audio isn’t about making you sound good, it’s about engaging your audience — just like good about me pages.
2. Invest in the right microphone
You knew this one was coming.
Microphones are the most important element of quality audio, but podcasters don’t need fancy, expensive ones.
If you record a monologue or interview-style podcast in an office or room in a home, a dynamic microphone is what you need. Other microphones work, but they can require more resources to coax out good sound.
Want some recommendations? My favorites are:
- Audio-Technica 2100: a great USB microphone at an amazing price
- RE20: the most popular microphone for radio for decades
The microphones listed above will produce good sound, but remember that choosing a microphone to improve audio quality is mostly about personality and taste. You need to ask yourself if the microphone is right for you, your voice, and your brand.
One way to answer the “which is best for me” question is to book a session at a professional recording studio and try out a variety of microphones. Take those recordings and get some feedback.
Between the engineer at the studio and your friends and family, you should be able to find a clear winner. Also, keep your target audience in mind. Does the microphone help communicate who you are? Does it match the tone your audience needs to hear?
Here are a couple guidelines about microphones to avoid:
- The headset microphone that came with your smartphone. While those are great for appearing live on Facebook, they’re not ideal for podcasting.
- A condenser microphone. They’re made for the acoustics in big, fancy, recording studios. Unless you’re planning to build a recording booth in your garage, leave these microphones in the store.
3. Use a microphone stand
Some podcasters like to record with the microphone in their hands. Unless holding the mic is absolutely necessary, avoid that technique.
Another common microphone-stand mistake is connecting it to a surface your hands or feet easily touch. If it’s a desk-mount stand, try connecting it to a nearby piece of furniture that’s not touching the desk. Or, if it’s a floor-mount stand, make sure the feet rest on carpet or padding.
Otherwise, the small movements you make during recording can transfer up the stand and into the microphone, which produces distracting sounds.
4. Find a great place to record
Before you start to figure out how to get the best audio quality from your mic, you need to find a great place to record. This item alone is a quick win for good sound.
Before you record, double-check that your room doesn’t reflect your voice back into the microphone. Carpet, furniture, wall decorations, and non-parallel walls all help calm the reflections. Trying a smaller room, or even a closet, is often easier than acoustically treating your current recording space.
You should also keep outside noises to a minimum. Common offenders are:
- Phones and other electronics
- Open windows
5. Speak near the microphone
Even though you’re looking to improve audio quality, nearly everyone shies away from the microphone. Don’t.
Even a slight distance from a mic makes you sound like you’re in a cave.
You’ll want to nearly kiss it. Make it your friend, and it will make you friends as you build your audience with audio content marketing.
6. Set up a pop filter
The downside of speaking near the microphone is that it causes “plosives.”
“Plosives” are simply the air from consonant sounds disrupting the sensitive components of the microphone.
The pop filter, a screen that goes around or in front of a microphone, is a tried-and-true solution. Expensive or cheap, they’re all about the same.
7. Select an audio interface
Although many recommend using a mixing board, I’ve found that the never-ending knobs create more headaches than freedom.
The simplest solution is to plug your microphone into an audio interface, which converts your analogue microphone sound into digital, so your computer can understand it.
As a side note, even if you’re using the Audio-Technica 2100, it’s still a good idea to utilize an audio interface instead of the USB connection. It produces a much more detailed and clear sound.
My current audio interface favorites are:
8. Record separate tracks
Take advantage of multiple tracks to make sure every voice has its own separate recording.
With a two-person interview, it’s easy to pan the host to the left track and the guest to the right track. If your guest joins you via video chat, capturing a separate track of their local recording is helpful.
In the past, this was only possible if the guest was well-versed in audio or recording in a radio station. Thankfully, technology has advanced.
One of my favorite tools is Zencastr. It records via a web browser and uploads the best audio possible to your dropbox account.
9. Back up your recordings
Some people prefer to avoid a computer and record into a small recording device. I often do this myself, after having one too many recording sessions ruined by computer glitches.
I know of an author whose power went out while he was recording an audiobook. He lost four hours of recorded audio!
You can avoid that exact situation by recording into an external recorder. Or better yet, record into a computer for convenience and add an external recorder as a backup, just in case.
One of the fastest ways is to simply use an XLR splitter, which will split the signal into both the audio interface and the external recorder. If you have multiple sources, running an output from the interface into the recorder is a great way to use it as a secondary backup.
A couple external recorder favorites of mine are:
- Tascam DR-100mkIII
- Sound Devices MixPre-3
10. Edit and produce your content
While creating a good recording is the bulk of what’s involved in producing a podcast, quality editing and production wraps up the improve-audio-quality package.
If you have audio experience, go for it, but if you’re hesitant, grab someone who’s spent some time in the field. Even if you don’t hire a producer who specifically works with podcasts, their wisdom can help ensure you avoid expensive mistakes and end up with a quality product.
For those producing podcasts on their own, check out Auphonic. Auphonic has turned years of professional audio experience into an inexpensive piece of online software. Their specialty is leveling audio and removing background hiss and noise, an audio producer’s two most important jobs.
Bonus tip: loosen up
Before you record, have some fun: watch a cat video, laugh a little, do some vocal warm-ups.
Think about the person you’re aiming to help and the problem you can’t wait to solve for them, just as if you were writing copy.
Better recordings strengthen your message
Remember, audio equipment exists to enhance your message.
Who you are and what you have to say is invaluable … the gear is just a method of transporting the gold.
