There are a lot of ways to record podcast audio: you could just use the built-in mic in your computer, or plug in a budget USB microphone. 

But when you’re ready to step up to a high-quality dynamic or condenser mic and get professional quality sound, you’re probably going to need a digital audio interface. 

Rather than just cover the basic audio interfaces, like the Zoom H6 and the Rodecaster Pro, we took another approach to creating this guide. We chatted with Los Angeles-based producer, composer, and recording engineer Dave McKeever, who has used countless audio interfaces over his 25 years in the recording business. 

Here are some models he recommends whether you’re starting a podcast or improving on an existing one. You can find most of these interfaces for sale on Amazon.

What is an audio interface for podcasts?

An audio interface is a physical device that transforms analog audio signals from a microphone or an instrument input into digital signals that can be processed by a computer. A podcast audio interface is no different than a digital audio interface you would use for recording any kind of audio.

Audio interface components 

A quality audio interface typically includes the following components:

  • Inputs. Most audio interfaces include ports for 3-prong XLR inputs as well as ports for 1/4-inch cables. Some may offer inputs for 1/8-inch plugs as well, but that’s less common. XLR is the gold standard for mic inputs because it has a balanced signal that cuts out background noise and hiss.
  • Gain knobs. Next to each mic input, you should see a knob that controls the amount of gain you add to an audio signal. This can be great for boosting mics with high impedance, meaning they need an external source of power to produce a strong audio signal. (Some of the best microphones for podcasts, like the Shure SM7B, have high impedance and have to be driven by a powerful preamp to boost their volume and capture the full range of audio frequencies.)
  • PAD. A passive attenuation device (known by the acronym PAD though usually spelled in lower-case letters as “pad”) is a mechanism that limits the signal coming through a microphone and into your audio interface. If you have an overly loud signal coming through your microphone, it will cause distortion and clip the high frequencies. To fix that, you can cut a certain number of decibels by flipping on the pad. This can improve overall podcast sound quality on ultra-high gain audio inputs.
  • Phantom power. A condenser microphone requires external power to maintain a flow of electrical current. Most audio interfaces can provide this current, which flows from a power source (like your computer) through the interface and into the microphone using an XLR cable. This kind of current might be labeled as phantom power on your interface, or it might be labeled +48v. In both cases, you activate this current by pushing a button or flipping a switch.
  • Digital outputs. Most digital audio interfaces are USB interfaces, which means they connect to a computer using a USB cable. There are also audio interfaces specifically designed for the Apple iPhone and iPad. Because these devices use a proprietary Lightning port, USB audio interfaces don’t natively connect to them. Fortunately, companies like Apogee make iPhone-specific digital audio interfaces, and these work with Lightning ports.
  • Analog audio outputs. If you want to directly monitor your audio recordings without involving your computer’s sound card, you can use the analog audio outputs on your audio interface. This comes in handy when you want to plug in big, powerful monitor speakers instead of using small computer speakers. These output ports are usually 1/4-inch, but some audio interfaces use RCA cables or even XLR cables.
  • Headphone output. Last but not least on the inputs/outputs list is a headphone output for privately monitoring podcast sound quality. Headphone outputs have their own volume control that won’t affect other outputs, whether those are USB, XLR, or 1/4 inch.

Do I need an audio interface for podcasting?

You don’t need an audio interface for podcasting, but it’s recommended by the pros. A digital audio interface is the link between your podcast microphone and your audio recorder. In most cases that audio recorder will be a computer running digital recording software.

Digital audio interfaces translate analog audio, like your spoken voice, into the digital language of computing. Without it, you have no way to get high-quality sound onto your computer for editing. 

Technically you can avoid buying a digital audio interface if you have a microphone with a USB output, which can plug directly into a computer, or a Lightning output, which can plug directly into an iPhone or iPad. Most of the best-quality microphones use XLR outputs, however, and these won’t plug directly into a computer; you need an interface to use them.

Things to look out for before buying an audio interface

Here are Dave’s top 5 criteria to consider when shopping for an audio interface.

  • Connectivity. Make sure your audio interface can connect to all your digital devices. USB is the standard, but some audio interfaces connect to Apple’s proprietary Lightning plug for iPhone and iPad.
  • Number of inputs. Depending on your recording needs, you might only need one single input. Dave suggests you future-proof by picking a device with at least two inputs — you never know when your solo podcast will need a cohost.
  • Power needs. Can you power your interface using bus power and a USB cable? Or do you need to plug it into a wall socket, which will provide more gain but also make the device less portable?
  • Sample rates. “Higher sampling rates equal better resolution,” Dave says. “As long as your interface does 48k, you’re probably pretty good. Recording in 48k is the industry standard. You can get into higher sampling rates, but your file size increases.”
  • Bit depth. “Higher bit depth gives you more flexibility down the line,” Dave says. “Bit depth means that you have a little more ability to turn up the volume later and not add a bunch of noise and distortion. 24-bit/192 kHz is the industry standard and all new audio interfaces will record at this level.”

7 accessories to complete your podcast setup

Here’s a podcast equipment checklist to consult as you build your podcast recording setup.

  1. Microphone. Whether you choose a dynamic microphone or a condenser microphone, pick a unit that does well with the human voice. The other components of your podcast won’t matter if your audio isn’t clear, articulate, and free from unwanted distortion.
  2. Microphone stand. A good mic stand frees up your hands and keeps the mic steady throughout the recording, which reduces unwanted noise.
  3. Microphone cable. A mic cable (typically an XLR cable) connects the microphone to the audio interface.
  4. Pop filter. A pop filter is a thin membrane of fabric that sits in front of the microphone and prevents plosives (like the letter “p”) from creating popping sounds in the recording.
  5. Audio interface. Choose an audio interface based on the criteria we’ve laid out above.
  6. Headphones and speakers. Headphones and speakers let you monitor your recordings while they happen. You’ll also use them to listen back as you edit the recording.
  7. Computer with your choice of DAW. Last, but certainly not least, you need a place to edit your recorded audio. For nearly all podcasters, that will be a computer running a digital audio workstation (DAW). Popular DAW brands include ProTools, Adobe Audition, Logic Pro, Ableton Live, and, of course, Descript.

Do I need an audio interface for podcasting?

You don’t need an audio interface for podcasting, but it’s recommended by the pros. A digital audio interface is the link between your podcast microphone and your audio recorder. In most cases that audio recorder will be a computer running digital recording software.

Digital audio interfaces translate analog audio, like your spoken voice, into the digital language of computing. Without it, you have no way to get high-quality sound onto your computer for editing. 

Technically you can avoid buying a digital audio interface if you have a microphone with a USB output, which can plug directly into a computer, or a Lightning output, which can plug directly into an iPhone or iPad. Most of the best-quality microphones use XLR outputs, however, and these won’t plug directly into a computer; you need an interface to use them.

Things to look out for before buying an audio interface

Here are Dave’s top 5 criteria to consider when shopping for an audio interface.

  • Connectivity. Make sure your audio interface can connect to all your digital devices. USB is the standard, but some audio interfaces connect to Apple’s proprietary Lightning plug for iPhone and iPad.
  • Number of inputs. Depending on your recording needs, you might only need one single input. Dave suggests you future-proof by picking a device with at least two inputs — you never know when your solo podcast will need a cohost.
  • Power needs. Can you power your interface using bus power and a USB cable? Or do you need to plug it into a wall socket, which will provide more gain but also make the device less portable?
  • Sample rates. “Higher sampling rates equal better resolution,” Dave says. “As long as your interface does 48k, you’re probably pretty good. Recording in 48k is the industry standard. You can get into higher sampling rates, but your file size increases.”
  • Bit depth. “Higher bit depth gives you more flexibility down the line,” Dave says. “Bit depth means that you have a little more ability to turn up the volume later and not add a bunch of noise and distortion. 24-bit/192 kHz is the industry standard and all new audio interfaces will record at this level.”

7 accessories to complete your podcast setup

Here’s a podcast equipment checklist to consult as you build your podcast recording setup.

  1. Microphone. Whether you choose a dynamic microphone or a condenser microphone, pick a unit that does well with the human voice. The other components of your podcast won’t matter if your audio isn’t clear, articulate, and free from unwanted distortion.
  2. Microphone stand. A good mic stand frees up your hands and keeps the mic steady throughout the recording, which reduces unwanted noise.
  3. Microphone cable. A mic cable (typically an XLR cable) connects the microphone to the audio interface.
  4. Pop filter. A pop filter is a thin membrane of fabric that sits in front of the microphone and prevents plosives (like the letter “p”) from creating popping sounds in the recording.
  5. Audio interface. Choose an audio interface based on the criteria we’ve laid out above.
  6. Headphones and speakers. Headphones and speakers let you monitor your recordings while they happen. You’ll also use them to listen back as you edit the recording.
  7. Computer with your choice of DAW. Last, but certainly not least, you need a place to edit your recorded audio. For nearly all podcasters, that will be a computer running a digital audio workstation (DAW). Popular DAW brands include ProTools, Adobe Audition, Logic Pro, Ableton Live, and, of course, Descript.
