What is a Podcast Interface?
A podcast interface is a ‘translation’ device that is the middleman between your microphone and your recording device. It translates analog audio captured by your podcast microphone into a unified signal for your laptop or editing software to read.
A podcast interface often makes sense if you need to:
- Consolidate analog sound into a single audio input
- Stream audio to your computer, tablet, or phone
- Edit audio on a DAW
However, you may want to consider a podcast mixer if you want to:
- Mix multiple audio sources
- Capture audio with an on-board SD card
- Process & mix audio directly on the device
Do you need an audio interface for your podcast? Not necessarily if you’re recording directly into an app like Zoom or Riverside using a USB or built-in mic. However, if you want the highest-quality sound for a more professional and polished presentation, it’s a must-have piece of podcasting equipment.
Not all interfaces are designed alike, and you’ll get different levels of quality depending on the option you buy. That’s why you need to consider your options carefully — including the differences between standalone and multifunction
Types of Podcast Interfaces: Standalone vs. Multi-Function
As mentioned, there are two different types of podcast interfaces: standalone devices and multi-function devices. Both devices are equipped for capturing audio, although they do so in somewhat different ways.
Let’s start with this helpful comparison chart:
| Standalone Podcast Interface | Multi-Function Podcast Interface | |
| SD cards | ❌ | ✔️ |
| Best for desktops | ✔️ | ❌ |
| Mixes audio | ❌ | ✔️ |
| Needs separate recording device | ✔️ | ❌ |
So, what’s the main difference between both types of interfaces?
Standalone interfaces require a recording device. This could be your computer or tablet, along with whatever podcast recording software you prefer. It may be a decent option for office-based podcasters who don’t plan to travel to guests or capture recordings in the field.
In contrast, multi-function interfaces do not need a separate recording device. You can mix, capture, and even edit audio directly from your interface. These are great options for busy or traveling podcasters who must capture, edit, and publish shows on short notice.
Not sure which type of interface makes the most sense for your show?
Keep reading below to see the full breakdown of both types (and their top models).

Let’s start by comparing the best standalone podcaster interfaces below.
Standalone Podcast Interfaces
As discussed, standalone podcast interfaces require a dedicated recording device. In exchange for the simplicity, they’re typically more cost-effective than multi-function interfaces.
Let’s start with one of the most popular standalone interfaces:
Focusrite Vocaster One and Two: Best Podcast Interfaces for Live Streaming
| Pros | Cons |
| 1 and 2 input options | Nearly all cables sold separately |
| Bundled software included | No mics or headphones included |
| Stream audio directly to camera | Software eventually expires |
There are two popular kinds of Focusrite Vocasters: the Vocaster One and the Vocaster Two. Both of these options come with editing and hosting software, XLR mic inputs, and podcast camera outputs for video podcasts. You can also purchase Focusrite interfaces in equipment bundles for all-in-one hardware and software packages, although be advised they’re more expensive and might not make sense for established podcasters.
Unfortunately, the software you get with a Focusrite Vocaster expires after just six months. Plus, you need to purchase most of your connector cables separately — it doesn’t even come with TRRS/TRS cables. This might be frustrating for podcasters on a budget, especially after spending nearly $250 USD.
Focusrite Vocaster features
- 1-2 XLR mic inputs
- Camera input option
- Bluetooth connectivity
- Bundled software (Hindenburg LITE; 6 months of Acast Influencer; 6 months of Hindenburg PRO)
Focusrite Vocaster pricing
- Focusrite Vocaster One: $149.99 USD
- Focusrite Vocaster Two: $249.99 USD

ZOOM U-44: Best Podcast Interface for Interchangeable Podcast Microphones
| Pros | Cons |
| Compatible with interchangeable mics | Phantom power only on 2 outputs |
| Supports instrument connections | No more free software available |
| Competitive price point | No ability to record audio |
The ZOOM U-44 is a well-suited option for mobile podcasters who are always on the go. Each interface comes with two XLR inputs and is also compatible with interchangeable mics (think shock-mounted stereo microphone or the SGH-6 shotgun microphone capsule.
Unfortunately, the ZOOM U-44 comes with its fair share of quirks, including limited phantom power for two outputs only. It also no longer comes with free software inclusions — the company discontinued production in 2021.
ZOOM U-44 features
- 2 XLR mic inputs
- Two MIDI I/O jacks
- iPhone or iPad hookup
- 10-pin connector for interchangeable input capsules (mics)

PreSonus Revelator io24: Best Podcast Interface for Included Software Bundle
| Pros | Cons |
| Works on all major platforms | May have strong room tone with gain |
| Comes with editing and hosting software | No ability to record unprocessed and processed audio versions |
| Wirelessly controllable with UC Surface 2 App | Cannot record audio directly on the interface |

Each device comes included with podcast editing software, as well as an audio library tool for building the soundscape of your show. You can even wirelessly control your device by downloading the free UC Surface 2 app.
Just remember that the PreSonus Revelator is a standalone podcast interface, which means you can’t record directly to your device or capture onboard audio. Plus, your software subscriptions don’t have everything you need — you’ll still need to get podcast editing software.
PreSonus Revelator io24 features
- 2 XLR mic inputs
- Onboard DSP
- MIDI in and out
- Bundled software (Studio One Artist; Ableton Live Lite; Studio Magic Suite)

Multi-function Podcast Interfaces
As mentioned, multi-function podcast interfaces act as interfaces, mixers, and recorders. They’re an all-in-one tool for capturing podcast audio — provided you’re willing to pay for them.
Here’s what you can expect from the best multi-function podcast interfaces:
TASCAM Mixcast 4: Best Podcast Interface for On-Board SD Cards
| Pros | Cons |
| 4 mic inputs | Adjusting the sound pad requires TASCAM Podcast Editor (software) |
| Mix Minus feature for call-ins | No additional software bundle |

Your audio is captured and saved to built-in SD cards, with support for up to 512 GB SDXC.

As you can imagine, this power comes at a price: the ZOOM PodTrak P8 starts at $550 USD. It’s also somewhat limited despite its cost. For example, its samples are of lower quality compared to other interfaces.
ZOOM PodTrak P8 features
- 6 mic inputs
- 3 remote interview options

- Adjustable sound pads (bank up to 36)

Maonocaster E2: Best Podcast Interface for Podcasters on a Budget
Alt: Here’s why the Maonocaster E2 is the best podcast interface for podcasters on a budget.
| Pros | Cons |
| Highly competitive price point | No software bundle |
| Equipment bundle | No headphones included |
| 12-month warranty | No support for USB microphones |
Sometimes referred to as the AME2A, the Maonocaster E2 is one of the most cost-effective equipment bundles on the market. In addition to the mixer itself, you also receive earphones, a microphone, and a mic stand. Each purchase has a shock mount and pop filter for additional recording quality.
Keep in mind that Maono’s equipment isn’t always high quality — you only get earphones, not headphones, after all. You also won’t have access to additional software bundles, although the below-average price point may leave wiggle room for additional purchases.
Maonocaster E2 features
- 2 mic inputs
- 3 preset audio effects
- 11 sound pads (customizable)
- Equipment bundle (earphones, shock mount, metal pop filter, PM320T microphone, and mic stand)

Honorable Mentions for the Best Podcast Audio Interfaces

- ZOOM PodTrak P4: Best podcast interface for handheld recording.
- Squarock Equipment Bundle: Best podcast interface for extreme budgeting.
How to Choose the Right Audio Interface for Your Podcast
Comparing the differences between audio interfaces can feel like drinking from a fire hose. Thankfully, making the right decision doesn’t have to be difficult — provided you put the most important factors first.
Here are some questions to narrow down your shortlist:
- How many guests do you have on your show? If it’s just you and a call-in guest, an interface with one input may be enough. However, you may need an interface with two or more inputs if you have a co-host or in-person guest.
- Is your recording room soundproofed? If so, you may be able to get away with cheaper mic preamps. If you don’t have a soundproofed room, or if you’re recording in the field, you may need to consider higher quality, more expensive interface preamps.
- What kind of microphones do you want to use? Dynamic mics can run on almost any mixer, but condenser mics require phantom power, which not all interfaces have.
- How many headphone inputs do you need? If you only want to monitor yourself, a single headphone input directly is likely enough. However, if you want everyone on your show to hear themselves, you may need to consider a larger interface.
- What podcasting software do you already own? Some interfaces come with a full suite of products, while others require you to purchase software separately.
With just two or three interfaces left on your list, you can easily narrow down to the best possible option.

Best Standalone Audio Interface for Podcasting
Choosing the best standalone audio interface depends entirely on your needs.
For example:
- Podcasters looking for simple live stream capabilities may find the Focusrite Vocaster works well on a budget.
- Existing ZOOM customers (or podcasters with a love for specific sound) may love the ZOOM U-44’s interchangeable podcast microphones.
- Brand-new podcasters looking for simple editing software and music libraries may appreciate the PreSonus Revelator io24.
Best Multi-function Audio Interface for Podcasting
The multi-function audio interface that’s best for you depends mostly on your situation.
You may find that:
- The TASCAM Mixcast 4 works well for recording lots of media on relatively large SD cards.
- The ZOOM PodTrak P8 can help with mixing, editing, and interfacing, as well as customizing your audio with a sound pad library.
- RØDECaster Pro 2 works well for connecting four people in person, as well as three ‘virtual’ guests through Zoom or Skype.
- The Maonocaster E2 is a cost-effective solution that allows you to experiment without a high up-front cost.
The Bottom Line on Podcast Audio Interfaces
The best podcast audio interface on this list is the one that suits your needs.
Maybe a standalone interface makes more sense for your use case, or a multi-function tool would offer utility over the long haul. Maybe the low-cost Maonocaster is a better fit for your budget, or you find that Focusrite equipment offers a better bang for your buck.
Either way, the goal is to pick the best match for you, your show, and your guests.
And once you’ve found the perfect fit, you can start exploring your other podcasting needs:
