1. Introduction
When setting up your audio workflow, whether for podcasting, streaming, or building a home studio, you’re bound to face a critical question: Audio interface vs mixer – which one is better for you?
Â
While both tools play essential roles in audio production, their functions, strengths, and ideal applications are very different.
Â
In this guide, I’ll explain the unique features and uses of audio interfaces and mixers. By the end, you’ll know exactly which tool best suits your needs, whether you’re a podcaster, streamer, or musician.
2. What Is an Audio Interface?
An audio interface is a device that converts analog audio signals into digital signals for recording or streaming on your computer. You don’t have to much real time control, but you have high-resolution for further editing. It also does the reverse—converting digital signals into analog for playback through monitors or headphones.
Â
Simply put, an audio interface will allow you to connect your microphone to you computer. It will translate the analog signal into digital so that it can be processed in high-resolution. It is small, easy to use and can be easily transported.
Â
Modern audio interfaces, like the Focusrite Scarlett 2i2 or the MOTU M2, are designed to deliver high-quality sound while offering low-latency monitoring.
Core Features of Audio Interfaces:
Signal Conversion:Â Converts your microphone signal to digital and vice versa.
Inputs and Outputs:Â Includes inputs dynamic and condenser microphones and headphone outputs.
USB/Thunderbolt Connectivity:Â Connects directly to your computer for easy integration.
Phantom Power: Provides power for condenser microphones, without phantom power condenser mics don’t work.
Compact Design:Â Portable and ideal for small spaces.
- Resolution:Â Usually from 24-bit or 32-bit for dynamic range and sample rates from 44.1 kHz up to 192 kHz or higher.
Â
That is to say, high resolution ensures detailed and clean recordings, capturing subtle nuances in audio. This makes interfaces ideal for studio recording, music production, and you should evaluate your need for podcasting or streaming.
👉 Best For: Live sound. Podcasters with guests, live-streaming setups with multiple audio sources, and live musicians.
3. What Is a Mixer?
A mixer is a device that allows you to combine, process, and shape multiple audio signals in real time. Mixers are more commonly found in live settings but can also be used for recording or streaming, although, the resolution is lower if you need to edit.
Â
Unlike audio interfaces, mixers often include built-in real time controls, like EQ controls, effects like reverb, and multiple input/output options. Some newer mixers even have USB outputs for digital recording.
Â
In other words, mixers will also translate your microphone signal into digital format so it can be processed by your computer, but with less resolution. On the other hand, it will give you a lot of control over multiple audio sources and the ability to add effects. They are bigger and more complex to use.
Core Features of Mixers:
- Channel Control:Â Each input has its own controls for gain, EQ, and volume.
- Onboard Effects:Â Often includes reverb, compression, or delay.
- Routing Options:Â Flexible signal routing for complex setups.
- Real-Time Mixing:Â Ideal for live sound applications.
- Resolution: Digital mixers or USB-equipped mixers have resolution capabilities typically 16-bit to 24-bit. Sample Rate often capped at 44.1 kHz or 48 kHz, sufficient for live sound or streaming and real-time mixing rather than high-resolution recording.

5. Uses of Audio Interfaces for Streamers and Podcasters
If your primary goal is to record high-quality sound with minimal effort, an audio interface is the way to go.
Â
There are bundles designed specifically for this purpose, Focusrite has a great bundle containing a Scarlett Solo Studio 4th audio interface, studio condenser microphone with pop filter, XLR cable and high-precision headphones.
Why Streamers Should Use an Audio Interface
Some audio interfaces are designed with special features for streamers, like the Vocaster One, featuring Camera Output, Auto Gain and Enhance.
- Clear Audio:Â Audio interfaces provide high-resolution sound, some models with features like built-in compressors and preamps.
- Direct Monitoring:Â You can hear yourself without the delay caused by the computer processing the audio. This delay is called latency.
- Phantom Power:Â Necessary for condenser microphones. Not needed for dynamic microphones
Loopback: Let’s say you want your audience to hear what you hear when you’re streaming or remixing audio from an online video. That’s what loopback does. With this feature, you can send audio from your streaming platform of choice directly to their DAW and mix in external audio.

Why Podcasters Should Use an Audio Interface
Mixers have a steeper learning curve due to their advanced controls and routing options. However, they offer more flexibility for live and multi-source audio setups.
The same advantages above, with the addition that the high resolution provided by audio interfaces makes high-quality editing easier. You’ll definitely appreciate hearing yourself in real time with no delays with direct monitoring, and if you use a condenser microphone, well, you’ll need phantom power.
Â
- Simplicity: Connect your mic, adjust your gain, and you’re ready to record.
- High Audio Fidelity:Â Interfaces excel at capturing detailed sound for a polished podcast.
- Portability:Â Audio interfaces are lightweight, easy to setup and carry.
- Loopback: You can hear your guest’s voice and you own vocals along with background music or sound effects in real time.

6. Uses of Mixers for Streamers and Podcasters
A mixer might be the better option if you’re dealing with multiple audio sources in a live setting or need more control over your sound.
Why Streamers Should Use a Mixer
Until recently, mixers were gigantic and very complex. Some mixers are now designed for easier use and are more portable, like the Zoom PodTrak P8.
Â
- Real-Time Adjustments:Â Quickly adjust levels for game audio, mics, and alerts.
- Multi-Source Management:Â Usually, mixers have more inputs. It allow you to handle multiple inputs simultaneously.
- Built-In Effects:Â Add reverb, delay, or compression for a professional sound.
Why Podcasters Should Use a Mixer
- Guest Management:Â Mix multiple microphones and adjust each channel independently.
- Live Recording:Â Handle everything in real time for minimal post-production.
- Advanced Routing:Â Send audio to multiple destinations like monitors and recording devices.
