Some of the most important considerations to keep in mind when buying an audio interface are the number of inputs, number of outputs, and phantom power.

Portable Audio Interfaces – Common Questions

Should you get Mixer or Audio Interface?

When you think of a recording studio you usually think of a huge mixer and an engineer masterfully moving the sliders on it. But in reality, you don’t necessarily need a large hardware mixer.

Software development has made sound mixing digital. Sure some people still like doing it the old way with analog mixer, but as a minimum, all you need is a simple audio interface to connect and transform your analog signal into digital for your computer to read. After that, you’ll just have to mix everything in your DAW (digital audio workstation software, such as Logic, Pro Tools, Ableton Live, etc).

Also, you should know that some of the mixers on the market today do act as audio interfaces as well, so if you’re looking for it, you can get a 2-in-1 option as well.

What does an audio interface do?

An audio interface is, to put it simply, converting your sound from analog into digital, so that your computer can read it. It’s necessary if you want to record your sound through your computer with any decent sound quality.

How many inputs/outputs do I need?

The number of inputs really depends on how many things you want to record at once. If you’re a singer/songwriter, you’ll probably need just two (one for your mic and one for the instrument). If you want to record more, you’re going to need more inputs (as for more instruments or mics at once).

As for the outputs, you should look out to have at least one stereo output, as well as a headphone/monitor out, to ease up your recording sessions.

Does the interface affect sound quality?

Since the audio single will be going through your interface, it has the potential to affect the signal. Ideally, your audio interface will record a clean signal.

If you invest in a decent quality interface, then the sound quality should be good.

If you buy a low-quality audio interface, then you may get noise and distortion introduced into the signal.

Do I need phantom power?

If you have equipment that does need phantom power, then your audio interface will need phantom power.

The most common item that people have that needs phantom power are condenser microphones.

Check your equipment before buying an audio interface to make sure it suits your needs.

Can I use a USB mic instead?

Sound quality recorded through a mic and audio interface is almost always a lot better than using USB mics.

However, USB mics are better than nothing and they may suit your needs.


We hope this article has shed some light on the best portable audio interfaces that you can find online. Be sure to pick something that suits your budget, while also making sure to check the specs, particularly with a focus on inputs, outputs, and phantom power availability.
