When audio interfaces that made use of hard disks were first introduced into the market, they were costly, big, and accessed by professional studios alone. The cost of owning an audio interface then was similar to owning an average car, and it also required the use of hardware cards sometimes.

Since computers started becoming more powerful and reliable in handling certain tasks, making use of additional expensive hardware became unnecessary. This made way for portable USB interfaces, which created a solution for home recording and project studios.

These USB interfaces come with designs that permit hooking up with microphones and any other instrument like hardware synths, basses, and guitars.

Factors To Consider When Shopping For A Reliable Audio Interface

It would help if you considered key considerations before making a payment for an audio interface, but whatever you settle for depends on your recording requirements. These factors are;

  • Number of outputs
  • Number of inputs
  • Phantom power
  • Portability
  • Latency
  • Preamps
  • Converter
  • Bit depth and sample rate

Number Of Outputs

The number of outputs an audio interface should have will depend on what instruments you will be hooking up with this interface and where you desire to use the audio interface. An audio interface with multiple outputs will be perfect for mixing console with several channels. Still, if you use a laptop without additional equipment, you do not need an audio interface with several outputs. Hooking up a simple stereo output with headphones and studio monitor speakers delivers great performance when recording.

Number Of Inputs

The number of inputs an audio interface possesses decides how many instruments you can hook up with it. For use in pro-studios, an audio interface with multiple inputs will accommodate other devices like guitar amps and vocals, a bass amp, and a drum kit.

In other cases, pro and home recording studios do not necessarily need too many physical inputs. Not having too many physical inputs makes it easy for a solo artist to access an instrument or microphone at a time. It will be great if you have in mind the scenarios you will want to use an audio interface before making up your mind.


Purchasing huge racks or bulky instruments isn’t in vogue anymore. In the case of a small USB interface, you can connect an audio interface to a computer using its USB cable. The portability of an interface makes it compatible with a laptop in any working environment. This means you can work in a studio, at home, or even set up in a park.


Latency issues have been a real problem for so many audio interface manufacturers. Audio interfaces today comes with speedy connections and onboard processors, which reduces latency issues to a point where it isn’t noticeable anymore. When considering which audio interface to go for, an audio interface with a superb latency performance is a good investment.

Phantom Power

You will need a condenser microphone to engage in an acoustic recording or a serious vocal performance. You can count on a condenser microphone to clearly pick up details, but only when the audio interface has a 48-Volt phantom power supply. An audio interface with a 48-Volt phantom power guarantees capturing intricate performances when you use a condenser microphone.


If you record analog signals from an electric guitar or microphone, a preamp helps enhance levels to a noise ratio and decent signal point. It would help if you had an audio face with a powerful preamp that will offer you loud noise greater than unwanted noise in simpler words. Depending on circuit design, some preamps have designs that make them sound better than others, so the preamps in your audio interface must be worth it.


Converters are another important feature you need to take a look at when shopping for an audio interface because they are responsible for handling analog signals’ translation to digital signals. A converter handles this conversion before storing the converted files on a computer’s hard drive, and it re-converts the digital files into analog when they are played back. A rule of thumb common to everyone is, if your audio interface has an expensive converter, it will produce an impressive audio quality, meaning you get what you pay for.

Final Thoughts

The truth is, most audio interfaces can be used for mixing, mastering, and recording, but you shouldn’t neglect these factors when shopping for an audio interface. There are so many audio interfaces on the market, making purchasing one confusing for you. Still, you do not have to worry anymore as this review has broken down every piece of information you need to know.

The result you get from what you have mixed and mastered depends on these factors that we have discussed in this review, and the best audio interfaces we have discussed in this review will offer you the best sounds you desire.
