What Is An Audio Interface And Why Is It Important?

Video: “What Is An Audio Interface And What Do We Do With It?”

Audio interfaces are hardware pieces that expand a computer’s sonic capabilities. They add various outputs and inputs to your sound production setup and give you more space to work.

They allow you to attach other instruments and microphones to your computer. This way, they give you more versatility, more control, and will enable you to be innovative with their music.

You can replay, edit, and make new music of your own. Most people use them for podcasts, recording music, video production, sound designing, and voice-overs.

Audio interfaces are essential if you are working on a professional level. There is always a difference between the equipment of a beginner and a professional.

Similarly, your audio interface transforms your musical production from basic to professional.

Connecting audio interfaces to your setup is also relatively easy. The most common route of connection nowadays is USB ports. Some versions of audio interfaces also come with esoteric connections, such as PCMCIA slots.

Keep this particular point in mind when you choose an audio interface for yourself. Select a product that can efficiently connect with your computer. Doing this will help avoid any future problems related to connectivity.

Plus, it will also narrow down your options in the market so you can choose easily.

Now that you know all about the importance of an audio interface, what it is, and what it does, let’s move to the primary question of today’s discussion, “does an audio interface improve sound quality?”

The short answer is yes, it does.

While expanding inputs and outputs, an audio interface significantly improves the computer’s sound’s overall quality.

This hardware reproduces accurate representations of music and sounds, which helps when you record, replay, and mix audios.

An audio interface makes a difference because microphones produce very low voltage levels on their own. The interface’s preamplifier boosts the microphone to an extent where it becomes usable for recording purposes.

The sound that goes through an audio interface is fuller and has a broader range.

Even though it’s not as apparent when you compare bare signals, the difference is more visible when you run a signal to a cab sim and an amplifier. It is especially obvious when you distort or overdrive the same signal through an amp sim.

Remember, all these benefits vary among different audio interfaces. The cheap ones are lower in terms of quality and might not give you the same professional experience as a high-end interface.

In contrast, a good quality interface gives you clearer and faster transient responses and a bigger dynamic range.

Thus, it would be wrong to think that all audio interfaces are equal and will provide you with the same results.

Can An Audio Interface Negatively Affect Sound Quality?

Sadly, yes, a cheap or broken audio interface can negatively impact your computer’s sound quality. A lousy audio interface can potentially cause lower dynamic ranges and significant noise distortion.

Thus, to avoid these problems, you must:

  • Ensure that the audio interface you choose is high-quality and reliable
  • Spend a generous time doing your research on the product
  • Buy a new interface instead of a hand-me-down, especially if you don’t personally know the seller
  • Run the interface before or immediately after buying it to ensure everything is okay and you don’t need a return or repair.
  • Check to see if your audio interface is not broken
  • Take special care of this hardware while moving the computer so that you don’t break it
  • Upgrade it when need be and avoid using an broken, or faulty audio interface
  • Check this hardware immediately if you feel distortion in the sound

What Makes A Good Audio Interface? – A Brief Buyer’s Guide

While speaking of a good audio interface, there are certain things you can keep in mind to avoid making a regrettable purchase.

If you don’t have previous experience in buying one of these, the following buying guide will help you choose the most suitable equipment:


I/O Configuration

Noting the input and output configuration of an audio interface is the primary necessity when you’re buying one of these hardware pieces. This configuration will decide how many and what kind of inputs and outputs you have access to.

Different types of configurations can allow desktop units with two channels or systems that record dozens and hundreds of different channels.

The configuration of your audio interface is essential for your short-term and your long-term goals. When choosing this hardware, think of the inputs and outputs you are currently using and the ones you would like to use in the future.



As mentioned earlier, you must keep connectivity options in mind when you are buying audio interfaces. Some of the standard connection routes are Thunderbolt, Firewire, PCIe, and USB.

Most PCs have USB ports, while most Mac computers incorporate Firewire. Thus, when you choose an interface, make sure you know what your computer will allow a connection with.

If you buy something that doesn’t have connectivity with your PC, it’ll be a pickle finding a solution to that problem.


Tech Specs

Technical details like sample rates and bit depths might sound alien to you, but they are essential. Both bit depth and sample rates significantly impact your computer’s sound.

If you’re planning to work like a professional, the 24-bit range is the ideal recommendation. Similarly, sample rates’ impact is more subjective, and professionals like to use 48kHz, 96kHz, and 192kHz.



Similar to the issue of connectivity, if your audio interface is not compatible with your computer, the equipment won’t work the way you expect it to.

Make sure that the product you choose is compatible with your Mac or PC.



Satin brands are popular, well-loved, and reputable for their products, specifically audio interfaces in this case. Some of these brands include PreSonus, Focusrite, Behringer, and Audient.

Indeed, many other companies and manufacturers produce high-quality and reliable products. However, buying from famous, reputable brands is a safer option. They’ve been in the market for a long time, and they’ve made their name through customer service and optimal delivery.

Hence, you know their products well, you can ask other people who’ve tried them, and they’re significantly more reliable.

Ask your friends, fellows, and colleagues about their favorite manufacturers for audio interfaces. Then, do your research and find a brand that fits your budget, aesthetics, and other tech needs.



Indeed, the price tag doesn’t always represent the quality and efficacy of a product. However, it does give you an idea. It works incredibly well in the case of hardware equipment like audio interfaces.

While cheaper and inexpensive models are tempting, remember that they almost always have a catch. When it comes to tech and professional equipment, be generous with your budget and deliberately cut down costs.

Remember, this investment is for the long-term, and you will end up making the most of it. Thus, every penny you spend can be worth it.

So, Should You Invest In An Audio Interface? How Much Would It Cost?

Audio interfaces of good quality can last you about 5-10 years if you take good care of it. This hardware equipment is not as fragile as you’d think. The moving parts are relatively less, so there are minimal damage chances unless there’s a massive trauma.

That being said, do you need to upgrade an existing model?

Not necessarily. Unless you need any specific facilities and features that your current interface doesn’t have, there is no need to replace it and invest in another.

You can think about replacement in one of the following scenarios:

  • If the interface is older than 8-10 years
  • If the hardware is broken or damaged
  • If you know, the distortion in sound is coming from the interface
  • If there’s a better model in the market that has better features and you need it

Other Factors That Improve Sound Quality

Now that you’ve got the answer to “does an audio interface improve sound quality?” let us talk about a few other things that affect your computer’s sound quality.


A mixer can significantly impact the sound and as well as voice quality since it can control frequencies.


Speakers are the final output of the sound. A bad speaker can ruin the sound quality regardless of how the input and the other elements in your setup.

Thus, replace a lousy speaker with a good one. You’ll notice an immediate change.


Amplifiers can help increase the volume of the sound and improve its quality as well. However, remember that it does not change the type of sound your speakers pour out.

Regardless of how much you spend on an amplifier, the sound will still come out low-quality if your speakers aren’t delivering correctly.
