If you want to connect your speaker cables and microphones to computers and other technical stuff to record through USBs, an audio interface is what you need.
This technology allows you to listen to whatever you’ve recorded through headphones, speakers, and studio monitors.
How Do You Set Up An Audio Interface?
Even though it might look and sound intimidating, setting up an audio interface is not that much of a hassle!
- Start by connecting your desktop computer or laptop to your interface. You can use any recommended connection for a USB for this purpose.
- Next, you are supposed to install all the basic, recommended drivers. Now, this part is usually an automatic step with a new system. However, sometimes, you have to install or download them yourself.
- Connect your audio interface’s outputs to the powered speakers.
- Next, launch or install your playback software or the selected audio recording.
- Select the audio software’s output and specify it for routing to the audio interface you just installed.
- If you have pre-recorded audio samples in your software, you can play them and test them.
- Connect your cables, microphones, and any other inputs to your new interface.
- Finalize the setup by testing an input signal. You can do this by routing a specific input channel to a particular software input and recording a tiny clip, as long as a few seconds or minutes.
- Now, play this short clip back and listen to the quality of sound coming from your speakers. If everything sounds good, it means that it is! Congratulations, you’ve successfully set up an audio interface!
What Is a DAC?
Video: “What is a DAC? – Explained”
A Digital to Analogue Converter, commonly referred to as DAC is a system that transforms digital signals into analog signals.
Simply put, a DAC converts all the signals that come from your music equipment and turn them into sounds that you can hear through the headphones.
You can commonly find Digital to analog converter chips inside the sound sources, and their prices vary according to their quality, manufacturing company, and many other factors.
How Does A DAC Work?
All kinds of audio signals are compression waves when you replay them, be it an MP3 signal or a vinyl.
When your computer records a particular analog signal, you will see it as a waveform.
A waveform literally looks like a wave, and it has two axes: axis X represents time, and axis Y represents amplitude or the power of the wave.
This wave, like any other, has two components: valleys and crests. One crest and one valley create a single period.
The number of periods in every second determines the frequency or Hertz. This frequency corresponds to notes and pitches; for example, higher frequencies correspond to higher notes, and lower frequencies create lower notes.
A Digital to analog converter receives a recording that was stored digitally, and then it transforms it into analog signals.
It does so by translating data bits from different individual digital files to analog electrical signals.
A DAC completes this process at the rate of thousands per second.
Then, the unit produces intersecting waves at all points and, since DACs aren’t always accurate, this intersection might lead to potential problems.
Such problems include:
- A narrowed dynamic range (the difference between potential sound volumes in a particular file)
- Aliasing (strange oscillating sounds mostly found in high-frequency notes)
- A limited bitrate (the amount of data expressed in a single second), and,
- Jittering, which is imperfections in the sound’s pitches
The Major Differences Between Audio Interfaces and Digital To Analog Converters (DACs)
While moving towards the debate of audio interface vs. DAC, let’s get to the point and start discussing their differences.
Now that you’ve learned and fully understand what each of these two technologies is, it’ll be much easier to comprehend why they’re two different phenomenons and why there’s a comparison being made.
- While starting from the fundamental differences, a DAC is a converter that transforms digital signals into analog ones so you can play them on your audio systems, like speakers, studio monitors, and headphones. In contrast, an audio interface also consists of a DAC, but it can also convert analog signals into digital ones so you can record them. This way, you can record your content through devices like microphones.
- While digital to audio converters are portable and charged by batteries, the same is not the case with audio interfaces.
- Since audio interfaces are more complex and professional, they are relatively more expensive. In contrast, if you are on a budget, you would want to go with a digital to audio converter since they are more pocket friendly.
- Audio interfaces are a convenient choice if you are looking for something high quality for your home studio. This technology allows you to record sounds directly through MIDI, TRS inputs, or XLR inputs to the DAW. Digital to audio converters are of good quality, and they do an excellent job at what they do, but they’re not as Hi-fi and professional as an audio interface.
Pros And Cons Of Audio Interface And Dac
Moving on with the discussion over the audio interface vs. DAC, let us discuss the pros and cons of each technology.
Understanding the advantages and drawbacks of both audio interfaces and digital to analog converters can help you realize whether a particular technology suits your needs and likings.
Go through each of these lists below and determine what pros you’re looking for and what cons you can compromise on; let’s begin!

- The most significant advantage of audio interfaces is their easier accessibility and larger physical size. Thanks to these factors, an audio interface holds the potential to build various input types in the unit.
- Audio interfaces can significantly improve and expand a computer’s sonic capabilities. This technology dramatically improves the overall sound quality that comes out of your computer. Thus, if you produce audio content through computers, these interfaces will help you out a lot.
- If you produce audio content on a professional level, an audio interface is what you need. Give you the quality, clarity, and pureness in the sound that you need. Plus, not all audio interfaces cost you a whole lot; if you look deep enough, you might be able to find an excellent affordable brand with high-quality products.
- Another essential advantage of an audio interface is its high usability. Since it is easier to use and manage, many people prefer using audio interfaces over other technologies like sound cards. It is also one of the primary reasons it is so prevalent in the first place. Audio interfaces provide high-quality recordings with ease of use- who doesn’t want that?
- Audio interfaces can be quite expensive. The reason behind their higher prices and costs include functionality, reliability, and quality. These are specialized devices, and they have a relatively smaller market, so they are not manufactured in bulks.
- If your audio interface is not expensive or high-quality, there are high chances that you might find faults in it. Thus, if you want to invest in an audio interface and produce high quality and professional content, being cheap isn’t going to help. In fact, you might as well not spend anything since, for the most part, there is no such thing as a good-quality yet budget-friendly audio interface.
