Things to Consider When Buying an Audio Interface


One common question most people ask when it comes to a computer-based recording is—why do I need an audio interface? After all, my computer has a built-in sound card that can also play the same role. Why can’t I use it then?

Well, if you have ever thought the same, then you’re “demn” right about it. But, your computer sound card is quite limited when it comes to recording and mixing. Most of these sound cards only offer a consumer-grade stereo line output that only allows you to connect your audio players.

When it comes to professional recording works, a computer sound card is totally inappropriate as it offers limited connectivity that limits its usefulness. Remember, the professional recording will require you to have an XLR input for the mic, a high-Z phone plug for the guitar, and quality outputs that will help you monitor your recordings via the speakers and headphones.

So, with that in mind, an audio interface is truly a centerpiece to your home studio as every sound that goes into the computer and out via the speakers/headphones must first pass through the audio interface.

Since an audio interface is such an important part of your home studio setup, it’s highly paramount that you choose the right audio console that will take care of your home studio. Here are some key pointers that will help you make an informed decision.

  • 1. Your Specific Recording Needs:

The first thing you need to think of when buying an audio interface is your specific recording needs. Remember, there are so many models of audio consoles already in the market. Most of these audio devices are identical but what makes them different is the amount of audio work they’re designed to handle.

Therefore, if you’re looking to do stereo mobile recording, making quick song demos, composing songs using virtual instruments, or recording guitar/vocal overdubs, choosing an interface that’s designed to handle your specific recording or producing tasks is very critical.

  • 2. Connectivity Format:

With the advancement in technology, recording using computers such as PC, Mac, and IOS devices have been in the font run in most home studios. Due to this reason, most audio interface manufacturers have kept pace with this modern trend by engineering audio consoles that work seamlessly with these computers and the various apps and software these computers and IOS devices run.

Now, some of these connection protocols you’re likely to come across include;

USB: Most of the new generation computers use the latest USB 2.0 and 3.0. Their excellent transfer rate and high bandwidth make them the best for audio applications. To reduce the bulk, most audio consoles are now designed to draw their power from the computer through the USB line.

FireWire: This is another connection protocol that’s primarily found in most Mac computers such as Laptops and desktops.  Unlike the USB 2.0 and 1.0, this one offers an excellent high-speed data transfer that makes it the best for multi-channel recording tasks.

For PC users looking to enjoy the high-speed services of the FireWire, you need to install an expansion card to your computer for you to use it.

Thunderbolt: This type of connection protocol is the latest and the fastest type of connection that’s currently second to none. Currently available in the newest Mac computes, this high-bandwidth Intel technology offers the fastest data transfer rates making it the best for performing demanding computer-based recording tasks.

Although this feature is currently available for Mac devices only, all is not lost for PC users as they can use Windows computers equipped with Thunderbolt option cards.

PCI Express: Also known as PCIe, this type of connection protocol is primarily found in desktop computers in the form of an internal card-based connection that’s plugged directly into your computer motherboard.

With such a connection in your desktop computer, your PC will be able to provide high-speed bandwidth that will allow your audio interface to handle multiple simultaneous inputs and outputs. One thing you need to understand though is that your desktop must have a PCIe slot for you to install it.

  • 3. Desktop or Rackmounted Audio Interface:

When choosing an audio interface, most people usually forget to ask themselves whether to get a desktop or a rack-mounted model. Before you make your decision here, you first need to think of your specific home studio type—is it a starter type of studio or is it a professional studio?

If you’re just starting out or maybe you don’t have lots of gear already in your rack, choosing a desktop audio interface is the best option as they’re pretty compact and budget-friendly. However, the only downside to these audio interfaces is that they take much of your desktop space due to the multiple wiring and clutter.

On the other hand, if you’re using a professional home studio with tons of gear that need multiple connections, then a rack-mounted audio interface is the best to consider as they’re more advanced and help to reduce clutter from your desktop.

  • 4. The number of Simultaneous Inputs/Outputs:

This is one of the most important factors that need to be examined with extreme caution when shopping for an audio interface. The number of audio channels, as well as the signals its ability to handle at the same time, should be examined with extreme care.

For instance, if you’re a starter recording at a basic level, a simple two-channel desktop audio interface with a pair of mono signals or a single stereo signal is the best to consider. If you’re a songwriter looking to capture your voice and acoustic guitar simultaneously via the speakers or headphones when singing, a 4 input interface will be the best.

If you’re doing professional recording using multiple gears such as drum kits, samplers, and multi-effect units, using larger interface systems that can handle 16 or more inputs/outs will be the perfect option. Additionally, shopping for audio consoles that include S/PDIF and ADAT connectors is an added advantage as they allow you to connect external devices that require digital connections to operate.

Finally, the best audio interface under $500 should be compatible with your specific computer. Although there are some audio interfaces that only pair with specific Mac and PC computers, always check the compatibility to ensure that what you buy works with your specific computer.

  • 5. Software Compatibility:

This is another major factor that can make a huge difference when shopping for an audio interface. With so many options available in the market, high-profile manufacturers are setting themselves apart from the rest of the pack by designing audio consoles bundled with software and onboard DSP compatibilities.

  • 6. Sound Quality:

Really, sound quality is number six on our list? Yes. One huge reason why sound quality was not at the top was due to one reason—even the least expensive audio interfaces can now afford to deliver great quality sounds without struggling.

Although the former is true, there are several key factors/features that can directly influence the audio quality of your specific audio console.

Bit Depth: To cut the long story short, the higher the number of bits, the better the level of fidelity an audio interface has. Fidelity is simply the measure of how well a digital bitstream can capture your music’s dynamics while eliminating external noise.

For instance, a 24-bit recording that delivers 144dB of dynamic range can eliminate more external noise for smoother sound quality as compared to one with a 16-bit recording delivering a dynamic range of 96dB.

Converter Quality: This is another spec that influences the audio quality of your audio interface. A/D and D/A converters are specifically used to convert incoming analog audio signals into digital data and vice versa. Therefore, the higher the quality of your audio interface, the better the quality of the analog/digital and digital/analog converters.

Sampling Rate: Another factor that affects the quality of your output sound is the sampling rate. Without getting too technical, the higher the sampling rate of your audio interface, the higher the level of fidelity hence the better the sound delivered.

What does this mean? In case you’re working on a demo or maybe you’re working in a beginner home studio, a 16-bit/44.1KHz sampling rate is the best to consider. On the other hand, if you’re dealing with pro-level projects and commercial soundtrack works, then a higher 24-bit/96KHz or 192KHz sampling rate will be required.

  • 7. Price:

this is the very last factor you need to think of after you’ve examined all the above factors. Although some people prefer to start with the price first, starting off with the rest of the factors then narrowing down all your options to an audio interface that fits your bill will be the best approach.


What Is an Audio Interface?


In almost all industries, advancement in technology has led to one huge thing—efficiency. In the world of recording, DJing, sampling, and music production, the same has been the case as every home studio has one specific goal—to record high-resolution sound.

But, how can you achieve this yet most modern computers are only fitted with soundcards that can’t support the high-resolution output required for professional production and DJing? Well, in such a situation, a piece of equipment known as an audio interface is required to translate the analog signals from your mics to digital ones for easy recording.

Now, your home studio may have all the equipment required for professional recording and production. You may also have a powerful computer equipped with computer-based digital audio workstation software (DAW).

But, without an audio interface, the recording will be impossible as your computer doesn’t have the XLR Male/Female, MIDI I/O, Instrument Level DI, TRS and RCA inputs and outs that are required for connecting the various instruments.

So, an audio interface is simply used to bridge the gap between digital and analog signals. When recording, this audio console simply converts the analog sound waves from your microphone into digital binary codes that your computer can easily understand and process.


FAQs: Frequently Asked Questions

Q-1: Is a Sound card Similar to an Audio Interface?

Basically yes. A sound card and an audio interface are the same things. Their main purpose is to convert analog sound from your microphone to a digital signal that your laptop, desktop, iPhone or iPad can easily process and edit.

However though, despite performing the same task, these two audio consoles have two major differences. One is that a sound card fits inside the computer while an audio interface is used externally.

Secondly, a sound card is used for light recording tasks especially if you’re doing it alone while an audio interface is best suited for professional recording works as it has more inputs and outputs that allow you to connect more recording, podcasting, and production equipment.


Q-2: Do I Need an Audio Interface After all?

This common question has been a source of confusion for so many people. To cut the long story short, it all depends on the type of equipment you’re using. For instance, if you’re using a USB microphone, then you won’t need to add an interface.

According to most people, an audio interface is generally a box with multiple inputs and outputs for connecting various equipment such as electric guitar, drum sets, mics, speakers and headphones among others.

Although an interface provides a way to connect multiple pieces of equipment simultaneously, there are other devices that are audio interfaces themselves and don’t require an interface to operate. One such example is a USB microphone.

If you happen to shop for the best mic that has an XLR-USB cable, then you don’t need an interface as you can easily connect the cable to your computer. For the case of a headphone, you can use headphones out to connect them to your computer then get ready to record.


Q-3: How do I Pair my New Audio Interface to a Computer?

Before we even begin, you need to understand that an audio interface is a USB soundcard. So, as long as you have a USB connection (in terms of the USB port and USB adapter), pairing the interface with your computer is easy and quite straightforward.

For quite a long time, USB 2.0 and 3.0 have been at the center of focus among most recording and production home studios. However, with the advancement in technology, newer, faster, and better connection options have emerged such as Thunderbolt and firewire.

One drawback though with these two USB connections is that they’re quite pricey. Secondly, some ports such as Thunderbolt are only available in Mac computers so you have to buy one otherwise PCs won’t work unless you have a special Thunderbolt option card.


Q-4: When do I need an audio interface?

Here, there are some questions you’ll need to ask yourself. First, are you planning to do a professional music recording? How many microphones are you planning to use? Do you need more power than what a USB port can provide? Does your microphone use XLR output?

The answer you’ll have to all these questions is what will define whether you truly need an audio interface in your home studio or not.

If you’re doing a professional recording, an audio interface will most probably be required as it can convert analog signals from your mics to digital signals that your computer can understand for editing purposes.


Q-5: Does an audio interface reduce CPU usage?

It can, but it’s not necessary. Now, this question comes amid a huge misconception that audio interfaces can take the load from your computer to give your CPU some time to breathe. On one side, an audio interface can offload CPU usage though slightly in a way that you can’t notice.

On the other hand, this may not be the case if you’re using a computer that cannot handle your DAW projects. Overall, don’t shop for an audio interface expecting it to reduce CPU usage as its main purpose is to handle and route inputs and outputs while converting analog signals into digital ones and vice versa.


Q-6: Does an audio interface improve sound quality?
