The 7 Best Lowest Latency Audio Interfaces That You Can Get Today


Audio interfaces are a crucial element of your recording studio, as it’s where most of the audio processing happens. That’s why taking your time to research which audio interfaces are available and what would be most beneficial for you is so important.

Whether you’re starting with a Beginner Audio Interface or opting for a high-end recording station, options are endless, with devices that provide plenty of functions and features for every need in the music industry.

However, there’s one feature that every musician, producer, and audio engineer looks for in audio interfaces: low latency.

If you’re starting your home studio, I’m sure you’ve heard many users and manufacturers talk about the latency of their devices. But what is latency? Let’s take a look at why this is such an important thing to consider when buying your first low latency audio interface or upgrading your old one.

A low latency audio interface is the best way to upgrade your workflow and audio performance because it delivers the best audio quality and gives you the possibility to expand your sonic palette.

The best audio interfaces feature fantastic sound quality and near-zero latency giving you full control over your audio recording process.

Let’s delve into the world of USB audio interfaces with close-to-zero latency!

What is Latency in Audio?

We call latency the time gap between a stimulus and a response. For example, the times it takes our brain to process a sound and when we hear it and then react to it. In music production, this is the time it takes for the sound to travel from its source to our ears.

To understand how this process works and what we mean by “gap”, first we need to understand how audio interfaces work. Let’s take a singer as an example: to record a voice, they’ll need a microphone connected to their audio interface, which is connected to a computer running a DAW (digital audio workstation).

In this example, the singer is the source of the sound whose voice will be recorded with the microphone. When we hit record on our DAW in the computer, the microphone will capture the sound and transfer it into the audio interface.

A low latency audio interface has a built-in ADC (analog to digital converter) that does precisely that; it converts an analog signal to a digital signal so our computer can store the sonic data.

The converted signal is then processed by our DAW, where we will see the singer’s voice translated into a waveform. The input latency is the time gap between the singer’s voice and our DAW recording and showing the waveform on our computer.

Then, the DAW will send the audio recording back to the audio interface, where its digital to analog converter (DAC) will transform that digital signal into analog and send it to the output device, such as studio monitors, speakers, or headphones.

The output latency is the gap between our DAW playing the audio until we hear it on our speakers or headphones.

When we talk about latency, we refer to the delay caused by all the processing involved. The sum of the input latency, the processing between, and the output latency is called round-trip latency and is measured in milliseconds. Latency is a critical parameter to consider; it will be a determinant factor in low latency monitoring of our audio recordings.

Having an audio interface with high latency will make our monitoring a chaotic task, as we will be listening to our singer’s voice, guitar, or MIDI instruments with an unbearable delay. That’s the reason why we should always look for the best low latency audio interface. Luckily, almost all current audio interfaces in the market provide low latency, even for home studios.

What Can Affect Latency?

Now you might be wondering what causes latency and how to avoid it. We know our signal travels through many layers that cause a delay between processes, but it’s not the only thing affecting the latency.

  • Our Computer CPU’s Speed

    The first thing you’ll need besides a low latency audio interface is a computer; the lower your CPU, the more latency you’ll get. With a higher CPU speed, you will have more power to process more effects and plug-ins on your DAW.

  • Buffer Size in DAW

    Buffer is the memory used in your computers for audio storage while your computer processes the audio coming from your audio interface. From your DAW, you can change the buffer size; the larger the buffer, the more time your computer needs to process audio.

    More size will allow you to use more plug-ins and have better performance and stability in some systems. However, having more time for processing the audio means slower response and more latency.

    There is no perfect buffer size; there will be times when you need the lowest latency possible, but on other occasions, you’ll need to choose performance over latency. Finding a balance between stability and low latency will be up to you and your requirements.

  • The Sound Quality of a Low Latency Audio Interface

    The quality of the audio interface may affect latency. A cheaper audio interface will have fewer components to provide audio quality, including low latency.

  • Connectivity

    The connection type is another thing that can affect latency. The most common connections are USB-A, USB-C, Firewire, and Thunderbolt. We can find USB 2.0 and 3.0 as well as Thunderbolt 2 and 3. The fastest connection and those that will have less latency are USB 3.0 and Thunderbolt 3.

    The audio signal is transported through the cables of our interface, and having the fastest connection will give us lower latency. However, to achieve this, it’s fundamental that each component of your recording setup is compatible with the others, ensuring a smooth, high-speed data transfer.

  • Compatibility

    Working with computers means working with an operating system, software, and drivers. We need to make sure our DAW is compatible with our computer, that we have our audio interfaces’ drivers up to date, and that everything is compatible with each other. Not having compatible hardware and software can have a significant impact on latency.

How to Reduce Latency?

Whichever low latency audio interface you choose, you might still find some latency when recording or performing live. After all, it’s virtually impossible to achieve zero latency, and that’s okay.

However, here are some things you can do to reduce latency:

  • Reduce buffer size.
  • Do not use plug-ins while recording (you can add them later in post-production.)
  • Keep your low latency audio interface drivers and DAW updated.
  • Use an audio interface with direct monitoring.

Now it’s time to jump to the best low-latency audio interfaces. We’ll provide you with all the necessary information to make the best decision for your projects, needs, and current hardware.

Let’s dive in!

What to Look For in an Audio Interface Before Buying?

When you’re ready to buy a new or your first audio interface, there are a few things to consider, so here is a brief list of the top things you need to look out for searching for the best low latency audio interface.

  • Inputs and Outputs You Need

    Before jumping into low latency audio interfaces like the Apogee Element 88 or the Quantum 2626, first, ask yourself if you need all those inputs and outputs. Yes, those ones provide incredible performance and lower latency than others, but remember, latency does not depend only on your audio interface.

    Buy equipment based on what you need: define how many instruments and microphones you will use and if you’ll be recording mostly songwriters or full bands. Then ask yourself how you will monitor your mixes; how many headphones, monitors, or speakers you have.

    Doing this exercise will help you narrow down your search and the price range of possible low latency audio interfaces.

  • Direct Monitoring

    Direct monitoring is indispensable for any producer, and thankfully manufacturers include this feature with almost all low latency audio interfaces. But just make sure you check this on the specs or see a DM button on the interface. This feature will bypass the lengthy processing of analog-to-digital and digital-to-analog conversion that low latency audio interfaces do. Instead of sending the signal to your DAW, it will go through an independent routing to your headphone output.

  • Connections

    I suggest you look for a connection using USB 3.0 or Thunderbolt 3. You can run projects with higher tracks, outstanding performance, and low latency with these connections. Also, check if the audio interface is powered by a USB-C cable or DC-powered.

    Most of the time, you can connect your audio interface to your computer via a USB cable, but that’s not always the case. Thunderbolt interfaces are also a common option these days, and they deliver fantastic audio quality.

    If you buy a second-hand audio interface, you might come across one with a FireWire connection, which used to be one of the most common connections among Mac users for high-speed data transfer. If your computer doesn’t have a FireWire port, you can’t use this type of audio interface, as FireWire to USB-C adapters won’t solve the issue.

    In general, a USB-C connection is the safest option.

  • Compatibility

    Check that your computer is compatible with the audio interface you want. I know this seems obvious, but sometimes we get so excited about hardware that we forget to look into the requirements. On every audio interface’s official website, you can find a compatibility list.

    Software processing is also something you should focus on. Plug-ins often require plenty of CPU, which has an impact on your low latency audio interface. Make sure you buy an audio interface that runs smoothly when you apply your favorite plug-ins and will still give you the chance to direct monitoring your recordings.

  • Bundled Software

    Unless you want to upgrade your audio gear, you’ll probably need a DAW and plug-ins to start working with music production. Most low latency audio interfaces offer some software, usually lite versions or trials, but not all of them. Check out the software included, as sometimes the final price is a great deal for what’s inside the bundle.

    Often, when you buy audio interfaces, you also get everything you need to start recording your music, so don’t underestimate the importance of bundles when choosing your new audio interface.

    Look for audio interfaces that offer a standalone DAW plus a series of plug-ins that will satisfy your recording needs. If you choose wisely, you might be able to save a lot of money and time by buying everything you need in one go.

Final Thoughts

The best audio interface is the one that best satisfies your needs without overcomplicating your workflow. So don’t just look for multiple outputs, a phantom power switch, or optical outputs if you don’t think you’ll need them in the foreseeable future.

Look for a device that can record pristine sounds and enhance the dynamic range of your content. Make sure you get an interface you can use to connect your MIDI interfaces to your DAW. Pay attention to compatibility: there’s no use in buying the best audio interface if you can’t connect it to your computer hardware via a USB cable.

If you’re recording other artists, two-line outputs would definitely come in handy. Finally, get an interface that comes with an impressive software bundle: you’ll save a lot of money and expand your sonic palette considerably.

All in all, the best audio interface combines great performance, latency-free monitoring, and good audio quality for recording sessions that will deliver professional results at a fraction of the cost of a professional recording studio.

After analyzing many of the best audio interfaces, we considered these seven to be the best low-latency audio interfaces, according to their features and user reviews. So, which audio interface has the lowest latency? Our answer is Quantum 2626. But it might not be the best low latency audio interface for you, so we have decided to give you three options.

For the lowest latency, we would go for the Quantum 2626, which has less than 1ms latency. It has the lowest audio latency, and that’s why it’s our first spot.

The second spot is tied with the MOTU UltraLite-MK5 and the Clarett+ 2Pre. Both are similar in price, are Mac and Windows compatible, and the size and features are good enough for both beginners and professionals.

On our third spot, we choose the Apollo Solo Thunderbolt interface due to its portability. It’s great to have a low-latency, DSP processing, and Unison preamps in such a small device.

But don’t let us decide for you. Discover all that’s available in the audio production market and start your creative journey!
