What Audio Interface Do Pros Use? (10 Brands To Consider)

In days past, there was a stark difference between an amateur and professional recording gear, with pro studios having vast resources and rows of racks and processors. The landscape has changed with the advent of modern audio interfaces, and the lines between pro studio, home studio, and amateur recording gear have blurred.

Pros will use various types of audio interfaces, and not all of them cost hundreds or thousands of dollars. Steinberg, PreSonus, Focusrite,  Prism, AVID, Apogee, Antelope Audio, Universal Audio, RME, and Audient are the top pro audio interface brands of 2022.

Because there are hundreds of audio interface products available, we will explore the best AI brands and look at some audio interface products that offer exceptional quality and versatility for pros, whether in a pro studio or at home.

Let’s get started.

What Features Do Pros Look For In Audio Interfaces?

With home recording, most amateur sound engineers are too fussy about the interface specs, and as long as they can record guitars, mics, and other inputs to a DAW for editing, that’s pretty much all they need.

For a home studio, an audio interface that lets you record guitars, mics, and other inputs to a DAW for editing is all you need.

With professional studios, several features would be requisite from an audio interface to ensure that the resolution is pro-quality. Pro studios will often be required to work on complex projects like soundtracks for movies and videos or performance and broadcast quality recordings.

To this end, there are some very specific features that an audio interface would have to have for it to be suitable for pro use – so let’s look at those in more detail.

Sample Rates For Pro Audio Interfaces

The first feature would be the sample rate. Most amateur audio interfaces would be operating at 44.1kHz or 44100 cycles or samples per second.

If you think about this like a camera, a 1megapixel camera has 1 million pixels in the shot, while a 10megapixel camera has ten million pixels.

The sample rate for a pro audio interface will be 192 kHz or better.

This means that when you zoom in close on the image, the higher megapixel camera will give you far greater resolution and clarity on the details of the image, while the 1MP camera would blur or distort the image when you get in close up.

Sound is pretty much the same idea. The better the sample rate, the better the audio resolution, so most pros will look for audio interfaces that can utilize sample rates at 192kHz or better. While MP3 audio can be done at 44.1kHz, DVD audio needs to be at least 48kHz or higher.

A higher sample rate means better audio resolution – just like more pixels means better image quality.

Now, it should be noted that most digitally distributed music is at 44.1kHz, and the recording at higher resolution does take up more file space.

Professional engineers must have as much resolution as possible so they can downscale their audio to lower sample rates if needed. Still, it is a good idea to keep the original recording at the higher resolution as master copies.

The Bit Rate

The bit rate is how much audio detail you can get into an audio file and how much noise is eliminated during the recording. While it is always better to record at the highest sample and bit rate possible, in pro audio, there is a consideration on what hardware the audio will be played back on.

Playing back music on low-quality hardware (such as cheap market earbuds or budget stereo systems) will have no benefit if the audio is at a higher bit rate.

A high bit rate won’t help the audio quality if you don’t invest in good speakers.

However, using top-quality hardware (sound system or headphones) will deliver greater depth and detail for the listener.

The hardware to listen to the music or audio files will be very high-end for audiophiles and pro audio. With 24-bit recording, the dynamic range would be around 144dB, producing a near-perfect recording with almost no noise.

audio interface speaker
Look for an audio interface with higher bit rates and sample rates to capture a higher-quality recording.

The higher bit-and-sample rates are essential to truly appreciate the essence and quality of the performance, whether vocal or instrumental. For example, CD plays back at 1,411 Kilobits per second (KBPS) while mp3 audio ranges between 96 and 320Kbps.

That’s between 4X and 14X greater resolution than this common audio format. For a pro audio interface, you should be looking at a minimum of 16Bit, but 24-bit would be better suited to the demands of high-res audio.

Microphone Preamps

For vocal tracks, whether singing or voice-overs, the quality of the microphone preamps is another vital consideration as most studios will use top-end cardioid microphones when recording vocals.

The quality of the microphone preamps in your audio interface will determine how the recording comes out.

Because pro audio needs the cleanest, most transparent recording possible, high-quality microphone preamps are essential as they will lift the incoming signal to line level for recording.

Most pro audio interfaces also include a phantom power supply, another non-negotiable for audio interfaces for pro audio.

Inputs, Outputs, And Computer Connectivity

Some smaller home studios may only need four or even two inputs for a line (guitar/keyboard/bass) and an XLR for the microphone. Still, pro audio requires more as they will often be recording multiple instruments and vocals.

You might want an audio interface with enough connections (potentially half a dozen or more).(potentially half a dozen or more) for multiple instruments and vocals.

Suppose you are recording drums, for example. In that case, you could need five to eight inputs for the drums alone, and often, there will be a separate audio interface for the drums alone, while other instruments and vocals may be done through another AI.

Knowing how many inputs you need for your studio is critical so you can buy the AI with the required number and type of inputs the first time.

Most pro sound cards would have outputs for monitors, engineer and performer headphone outputs, and even talkback features so the engineer can communicate with the performers or artists.

If you are investing in a pro audio interface, you would need these features included, plus you will also want a USB 2 or USB connection if you aren’t using FireWire.

You will probably also want a USB or USB 2 connection if you don’t use FireWire.

Remember that your AI converts the analog sound into digital, so you want the best possible connection between the AI and the studio computers so that your audio editing software gets the highest possible quality files.

Why Low Latency For Pro Audio Is Critical

As audio evolved from analog to digital, the issue of latency became a major consideration. Latency effectively delays the analog and digital audio signals returning to you.

Consider it like an echo almost and the difficulty you would have if there was a half-a-second delay in hitting the note on your guitar and hearing it.

Latency makes a big difference in how long it takes to hear a note after playing it.

Modern connections like USB 2, USB 3, Thunderbolt, and Firewire for MAC or using a PCIe interface offer exceptionally low latency, and any latency around 5-6milliseconds is optimal. However, latency up to 20 milliseconds would not be noticeable, but the lower the latency, the better.

Remember that latency is affected by other components like the computing power itself, the software being used, and the AI connections.

Now that we have looked at the audio interface features and specs required for pro audio let’s look at the top-rated audio interface brands for pro audio.
