The Best 5 Audio Interfaces for 2017

best music making software


There are many prerequisites to creating music. If your aim is to have complete domain over your art, you will require an audio interface. Seemingly trivial, an audio interface is a simple device that allows you to maintain full control over how your computer's input and output stream of audio. In this article, we will be reviewing what makes a great audio interface, the best audio interfaces on the market, and what audio interface may be right for you. The following audio interfaces are great choices in today's market.

What Is An Audio Interface?

To understand what to purchase, it is an important preliminary step to discuss the functions and capabilities of an audio interface. The audio interface is a piece of hardware that is responsible for converting any analog signal to digital signal that comes through an input jack, and any digital signal to analog signal through the output jacks. In essence, this piece of hardware can be as simple as a playback monitor or as complex as the large boards within professional audio studios. Based on this, an audio interface is generally used as a supplement to the audio capabilities of the average computer. For the purpose of this article, we will discuss viable options for the home studio because most professional studio interfaces will cost upwards of $300,000.

When To Use An Audio Interface?

Many viable options will diminish the need for an audio interface. For example, it is possible to purchase a USB microphone and a pair of speakers that are compatible with your computer and record your favorite composition. Unfortunately, this method will dramatically decrease the quality of your recording due to the lack of optimization provided by a USB connector. Alternatively, integrating an audio interface into your arsenal will give you the ability to improve the quality of your speaker monitors, utilize better microphones, change the signal routing of your recordings, and integrate outboard gear into your recording process.

Using an audio interface as your primary method of audio signal routing will improve the quality of your recording because the audio interface is created as an AD/DA (analog to digital/digital to analog) machine, whereas your computer is meant to accomplish a variety of tasks. Most audio interfaces will reproduce higher fidelity audio during playback in comparison to an average computer. An audio interface is critical to any serious recording environment; the interface will give you the ability to record more than one microphone at a time -- essential for recording instruments like drums, guitar, and brass. Lastly, you cannot use a condenser microphone (due to the lack of phantom power) unless you have a +48V compatible audio interface. Although it is beyond the scope of this article, the inclusion of a condenser microphone is crucial to most recordings.

How To Connect To An Audio Interface?

The connectivity of your audio interface depends on the product you ultimately decide to purchase. The majority audio interface will connect via five connections, USB, firewire, PCMIA or PCI slots, and an ExpressCard slot. The most common connection will be USB. However, your level of power will usually dictate the type of connection in which the interface requires. This is the most important preliminary step for choosing an audio interface.

Which One Should You Choose?

The choice of connection type depends on the level of power you require. If you are in charge of an operating professional studio, it is likely that you will need a high-speed connection to a PCI connector. If you will are operating an independent studio, but you plan to record live sessions, a FireWire port will serve you (if you aren't recording a full orchestra or content of that nature). Lastly, if you are building a personal studio for general applications without the need to record more than four microphones at a time, a USB 2.0-3.0 audio interface will fulfill all that you require.

Another important factor to consider before your purchase will be the number of inputs/outputs you need. This ranges based on your objectives. As a general indicator, think about the instruments you will record. Each instrument has an "optimum" amount of microphones that will reproduce the best sonic characteristics during playback. The general rule of thumbs are as follows:

5-piece drum kit (3-14 (sometimes more)) microphones

Acoustic guitar (1-2) microphones

Electric guitar (2-6) microphones

Horn instruments (1-3) microphones

Bass (2-6) microphones

Vocals (1-4) microphones

Grand piano (2-8) microphones

Outside of personal recording, it is beneficial to acquire an interface that has at least four inputs/outputs, so you have that ability to get a decent record a performance on most instruments.

Additional Requirements

The primary reason why most musicians buy an audio interface is to improve the quality of their recordings, compositional accessibility, and enhanced playback quality. However, an audio interface can integrate different signal processing capabilities like compressors, equalizers, and preamps to further increase your domain over the recording. Furthermore, you should ensure the audio interface of your choice supports three-pin XLR inputs as these inputs can decrease your noise floor exponentially (given the correct XLR cables). As stated previously, an integral part of many recording environments is the inclusion of a condenser microphone. These microphones are necessary because of their ability to garner the best of both ribbon microphones and dynamic microphones in their transducer capabilities. Based on this, it is vital that you choose an audio interface with +48V or phantom power capabilities.

The last thing to consider is the ability to process MIDI and line level input. MIDI is a widely used application of music that is accessed through a MIDI port. Without a MIDI port, you must use a USB port (if your MIDI instrument supports this option). A MIDI port will decrease latency in recording, enhancing your experience. A line level input serves a similar purpose to mic level (XLR). Alternatively, a line level input (generally 1/4" TRS or TS jacks) will provide a more balanced and grounded connection. This means you will not gather as much noise when recording over long distances. Based on this, this function is more suitable for a professional/independent studio environment where recording and monitoring will be done in separate rooms.


The Steinberg UR22



The Steinberg UR22 is the quintessential tool for the musician who is experimenting with their recordings. The price of $150 is perfect for anyone who does not necessarily know whether they want to invest the time in learning how to record.
