With the rise and miniaturization of digital technology, building a recording studio has become significantly easier. One of the key players behind this is the digital audio interface, a device that sits between a source of audio and your computer. Digital audio devices eliminate the need for a ton of home recording studio equipment, as everything from mixers to digitally-modeled guitar amplifiers can be had in small packages.

Digital audio interfaces take many forms. USB microphones, the Blue Microphones Yeti for instance, plug directly into your computer and obviate the need for extra connections and unusual cables.

Another common form of digital audio interface is a device that captures audio and sends it elsewhere, either directly to a computer for capture, or to external speakers for monitoring. While most computers include sound hardware, this often isn’t up to the task of making quality recordings. Additionally, the proximity of traditional sound cards to computer electronics often introduces a kind of buzz that is difficult to remove. Moving sound capture outside of the computer vastly minimizes this noise while often providing a much clearer signal.

One of the best USB audio interfaces for those wishing to quickly improve their sound is the Behringer UCA222 U-Control Ultra-Low Latency 2 In/2 Out. Sporting dual inputs and outputs, this interface can help you to connect more than one source of audio to separate outputs. Additionally, it comes with a large bundle of home recording software to get you started even faster.

For those needing more flexibility, the M-Audio Fast Track may be just what you need. This unit features a variety of inputs and outputs, including some for professional-grade studio gear, as well as RCA connections for stereo output. The mic input is even phantom powered, thus making available a broader selection of higher-quality mics.

Many digital audio interfaces communicate via USB, and this works well in most situations. Professionals or those requiring the highest quality might instead opt for firewire interfaces, however. These have several key advantages. First, they’re generally faster, though the difference in speed is only noticeable to the most extreme recording artists. It is also possible to chain several firewire devices together, a fact which may prove vital for anyone with lots of USB devices already.

The M-Audio Firewire Solo US35030 is one of the best firewire audio interfaces on the market. Not only does this unit sport an impressive amount of inputs and outputs, but both can accept digital audio, thus ensuring the highest-quality audio from supported devices. Its frame is also rack-mountable, making it an excellent addition to any professional home studio.

Digital audio interfaces are the easiest way to get a newer, crisper sound with the least expense. Whether you’re looking to transform your guitar into a cornucopia of eclectic instruments, or even if you just want clearer sound than your internal card can produce, looking into digital audio interfaces is a great way to diversify when building a recording studio.
