What is a USB audio interface?
An audio interface is basically a piece of hardware that is used to improve and expand the sonic capabilities of a computer. You can call it an external expansion sound card that provides input and output audio signals to and from a computer under the influence of DAW software.
How does it qualify for professional use?
Most of the audio interfaces carry +48V phantom power, a single XLR input/preamp, stereo TRS outs, and a headphone input that is 1/4″. This is the very least specification, in most cases, as the price increases, the input and output interfaces increase, and so does the connectivity range. Of course, the more expensive ones are more feature-rich.
USB vs. USB-C connectivity:
The confusion between USB type-C and MicroUSB 2.0 connectivity in audio interfaces has been baffling music makers, especially the newbies, for a long time now. In general, USB type-C connectors are faster and support higher bandwidth than the typical MicroUSB 2.0 connector.
The Type-C connectors can stream data in both directions, while the MicroUSB 2.0 has to wait until information from one side is streamed. This way, the overall process and efficiency with Type-C connectors become faster and more functional. Besides higher bandwidth and speed, the USB Type-C connector also carries more power.
The most important features to look for in a USB audio interface:
We have already discussed this in the ‘USB vs. USB-C connectivity’, but apart from the two-basic type of connectors, we also have Firewire, thunderbolt, and PCI-E connectors. The main differences between these connectors are as follows:
Input and output channel count:
The input and output channel count varies according to the professionality level of the audio interface. Typical, the most basic ones have input and output count of one to two ports while the professional audio interfaces might come with more than 20 ports.
The number of ports you need in your studio depends on the number of tracks you need to record, analyze, or monitor at a time. For solo musicians, the port count can be as little as two to four songwriters who work on a small scale are safe with four to eight ports, however, when band members are recording a song or audio at least a 16-port audio interface is needed.
Input channel types:
There is a difference between input count and mic preamp count, which is why newbies and beginners usually fail to realize the fact that the total count of input channels on an audio interface is typically a reference to different audio types. Mostly, the three types of input channel types on an audio interface are:
This is just a nerdy term that refers to the size and shape of the audio interface. We have two types of interfaces, usually: desktop and rock-mounted interfaces. As the name suggests, the desktop interfaces are smaller and more compact compared with the rock mount ones.
The desktop interface usually sits on your table, and the rack-mounted interface is a standard-size rack unit. For home studios and beginner’s desktop interfaces are ideal since they don’t require any special mounting, are easy to use, and the best part is, they are reasonable.
In most cases, audio interfaces are compatible with almost all DAW software. However, we can have a few exceptions. Suppose you are not loyal to a specific DAW software. In that case, you don’t have to worry about this section, but if you have one specific software that you cannot make music without you might have to consider the compatibility of an audio interface with it.
Ninety percent of the top DAW software is compatible with all kinds of audio interfaces. In case you want to check the compatibility, you will have to search thoroughly through the company’s website. In most cases, this information is not embedded in the user manual or the notebook that comes with the hardware. You might find software compatibility information on the FAQs page.
Getting the best-sounding and most flexible audio interface for your studio has never been more challenging. Your power and sonic requirements might meet by a significant number of units, but the large number of choices you have makes things difficult.
There is nothing as confusing as buying an audio interface due to the dozens of choices you have in the market. Each one is designed for a certain type of compatibility with different connectivity. In this article, we have reviewed the seven best USB audio interfaces for a home recording studio, so that this daunting task becomes easier for you.
An audio interface is a crucial hardware for mixing audio or even producing music in your professional or home studio. In most cases, beginners don’t understand the complexity of technicalities and overlook them. This article was all about helping you find the best audio interface on a budget.
