Our Comprehensive Buying Guide
If setting up a home studio is next on your sonic adventure lists, then an audio interface becomes a mandatory piece of technology. The many specs such units come with and the variety of affordable audio interfaces available for sale might slow the shopping process, though.
To help you narrow down the extensive list of options and choose the best USB audio interface for your needs, we have compiled a short buying guide below. Give it a read to find out more about the key factors to consider before hitting the order button.
Being picky about the audio interface you use is actually a good thing if professional results are desired. As the name suggests, this type of product is about audio performance, and that’s the first thing you should consider. You’ll see that almost every audio interface on the market comes with a few specs listed, and one of them regards the bit depth and sample rate.
These deserve great attention as they have a direct impact on the sonic results delivered. A bit is equal to 16 dB, which means that 16-bit audio will have a dynamic range of 96 dB. The thing is that when working at 16-bit, the quiet sections of an audio piece might be actually noisy.
That’s why production professionals use 24-bit audio interfaces, which have come to be considered the standard in this field. The sample rate of an audio interface holds great importance as well. While a 44.1kHz model is a popular choice as it can capture and reproduce all the sounds humans can hear, many professionals go for upper sample rates.
Now, it all depends on your particular needs. If you want to post MP3 audio online or release a demo on a CD, working at 16-bit/44.1kHz might just do. However, if you want to release instrumental music, such as jazz, in a high-resolution format, then working at 24-bit/96kHz is the starting point.
Also, get as much information as possible about the digital converters featured as they hold great significance as far as the audio performance ensured is concerned.
Inputs and outputs
When buying such a product, be it a cheap audio interface or a pricier one, what you want to record is of equal importance. This takes us to the I/O configuration of the model you’ve set your eyes on.
A singer-songwriter might do with a pair of inputs. If that’s your case and you want to sing and play your guitar at the same time, then make sure you go for a model that has two mic preamps as you will need one for your guitar mic and one for your vocal mic. Think of how many mics you want to record at the same time and consider the number of inputs offered by a specific model.
The number of outputs depends, again, on your particular interests and the type of outboard gear you’d like to use for your projects. Having MIDI and digital I/O proves to be of great help if you intend to expand in the future. MIDI inputs will allow you to connect various MIDI devices, while the digital inputs and outputs will help you expand the unit’s I/O channels.
Portability and other features
If you’re on the road a lot, getting a USB audio interface is the thing to do. Many affordable audio interface models run on USB bus power, and such a design will provide you with enhanced flexibility.
Many of the latest products in this line come with such features. Whether you want to buy a Focusrite audio interface or a Behringer audio interface, make sure you don’t overlook the computer connectivity options before you buy.
Reading an audio interface review of the model you’d like to buy before actually placing the order is always an inspired thing to do, even if it’s a cheap audio interface. Also, check out the software or recording tools included, if any. Such bundles will help you get started right away and often prove to be more affordable than if the tools are purchased separately.
Frequently Asked Questions:
Q: What is an audio interface?
A simple audio interface definition describes this piece of equipment as the hardware that connects audio gear, such as microphones, to a computer. Such interfaces are designed to convert analog signals into digital ones so that the computer can process them. They basically get sounds in and out of computers.
To do so, the audio interface uses certain types of connections, including FireWire, USB, PCI/PCIe card, and Thunderbolt. Audio interface USB models are highly popular these days, given the portability and flexibility they ensure.
As we’ve said before, the audio interface does the same thing with the signal conversion in reverse as well; therefore, an audio interface receives digital information from a computer and converts it into analog signals that you can hear using headphones or studio monitors.
Most such products, including cheap audio interfaces, feature line-level analog I/O, mic preamps, and even digital I/O. Audio interfaces are thus a must when it comes to recording vocals and instruments and doing so in high-quality audio.
Q: What does an audio interface do?
What an audio interface does is to provide you with the hardware needed to connect your instruments and microphones to your computer so that they can exchange information and, thus, ensure the required audio information conversion. This piece of hardware will be the front end of the recording system you use.
For example, if you want to record yourself singing, the analog signal that gets into the mic input of the audio interface you use goes through the built-in mic preamp to reach a line level. After that, the signal is sent to an analog-to-digital converter that changes it into digital audio information that goes to your computer through different connection types.
The same happens in reverse and, thus, the digital information is sent from your computer back to the audio interface over the USB cable and goes through a digital-to-analog converter that will change it into an analog electrical signal. This signal can then feed various headphone outputs, studio speakers, and line-level devices.
Q: Do I need an audio interface?
If you want to record vocals or instruments and do so in high-quality audio, then an audio interface is a piece of audio equipment you might want to invest in. Using a dedicated audio interface comes with various advantages.
Many computers feature good sound cards that can help you cater to basic recording needs, but the sound quality and I/O offered by these cards are limited and, more often than not, consumer-grade.
An audio interface will provide you with the possibility to connect various analog and digital signals, and such products come with converters and components that will make sure the audio quality ensured is superior. That’s why they are used to record and monitor production-quality audio.
Using a Scarlett audio interface or one from Behringer will get you a different and superior level of audio than the stock sound card that is built into a computer.
