How to Choose the Best Audio Interface

Introduction to Audio Interfaces

All the popular models that we can recommend to everyone are discussed above. Each user can study the list and make a choice according to their needs. However, this does not mean that the offer on the market is limited to several devices. There are also a lot of the best audio interface solutions with different functionality, purpose, and in different price categories. To make a more voluminous choice, the user should be guided in the general concepts of this category of equipment. And then we will do a small review on this topic.

What is an Audio Interface?

As we already said, the audio interface (for home studio etc) or an external sound card is a means of reading data (sound) from external devices and transferring it to a computer for recording, subsequent processing, and so on. That is, the key task of this element of a personal computer is to convert a digital signal into an analog one, and then transfer it to headphones or speakers. Yes, almost all motherboards have an integrated sound card, but its power may not be enough to make a full sound recording. In addition, the integrated device will adversely affect the overall performance of the personal computer.

Therefore, the practice of buying an external sound card that will connect to a computer or laptop using a special high-speed audio interface connection, called FireWire, is common. Due to this solution, it is possible to significantly reduce interference, which positively affects the sound quality.

There are currently two similar standards:

  • IEEE 1394, which provides throughput at 400 Mbps;
  • IEEE 1394b, with a data transfer rate of about 800 Mbps.

There are also external sound cards that can be connected to a computer via a traditional USB connector. Such products usually provide access to speakers or headphones, as well as the ability to connect one or more microphones. Unfortunately, their maximum bandwidth does not exceed 480 Mbps. This may not be enough for professional sound recording.

The user can find and get advanced studio audio cards. Their main distinguishing feature is the presence of a large number of various outputs that can be used to connect a wide variety of musical instruments: electric, acoustic and bass guitars, microphones, synthesizers and so on. In addition, such audio intefaces are capable of high-quality sound from a drum kit. One of the distinguishing features of such products is the lack of the need to install drivers, however, you still have to install the software. It will be very useful when working with the equalizer and other settings.

Which audio interface should you get?

There are a few key issues to consider when choosing and buying an audio interface for  home, studio, live issues. First of all, there is no best audio interface in general. If the user has clear answers to these questions, search processes are greatly simplified. For example, it is important to know the number of inputs and outputs. 2 entrances and exits will be enough for podcasting and streaming, and 4-5 exits allow a person to record a small group at home. Also, the consumer should consider the type of connection, taking into account the data transfer speed and the type of computer. There are three main types, these are YUSB, Firewire, and Thunderbolt. And we must not forget about the sound quality and dimensions, along with the amount that a person is willing to spend on equipment. At the intersection of these factors, compromises are born. Several important factors will be considered in more detail below.


Analog vs. Digital
Analog vs. Digital

Due to the rapidly growing popularity of studio audio recording through computers and iOS devices, modern audio interfaces are designed to provide perfect compatibility with all types of platforms, operating systems and software. The most common connection types are listed below.

USB. It’s hard to find a computer without a USB 2.0 and 3.0 port today. Most USB-connected audio interfaces receive power directly from a PC or other host device, making it easy and simple to set up a recording session. iOS devices also mostly interact with audio interfaces via a USB port.

FireWire is mainly found on the MAC and in audio interface models designed to work with devices from Apple. This type of connection provides high speed data transfer and is perfect for multi-channel recording. PC owners can also use this port by installing a special expansion card.

Thunderbolt is Intel’s new high-speed connection technology. So far, only the latest models of MAC computers are equipped with the Thunderbolt port, however, it can be used on PCs with an additional Thunderbolt board. The new port provides high data transfer speed and has a low processing delay, due to which it meets the most stringent requirements in terms of computer sound recording quality.

USB is a generally accepted choice for most cases, but other types of ports provide higher speed and quality of data transfer, although they are somewhat limited in terms of accessibility to PC users.

Form Factor

The form factor largely determines the purpose of the device. If the user uses the audio interface at home or for studio, the issue of size and weight does not really matter. Although, if there is a need to save work space, you can choose from compact models. If an external sound card is used on tours or in any situation “on the go”, then it must meet several criteria. Firstly, it should be a solid case and a reliable assembly. The equipment must be resistant to external influences. Secondly, it is the same portability. The lighter and more compact the audio interface, the more convenient and easier it is to carry with you everywhere. There are also models that are designed only for installation in a rack, they are suitable for the studio and large concert tasks. Otherwise, you should always focus on models with free placement.


Your budget

The higher the price, the more functions are available, and the higher the quality of the materials used, the assembly of the device and, as a result, the sound. At first glance, you might think that it is better to take the model more expensive. But when it comes to unprofessional use, ultra-functional expensive top-quality models can be a redundant solution. The market offers many worthy solutions in a wide price range. The user can easily find an acceptable external sound card for podcasting and voice recording for $ 100 or less. If there is a need to create a small studio at home, the budget grows several times, but this is still an affordable and long-lasting solution at the price of 200-400 dollars. More expensive models are worth buying only if the user is clearly aware of the opportunities and advantages that similar equipment brings in each individual situation.


As you can see, the question of choosing an audio interface for a home studio is multifaceted and complicated at first glance. However, with a clear understanding of the market supply and basic functional criteria, the choice becomes as simple as possible. If you use the information above, choosing the best device for the situation is not difficult. Also, this information will help everyone start exploring the market on their own in order to find other, equally high-quality solutions. We wish you a successful and valuable purchase of audio interface!
