Specific Needs

Focusrite designed its Scarlett product line as six audio interfaces with unique features catering to different sound production needs.

For example, it would be best for absolute beginners to get either the Solo, Solo Studio, 2i2, or 2i2 Studio to acclimatize them to the basics of music production in the home.

Once they have mastered the fundamentals, people can pick the mid-range Scarlett 4i4 or 8i6.

At the pinnacle of the series are the Scarlett 18i8 and Scarlett 18i20, which are perfect for seasoned sound producers, artists, and musicians.

Number and Format of I/O Interfaces 

It will also help to determine how many input devices you intend to plug into the audio interface.

The most basic device accepts a microphone for vocals and another cable for musical instruments. 

If you have other devices, such as a bass guitar and drum kit, you might want to get a Scarlett with more I/O ports.

You might also need to consider the number of headphones the audio interface can accommodate for simultaneous tracking.

It also helps to know the type of connections your devices need, such as ¼”, RCA, XLR, digital, or 1/8”.

Check if you need MIDI, ADAT, AES, S/PDIF, and other optical digital I/Os. 


There is a Scarlett audio interface for every budget.

For example, the Scarlett Solo and 2i2 are suitable for people who may not have the budget now but can still leverage the devices’ impressive music production capabilities.

There are also the middle ground products – the Scarlett 4i4 and Scarlett 8i6 – satisfying the music production needs of advanced beginners.

Even the product’s high-end models – the Scarlett 18i8 and 18i20 – are still more affordable than other brands. 


Why is Scarlett the best-selling interface in 2023?

There are many reasons why Scarlett is the best-selling interface in 2023.

Let us start with the brand.

This UK professional audio company is a four-time recipient of the UK’s Queen’s Awards for Enterprise – two each for Technology and International Trade.

It is easy to see that Scarlett audio interfaces have enviable technology and a user-friendly design to match.

Focusrite designed its Scarlett audio interfaces to do only three things: provide users the best sound, the most pleasant experience, and the fastest speed.

Scarlett audio interfaces offer an enjoyable experience for anyone from the novice musician to the hardcore sound producer.

Their sound processing performance is perfect for those who want only the best sound to come out from their home or professional studio.

Is Focusrite Scarlett really the best interface?

Many people think the Focusrite Scarlett is the best audio interface today because of its pristine sound performance, reliability, effortless setup and operation, and affordability.

However, other people may beg to disagree, primarily because they prefer other brands or looking for product features the 3rd-generation Scarletts do not have.

Like any other product, deciding about the best audio interface boils down to personal preferences relative to one’s needs.

Any product that addresses a potential buyer’s pain points is worthy of the best audio interface accolade.

Nevertheless, it is worth pointing out that Focusrite will not receive the UK’s most prestigious royal award if not for its cutting-edge technology, user-friendliness, and exceptional audio processing performance.



Focusrite’s impressive line of Scarlett-series USB audio interfaces are perfect for modern sound producers, artists, musicians, and music-loving folks.

There is a Scarlett for every type of musician, from the Solo for absolute newbies to the 18i20 for people who are passionate enough to embark on a professional studio-quality sound production right in the home.
