Audio interfaces are a staple in pretty much every professional recording studio. Simply put, they’re devices that convert the analog input of sound to a digital version that your computer and software can recognize.
Good audio interfaces are expensive primarily because of the quality of sound produced. There’s no better way to record multiple instruments at once. The other factors that influence the pricing of audio interfaces are their reliability, build, features, and the fact that they have a small market.
In this article, I’ll detail the factors that influence the pricing of audio interfaces. Then, I’ll examine if audio interfaces are worth the steep prices. So here’s a breakdown of the factors that affect the pricing of audio interfaces and the reasons why they’re so expensive.
Reasons Why Audio Interfaces Are So Expensive
The primary function of audio interfaces is to convert analog sound to something that can be processed digitally. To that extent, the audio interface works by using advanced technology and physics to reproduce the sound in the recording as accurately as possible.
Here’s a breakdown of the factors that affect the prices of audio interfaces:
Sound Quality
In modern audio interfaces, the sound is recorded and reproduced with a great degree of precision. They also have built-in components like the microphone preamplifier, called mic preamp, or simply, preamp of very high quality.
This allows for the audio signal to be amplified to the ‘line’ level needed for recording.
Most audio interfaces have preamps that record with high gain, low noise, and a high level of transparency. This results in a sound that is very clean and pure.
So much so that some artists and producers prefer recording with external preamps
so that their recordings have lower transparency and more character.
While you could record with a soundcard and get by, especially with how advanced technology is nowadays, there is no denying the difference in sound quality.
The sound quality varies between audio interfaces, with the higher-end ones producing more accurate recordings of the audio input.
There are different classes of amplifiers used in audio interfaces regarding sound quality, and they’re usually labeled A, B, AB, or C. Among these, class A is the highest, and the rest follow in sequence, with B being lower than A and so on.
Interfaces that use a class A amplifier will produce higher quality sound and tend to be more expensive.
Functionality and Features
A short explanation of this factor is that audio interfaces offer you a specific functionality and access to features that no other device does.
The first among these are the I/O or the Ins and Outs. Of course, just about every device that allows you to record will have at least one channel for recording. For instance, if you’re recording yourself on your phone, your voice will be recorded with a single, mono input.
Most other devices and the simpler audio interfaces will let you plug in one stereo input. But this is hardly enough if you’re recording with more than one mic.
Being able to plug in multiple XLR cables as you record is vital to professional and semi-professional recording units.
Another important feature offered by audio interfaces is zero-latency or low-latency. Latency refers to the lag between receiving the audio signal and converting it into digital. A zero or low latency feature allows you to hear yourself as you’re recording, without interruptions, letting you make decisions about the audio in real-time.
Samples rates are yet another functionality that needs to be considered, but this depends on your preferences. Sample rates refer to the range of frequencies you’re able to record. While you won’t always need a high sample rate, if you do intend to, then higher-end audio interfaces offer the option.
Build Quality and Component Parts
Like any other device, the build quality and the components play a huge role in determining the price. When it comes to audio interfaces, the components themselves are pretty expensive.
A good audio interface will have balanced inputs and outputs, high-quality amplifiers, a multi-parameter interface, and a whole host of other features. The hardware on all of these needs to be pretty solid to deliver the sound quality and recording flexibility that an audio interface promises.
Poor build quality will mean a poor audio signal recording and a less than accurate sound conversion. The less transparent the sound, the less flexibility you have when you get down to mixing it.
Component quality is also crucial for the digital to analog converters, which is the primary feature of an audio interface. If the signal received isn’t converted appropriately, you’ll end up with latency issues and low gains, and high noise issues in your recording.
Additionally, the build quality of the hardware is pretty essential when it comes to the knobs, dials, and I/O because these do see frequent use, and durability is vital when it comes to equipment like an audio interface.
All these requirements contribute to the steep price tags on most good-quality audio interfaces.
Reliability and Longevity
Audio interfaces are designed, tested, re-tested, and repeatedly reworked to produce consistent results.
When it comes to your recordings, you need to be absolutely sure that your equipment will stay consistent because you may or may not be able to control the other recording circumstances.
In a studio, you can definitely control the ambiance, the room tone, and noise to a great extent, but your instruments may or may not cooperate. Similarly, your voice quality will differ from day to day based on how you’re feeling.
In this case, your equipment must deliver consistent results. The makers of audio interfaces go through a great deal of trouble to ensure that you’ll have access to the cleanest possible recording of the input.
This testing is also why some brands are considered better than others in the audio industry.
The other advantage to audio interfaces is that the higher-end ones tend to be more compatible with the latest in digital recording software and computer systems.
The more expensive your audio interface is, the more likely it is that it will last you longer by retaining compatibility with your software even as the software receives updates.
Specialized Devices for a Small Market
The fact is that the recording industry isn’t exactly a large industry. It is small, and the audio interface is a highly specialized piece of equipment. This means that the prices can’t be pulled down by a large market.
The costs for development and manufacture for highly specialized products are high in general. When that product also requires expensive, high-end components, good build quality, and consistent results while being compatible with other devices, the costs go up further.
And finally, having to produce these in small quantities requires a high price so that the costs of research, development, and testing can be recouped.
Are Audio Interfaces Worth It?
Considering all the factors that make audio interfaces expensive, it’s hard to say that the device itself should be cheaper. So the real question that you’ll have to answer is if audio interfaces are worth the high prices.
Audio interfaces are worth it. The extremely high sound quality and low latency allow recordists to have a clean, true-to-life piece of audio to work with. This guarantees greater flexibility when working and a high-quality final product.
Audio interfaces are an indispensable device in professional recording studios for a reason. Professional quality sound needs professional quality gear, and that is why getting a good quality audio interface will make all the difference when you’re recording.
Final Thoughts
Audio interfaces are expensive because they are reliable, durable recording equipment that ensures high sound quality. While you could record without them, they are necessary for professional sound recording setups and worth the investment.
