The Best PC Sound Cards of 2017
With video quality rapidly going up, game physics exploring never before seen detail and virtual reality devices getting more and more affordable, one part of the media we consume is often getting overlooked – sound. Most of us use the sound interfaces integrated into motherboards, which often times is not enough to fully indulge yourself in a movie, get the highest quality sound when listening to or producing music and when you need just that little bit of edge over your opponents in a video-game. This is why we have compiled a short list of what we believe to be the best PC sound cards out there as of right now, each covering different needs for different users.

Our picks for the best PC sound card
What to consider when choosing a sound card?
Basically, there are four key aspects to what you should be looking for when choosing the best sound card for your budget. If we are not going very very deep into PC sound cards then the four criteria mentioned below is everything you need to know to compare and choose a PC sound card.
Overall Audio Performance
This is definitely the most important thing to look for in any sound card – overall performance. To understand the overall performance of a sound card, typically three main performance measurements are used – frequency response, SNR (signal to noise ratio), and THD (total harmonic distortion), which are the main characteristics of audio quality. Of course, they are not super-accurate and will give you just an idea of the potential an audio device has.
Frequency response describes the range of sound frequencies a sound device can cover and SNR pretty much does what it says on the can – describes how much unnecessary background noise may be getting through your sound system. THD is used to describe how much surrounding electronics inside your PC can affect internal signals within your sound card, i.e. how well shielded it is from outside signals. Today most sound cards have THD close to zero and frequency response covering pretty much all sound frequencies you can throw at your system, so people pay the most attention to SNR since it conveniently turns overall sound quality into an easily comparable number.
Sample Rate and Resolution of Sound Data
What is sample rate? It is the speed at which the sound card can reduce a continuous signal to a discrete signal. The latest trend in sound cards is 192kHz, which one might consider complete overkill since humans can only hear sound with a frequency of 20 Hz to 20 kHz. But there is a catch! Higher sampling rates really help with analog to digital conversions (ADCs) and digital to analog conversion (DACs).
Why is resolution important? As we all know higher resolution means lower background noises. It’s because larger bit depths decrease the total harmonic distortion and also increase dynamic range which all results in a better signal to noise ratio. High-Resolution Audio is just a industries marketing term.
All sound cards on our list support up to 24bit / 192kHz audio format.
Sound Card Software Features
Most cards will have a whole array of attributes that help you enhance and simplify audio adjusting. These software adjustments are very important because they help you achieve the best audio performance from your sound card. It will also allow you to connect your sound card to A/V receivers and audio playing software on your computer.
Also important is compliance with APIs (Application Programming Interface), which allow the sound card to connect with other software better and gain additional features via this connection. Examples of this would be the classical EAX for gaming or SBX Studio Pro for Sound Blaster products – these APIs allow sound cards to produce the most precise 3D sound environment. This is more the icing on the cake, with specs like SNR still being most important, but when you look for perfection, every little thing helps.
Connectivity to PC and Other Sound Devices
First of all, you need to know how the card connects to your PC – it can use a PCI or PCIe port, while external cards will most likely use a USB port. Also, look at the processor which will power the sound card. Important to note is the S/PDIF standard, that, in Layman’s terms, increases audio quality by reducing the times the audio is compressed between the source material and your ears.
A sound card is worth nothing without a sound system to support, however, depending on how sophisticated an audio system is, it can use different connections. Here we will not go much into detail on how each connector works and will focus on letting you know the basic differences, so you can find the sound system that fits your sound card perfectly or vice versa. As seen below, optical TOSLINK and coaxial RCA cables support the S/PDIF standard.
- 3.5 mm / 1/8” – the most common type of connector, that most casual audio devices use since this connector can support different stereo and audio signals, although it is not capable of providing sound quality as high as optical or coaxial connections. Main visual differences – connector tip shape and “belts” on the connector.
- 6.35mm / 1/4” – also known as the phone connector, since its history started in the old call centers where operators connected calls using these cables. Today this connector is mostly used by sound professionals, although you can sometimes stumble upon it in some high-end consumer devices as well. While similar to the popular 3.5mm jack, this connector is much bigger and requires an adapter to connect to its more popular cousin.
- TOSLINK (optical) – supports the S/PDIF standard. TOSLINK are also known as optical cables since they transfer signals via laser light through the cable, which is why this signal is less susceptible to electromagnetic noise but causes most cables to be short (5m max). The main visual difference – square connector housing.
- RCA (coaxial) – supports the S/PDIF standard. In consumer-grade sound systems, two RCA cables are used to carry sound data to the right and left channels and are often used in surround-sound systems. Main visual differences – two connectors on one cable and a simple, straight plug.
Sound card descriptions
Why does a high-end sound card matter?
Years have passed and sound cards are coming back. Sound cards are not an essential part of building a PC, but new generation sound cards are designed to have more advanced features to appeal to audiophiles.
If you are not a hardcore PC user you can easily live without a sound card, but it could be a great purchase for gamers and enthusiasts. Sound cards will help you create a realistic 3D sound environment, they greatly increase sound output, with a much richer frequency range, and increase overall sound quality. If you are considering to buy a sound card you also should have a quite good sound system to feel it. Cards like ASUS Essence STX II and Creative Labs Sound Blaster Z will definitely improve overall sound quality. More than ten years ago when I built my first PC on my own, high-end sounds cards were very expensive, but now you can buy a high-end sound card for around $100-250.
Of course, we could buy relatively cheap sound cards, but is there any point to buying one? Well, there is but only if your hardware codec on motherboard dies. At the same time, the reason to buy the best sound card today is to boost overall sound quality. The new generation of sound cards can really impress audiophiles with awesome features like replaceable op-amps, high signal to noise ratios and high-end digital to analog converters (DACs).
A very brief history of sound cards
Sound cards started to fade away when Windows Vista was released. Microsoft decided to only support software audio, one of the biggest reasons was that over 40% of support calls for Windows XP were related to sound cards.
Largest sound card manufacturer Creative Labs continued to produce X-Fi cards, but concentrated on OEM deals, headsets and speakers. Only a few are using sound cards in their systems now, but most current motherboards integrated codecs are far from perfect. Almost everyone knows what I mean, we all have struggled with strange audio issues, mostly with Realtek’s Audio Codecs.
Now sound cards are slowly coming back and it all started with the Taiwan-based ASUSTeK (ASUS), a company known for its wide range of motherboards. ASUS created Xonar under their brand and began shipping a line of sound cards, and while some of their sound cards were low-budget, most of them are quite pricey. Currently Creative may be considered the leading company in sound card manufacturing and development, with a whole array of different options, not differing only in quality or iteration but countless different software and hardware features.
Summary of the best sound cards
From our list, the best sound card would be Halo Claro, with its super-high audio quality coupled with the lower price (when compared to ASUS Essence). The only real downside of this sound card would be having to purchase a PCI adapter and that’s it. Anyone looking for an exceptional sound for consumer-grade price should consider this card.
If you are looking for a cheap and reliable option, the Sound Blaster Audigy would be the best sound card for you as it provides all of the basic benefits of sound cards for an incredibly low price – even the 7.1 channel model will cost you less than a $100.
ASUS Essence STX II seems more like the link between sound devices for a regular consumer and an audiophile, hence the high sound quality and an accordingly high price, so if high-end gear is your thing, this might fit your needs better. For gamers, the Sound Blaster Z might be the best choice on the basis of different software support to improve in-game sound, a decent headphone amp, as well as the advanced microphone technology to raise the quality of any voice chat.
There is a huge amount of different sound cards out there, with an ever-increasing amount of software and trinkets to improve the audio experience even more. Creative Sound Blaster series alone has a ton of different models to go through (such as ZxR or X-Fi HD), but in our list, we focused on the most practical models for everyday consumers while trying to find the best cost/practicality options. We hope that our list helped you choose the best sound card for your needs.
