Guide to the Best Sound Cards

Best Sound Cards

A sound card may seem like an unimportant item in a PC setup, but there are cases where this component gains importance. These cases can be in a gaming tower, in a computer for audio editing or simply a PC for enthusiasts.

That’s why you should follow a series of tips in this guide to help you find the best sound card for your PC that offers you the best experience, be it for games or to watch movies or for more advanced tasks.

Tips when choosing a sound card

Surround Sound

Many sound cards offer to surround sound support. In the case of gaming, this means that you can hear everything that happens in your environment, such as hearing the footsteps of an enemy or listening to their weapon reloading in a first-person game. For movies, you’ll have a cinematic surround sound experience. Find a sound card that offers surround sound support if you like the experience of watching movies or to have an advantage over your enemies in games.

Response frequency

Frequency response is the idea of ​​delivering clear, crisp audio to the listener. The frequency response value comes in a range form. The ideal frequency response that is the audible range for the human ear is 20Hz – 20 KHz. When looking to buy a new sound card, make sure the sound card provides a frequency range that is greater than these values.

Total harmonic distortion (THD)

The total harmonic distortion of a sound card represents the amount of distortion that occurs. Some sound cards have a type of shield to protect it from audio distortions from other devices located on the computer. An example of a sound card that uses this type of protection is the ASUS Xonar Essence STX that uses the EMI shield.

Signal / noise ratio

The SNR measures how much the desired signal exists at the audio output over the power of the unwanted noise in the audio. The higher the SNR value, measured in decibels (dB), the better the quality of the audio produced with less background noise. When looking for a sound card, be sure to buy one with an SNR value of more than 105 dB minimum.

Ambient Audio Extensions (EAX)

This is something that is less used but is usually included in many models. You are especially interested if you are a gamer since many games use these EAX audio extensions to provide you with real surround sound effects, making you feel completely immersed in the game.
