Things To Look For When You’re Buying A Sound Card

After you’ve decided to get yourself a sound card, you have to look through the numerous options available in the market. However, picking a dedicated sound card doesn’t have to be a hassle. Here are some factors you need to keep in mind while buying one.


The foremost important factor while choosing a card is whether it’s compatible with your system. You don’t just want to buy a card with great features but isn’t compatible with your PC. Even if it has an affordable price tag, ask the dealer whether it will support your audio devices.

Surround Sound

All modern games, movies, and music support surround sound. So, if you have a fantastic sound system at home and want to enjoy the best sound quality, choose a card that supports 7.1-channel surround sound support.

On the other hand, if you’re going to use only PC speakers or simple headphones for the audio output, such a card with virtual surround sound is not necessary. In that case, you can just go for a normal one and save some cash.

Gaming And Audiophile Cards

Separate cards are designed for gamers and audiophiles. If you want an outstanding gaming experience along with good listening options, you need a gaming sound card. The music performance is great with these cards too.

For those who have a quality speaker setup and want a high-quality audio experience, go for an audiophile sound card. These work like a charm with high-end headphones and speakers to give you an immersive experience.

USB And PCIe Cards

You have to check out the type of your card while buying. If it’s a USB card, then it will easily plug into your PC via a USB port. Some of these cards have microphones attached to their bodies allowing you to directly record sounds with them.

PCIe sound cards are installed inside your PC and use the motherboard’s PCIe port or PCIe interface to provide you excellent sound quality. As these cards use power from the PCI port and offer lower latency than the USB cards, their sound is a lot better.

Signal To Noise Ratio (SNR)

This ratio defines the quality or clarity of the sound your card is producing. It’s the difference between the noise and signal power, so the higher this ratio is, the clearer will be your sound.

For example, if an SNR is 50 dB, it means that the audio signal is 50 decibels more than the noise signal. This is a poor SNR value, as you will be able to hear the noise clearly only when the volume is turned up high.

That’s why you must always go for a sound card with a minimum of 100 dB SNR.

MP3 Encoding

A card having an mp3 encoding facility can handle mp3 files without much support from the CPU. This will be great not only for music but for gaming too. With the gaming mp3 soundtracks being handled by the sound card, your CPU can focus more on the game, making it run more smoothly.
