Channels

The most advanced multi-channel audio format that a sound card is capable of outputting.

2. Standard stereo sound on two channels — left and right. This format allows you to provide a sense of surround sound (especially when using headphones), which is quite enough for most simple tasks. However, it noticeably loses to multi-channel sound in terms of the "immersion effect", which can be critical for demanding gamers and audiophiles.

5.1. The classic and most popular multi-channel surround sound format today: a centre channel, two front and two rear channels allow you to achieve a full-fledged “surround effect”, and a separate subwoofer channel provides rich bass sound.

7.1. The 7.1 format differs from 5.1 by the presence of two additional channels. There are several options for localizing these channels — for example, a pair of side speakers, a pair of additional speakers above the front ones, etc. Anyway, the 7.1 format provides a more reliable surround sound transmission than 5.1, but such cards are more expensive, and there is less specialized content for 7.1.

When choosing a sound card by the number of channels, it is worth considering such moments. Firstly, multi-channel options are capable of producing sound in simpler formats (for example, a 7.1 card can be used for 5.1 acoustics), and stereo sound output is support...ed by all models in general. Secondly, modern multimedia software (in particular, codecs) allows you to output multi-channel audio through a card with fewer channels — for example, play 5.1 sound through a two-channel card with stereo speakers without quality loss. Thirdly, for the full-fledged operation of multi-channel sound, you will need not only a card, but also appropriate acoustics; therefore, it makes no sense to specifically look for a multi-channel model if you plan to use exclusively stereo speakers.

Audiochip

Brand of the audio chip installed in the sound card.

The audio chip is one of the most important parts of a sound card, a kind of "heart" of the whole circuit, and it is on its characteristics that the sound quality and other capabilities of a particular model largely depend. Knowing the brand of the chip, you can easily find various information on it — official specifications, test results, reviews, etc. — and based on this, draw a conclusion to what extent this sound card is able to meet your requirements. Of course, for ordinary video cards (see "View") there is no need to delve into such details, but when choosing a gaming or audiophile model, they can be very useful.

Standards

Various standards and special digital audio technologies that the sound card is officially compatible with. For example, the Dolby and DTS standards in various variations are used primarily for multi-channel audio tracks in films, while DirectSound and EAX provide high-quality “surround” sound in games. In fact, the ability to work with one or another standard is largely determined by the software part of the system, and not by the characteristics of the sound card; however, official compatibility means at least the full compliance of the card with the requirements of the standard and the minimum risk of conflicts at the hardware level.

ASIO

Sound card compatible with ASIO standard.

ASIO (an abbreviation for Audio Stream Input/Output, i.e. “audio stream input-output”) is a technology designed for professional work with sound in the Windows environment; in particular, it reduces latency and improves the accuracy of the audio stream. If you do not plan to seriously engage in recording, mixing tracks, etc., most likely you will not need this function, but for musicians, sound engineers and other similar professionals, it can be very useful. The ASIO standard provides both software and hardware requirements; therefore, to fully use it, you must have a compatible audio card.

mini-Jack (3.5 mm)

The number of inputs in the design of the sound card using 3.5 mm mini-Jack connectors. This connector, usually used to transmit an analogue signal, is one of the most popular in modern audio technology. Speaking of inputs, it's worth noting that most computer microphones are designed to plug into the 3.5mm jack; this also applies to separate microphone plugs on headsets. At the same time, the specific purpose of the mini-jack sockets in different sound cards may be different; Moreover, in some models, the same socket can be reconfigured and even change its purpose (from input to output and vice versa). These points, usually, are specified in the characteristics.

Using a simple adapter, you can also connect a 6.35 mm plug (Jack) to the 3.5 mm jack.

Optical S/P-DIF

The number of S/P-DIF optical outputs provided in the design of the sound card.

S/P-DIF is a digital audio transmission standard, including multichannel, quite widespread in home acoustics. At the hardware level, this standard has two versions — coaxial (see below) and optical, which is discussed here. The TOSLINK fiber optic cable used for this type of connection is highly resistant to interference: electromagnetic pickups do not interact with the light pulses that transmit the signal. On the other hand, such a cable is more expensive than coaxial electrical wire and requires careful handling — strong pressure or a kink can damage the fiber.
