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.

Additional power

The need to connect additional power to the sound card.

Most of both internal and external (see "Type") sound cards are powered directly through the connection connector (see "Connection interface"). At the same time, for normal operation of advanced models (for example, audiophile and gaming, as well as some DACs; see "View"), this power may not be enough, which requires an additional power source. In internal audio cards, it is carried out from the computer power supply, in external ones — directly from the 230 V network.

Dynamic Range

The dynamic range of a DAC is the ratio between the loudest sound that the converter can produce and the quietest. The wider the dynamic range — the richer the sound will be, the lower the likelihood that quiet sounds that complement the overall picture will be muffled during conversion. At the same time, it is worth noting that almost all modern sound cards provide a dynamic range that is quite sufficient for comfortable everyday use, and in many models this parameter may not be indicated at all. It is worth paying attention to it when choosing an advanced specialized audio card — for example, a gaming one (see "View"). The minimum for professional models is 90 dB, but in fact, among similar solutions, this figure is usually 120 dB or more.

Signal-to-noise ratio

This parameter determines the ratio of the "clean" sound produced by the DAC at the output to all extraneous noise. As such, it is a pretty strong indicator of sound purity. According to the signal-to-noise ratio, DACs in modern sound cards can be divided as follows:

up to 90 dB — initial level;
90-100 dB — average level, advanced "home" models;
more than 100 dB — professional level.

Max. sampling rate

The highest sampling rate that the analogue-to-digital converter (ADC) of a sound card can provide when digitizing sound. Without going into details, we can say that the role of this parameter is almost completely similar to the bit depth described in the paragraph above. And its standard values, found in modern audio cards, correspond to the following sound quality indicators:

44.1 kHz — Audio CD;
48 kHz — DVD
96 kHz — DVD-Audio 5.1
192 kHz — DVD-Audio 2.0 (two-channel audio has a higher sampling rate than multi-channel audio for a number of reasons), the highest value in modern consumer-grade sound cards.

Signal-to-noise ratio

The signal-to-noise ratio provided by the analogue-to-digital converter (ADC) of the sound card in the processed signal. For more information about this ratio, see the paragraph of the same name above. Here we note that in domestic use it does not play a decisive role, but if you plan to record sound in good quality, you should choose a card with a high value of this indicator.

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.
