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.

Max. sampling rate

The highest sampling rate provided by the digital-to-analogue converter (DAC) of the audio card. For more details on the role of the DAC, see paragraph "Bit depth" above. Here we note that the quality of its work directly depends on the sampling frequency: the higher it is, the less distortion occurs when converting sound.

Usually in sound cards there are standard values for the maximum sampling rate:

44.1 kHz — corresponds to the sound quality of 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.

Another specific point is that the quality of sound played on a computer cannot be higher than the capabilities of a sound card. In other words, if an audio file is recorded at a higher sampling rate than the audio card can provide, its sound quality will be reduced: for example, on a 44.1 kHz card, even DVD-Audio sound will sound like an Audio CD. Therefore, if you want to fully enjoy high-quality sound, you should choose a model with a high sampling rate.

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.

More features

— Headphone Amplifier. The presence of a separate headphone amplifier in the design of the sound card. Such equipment allows at least to improve the overall sound of the “ears”, as well as to implement various additional settings for such sound (for example, a separate volume control). And some headphones — primarily high-impedance Hi-Fi models — in principle cannot be used without special amplifiers.

— External control module. The presence of an external control module in the design of the sound card. Such a module is actually a control panel with a wired connection; it doesn't give you the freedom of movement that a wireless remote control does (see below), but it's cheaper and often more convenient. So, the control module does not have to be in direct line of sight with respect to the audio card, and the length of the wire is often enough to place the device at the user's hand. However the set of adjustments placed on the external unit is usually limited to the most basic settings; however, even this, usually, is quite enough for comfortable use. In addition, the control unit often provides additional connectors for connecting headphones and a microphone. Among other things, this feature is especially convenient in games — it allows you to adjust the sound without distracting from the game itself. However, other types of sound cards can also be equipped with external modules (see "View").
...
— Remote control. A remote control is included with the sound card. Do not confuse this function with the external control module described above: in this case, we mean a classic wireless IR remote control, like those used in TVs. Such a device does not necessarily cover all the capabilities of the audio adapter, however, the range of functions of the remote control can be quite extensive. On the other hand, the need to control a sound card from a distance is extremely rare, and in most cases, the mentioned external module is enough for this. So models with a remote control are not widely used.

Exit to the front panel. Ability to connect an internal sound card (see "Type") to the connectors on the front panel of the PC. To do this, a special connector (or several connectors) is provided on the board, which is connected to the corresponding connector (s) using a wire. The convenience of this feature is obvious: in desktop computers, the front panel is located closest to the user, and it is to it that it is easiest to connect peripherals that involve frequent plugging and unplugging, such as headphones and microphones. Actually, connectors for such devices are most often displayed on the front panel.

mini-Jack (3.5 mm)

The number of outputs with 3.5 mm mini-Jack connectors in the design of the sound card. It is this connector that is used by the vast majority of modern computer headphones and speakers of all price categories (although it is relatively rare in top-end technology), and it is very popular in other consumer-class audio devices. Therefore, almost all entry-level and mid-level sound cards have at least one 3.5 mm jack; the absence of such outputs is typical for specialized models (for example, DAC, see "View"). Also note that a single mini-jack output can work with a maximum of two channels, however, this interface is also used in multi-channel sound systems — in this case, the audio card is equipped with several connectors, each of which is responsible for its own part of the system. For example, for 5.1 systems, one connector is allocated to the centre, one to a pair of front channels, one to a pair of rear channels, and one to a subwoofer.

As with 3.5mm inputs (see above), this type of output can be used in a variety of ways and can even be configurable.
