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 i...s supported 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.

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.

iPhone/iPod/iPad

Ability to use a sound card for direct playback from portable Apple devices — iPods, iPhones and iPads. The connection is carried out through a proprietary interface; this not only improves the sound quality, but also provides some additional features (for example, you can switch the track not on the gadget itself, but through the sound card control system, which is often more convenient). An audio card with this feature can be very useful if you plan to frequently listen to music from Apple devices.

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.

Dynamic range

The dynamic range of an ADC is the ratio between the loudest and quietest sound that the converter is able to perceive and process. The larger this parameter, the more complete the picture of the sound converted to digital format will be, the less quiet details (which, nevertheless, affect the overall sound) will remain when digitizing “behind the scenes”. At the same time, we note that this parameter is critical only for professional recording, and therefore it is indicated in the characteristics quite rarely, usually only in models of the corresponding specialization (in particular, audio interfaces, see "View").

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.

RCA

The number of inputs with RCA connectors in the design of the sound card.

The RCA connector itself can be used for different types of signal, however, in this case, the simplest linear interface for analogue audio transmission is meant. In such an interface, one connector allows you to transmit only one channel of sound. Therefore, the minimum and, in fact, the standard number of RCA inputs in modern sound cards is two, for the left and right stereo channels. A larger number is extremely rare, in separate high-end audio interfaces (see "Type"), but in such models the number of connectors is also a pair.

Separately, we note that this input should not be confused with coaxial S / P-DIF (see below): although the latter also uses an RCA jack, however, it is fundamentally different in signal format and has specific cable requirements.
