Features

Ordinary. This category includes all sound cards that do not have a pronounced specialization and do not belong to any of the types described below. Usually, they have a set of characteristics of an entry-level or intermediate level and are designed for simple everyday tasks: listening to music and game sound through ordinary speakers or headphones, communicating on the Web through a microphone, etc. Conventional sound cards are equipped with both digital-to-analogue and analogue-to-digital converters, they can be either internal or external.

Audiophile (Hi-Fi). Sound cards designed for lovers of high-quality sound; they can also be useful for professionals who are engaged in professional audio processing and need the most accurate reproduction of the received signal. Accordingly, models of this type are distinguished by high build quality, advanced components, as well as the presence of additional equipment, an abundance of interfaces and advanced customization options (both software and hardware, including even the ability to replace individual circuit components). However, these cards cost accordingly.

Gamer's. Sound cards originally designed as components for advanced gaming systems. Accordingly, the main purpose of such models is high-quality transmission of game sound, including three-dimensional and multichannel. Typically, gaming audio ca...rds are equipped with advanced DACs and support various special standards (see below); in addition, they may have additional equipment such as remote control modules (see below). The vast majority of models of this type are made internal, but they often have a rather original design (which is useful for modding enthusiasts who use transparent cases).

— CAP. Abbreviation for "Digital to Analogue Converter". Usually, this term refers to the constituent element of a sound card, but in this case it refers to a separate type of audio cards, the distinguishing feature of which is the absence of an analogue-to-digital converter (ADC). Accordingly, DACs are only capable of transmitting sound from a computer to headphones, speakers, etc., and cannot be used to digitize sound from a microphone or other external signal source. Note that this category includes a variety of models — from the simplest USB-headphone adapters, the size of a flash drive, to advanced audiophile-class solutions.

Audio interface. A kind of opposite to the DAC described above: audio interfaces are designed primarily to digitize the sound coming to the input (for example, from a microphone or an electric guitar). Accordingly, they are not only necessarily equipped with analogue-to-digital converters — usually, these ADCs have very advanced characteristics and extensive sound tuning capabilities (and in some models even hardware switches are provided for this). At the same time, audio interfaces can also work in the digital-to-analogue audio conversion mode (in other words, to output sound to headphones/speakers). The cost of such devices is usually quite high, so it makes sense to purchase them only for those who plan to work a lot with sound recording.

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.

Mac compatibility

Ability to work sound card with Mac computers.

Mac (Macintosh) in this case can be attributed to both the eponymous line of desktop computers manufactured by Apple and MacBook laptops. Both of them have certain hardware differences from "regular" PCs and laptops, in addition, they were originally created for Apple's own MacOS operating system. All this led to specific requirements for peripheral devices, including and sound cards — not all models are able to work normally with a Mac. Therefore, if you purchase a sound card for such a computer or laptop, you should make sure that Mac support is directly claimed for the selected model.

Note that Apple products have very limited possibilities for replacing internal peripherals by the user, and sound cards are not included in the list of replaceable components at all. Therefore, Mac-enabled models are usually referred to as external (see "Type").

DAC resolution

The bit depth of the digital-to-analogue converter (DAC) of the sound card. In this case, DAC refers to a part of the circuit that converts digital sound data (machine code) into analogue pulses that are fed directly to an external device — speakers, headphones, etc. The bit depth is one of the main parameters (along with the sampling frequency) that describes the quality of the DAC: the higher it is, the more reliable the sound will be reproduced, the less distortion will be introduced into it during conversion.

16-bit DACs usually have entry-level sound cards — this is enough for good sound quality. In other cases, 24-bit converters are most common, and even for advanced models, in particular gaming ones (see "View"), they are almost mandatory.

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.

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.
