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.

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").

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.

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.

ADC resolution

The bit depth of the analogue-to-digital converter (ADC) of the sound card. An ADC is a module that encodes an analogue audio signal into a digital format; it is he who is responsible for transmitting sound "to the computer" — for example, through a microphone when communicating via Skype or from a guitar pickup when recording a track. The bit depth is one of the main parameters that describe the quality of the ADC: the higher it is, the less distortion will be introduced into the digitized sound and the higher the maximum possible quality of its recording. Of course, the properties of the actually recorded sound will depend on many other things (hardware, software, settings, file format, etc.), but for high-quality recording, you will definitely need a good ADC.

A bit depth of 16 bits is considered quite sufficient for everyday use, however, even fairly simple models of audio cards are increasingly acquiring 24-bit ADCs.

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.

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").
