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.— 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.
