Comparison Creative Sound Blaster X3 vs Creative Sound Blaster X-Fi Surround 5.1 Pro

— Regular. This category includes all sound cards that do not have a clear specialization and do not belong to any of the types described below. Generally, they have a set of basic or mid-level characteristics and are intended for simple everyday tasks: listening to music and game sound through regular speakers or headphones, online communication via microphone, etc. Regular sound cards are equipped with both digital-to-analog and analog-to-digital converters and can be either internal or external.

— Audiophile (Hi-Fi). Sound cards designed for lovers of high-quality sound; they may also be useful for professionals engaged in professional audio processing who require the most accurate reproduction of the received signal. Accordingly, models of this type are distinguished by high build quality, advanced components, and additional equipment, a variety of interfaces, and extended configuration capabilities (both software and hardware, including even the possibility of replacing individual components of the circuit). However, such cards are priced accordingly.

— Gaming. Sound cards originally created as components for advanced gaming systems. Accordingly, the main purpose of such models is the high-quality transmission of game sound, including 3D and multi-channel sound. Usually, gaming sound cards are equipped with advanced DACs and support various special...standards (see below); furthermore, they may have additional equipment like external control modules (see below). The vast majority of models of this type are internal, but they often have rather original designs (which will be useful for modding enthusiasts using transparent cases).

— DAC. Abbreviation for "digital-to-analog converter." This term usually refers to a component of a sound card, but in this context, it refers to a separate type of sound card, whose distinctive feature is the lack of an analog-to-digital converter (ADC). Consequently, DACs can only transmit sound from the computer to headphones, speakers, etc., and cannot be used for sound digitization from a microphone or other external signal sources. Note that this category includes a variety of models — from basic "USB-headphone" adapters, the size of a flash drive, to advanced audiophile-class solutions.

— Audio Interface. A kind of opposite to the above-described DAC: audio interfaces are primarily intended for digitizing incoming sound (e.g., from a microphone or electric guitar). Consequently, they are not only necessarily equipped with analog-to-digital converters — generally, these ADCs have very advanced characteristics and extensive sound adjustment capabilities (and some models even provide hardware switches for this). At the same time, audio interfaces can also work in the mode of converting digital to analog sound (simply put — outputting 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.

The main interface used to connect a sound card to a computer or other device.

Like the sound cards themselves, the interfaces used in them are divided into internal (PCI, PCIe) and external (USB-A, USB-C, FireWire, Thunderbolt, 3.5 mm mini-jack, Bluetooth). Here's a more detailed description of each of these options:

— PCIe. The main modern interface for connecting internal peripherals (including sound cards) to computer motherboards. It is used in most internal type models (see above). The main advantage of PCIe solutions is that connectors for their connection can be found on almost any modern "motherboard". True, these connectors may be needed for other components — graphics cards, TV tuners, or even SSD drives; however, even the simplest motherboards usually have several PCIe slots, so this point cannot be considered a serious disadvantage.

— PCI. An interface for connecting expansion cards to the PC motherboard. It is the predecessor of PCIe, has significantly lower bandwidth and more modest capabilities, so overall it is outdated. Nevertheless, motherboards with such connectors, and sound cards for the PCI interface (including quite advanced ones), continue to be produced. This is because working with sound requires comparatively low bandwidth; and installing a so...und card in a PCI slot leaves PCIe connectors free, which may be required for components more demanding on connection speed. In any case, before purchasing such a sound card, it does not hurt to separately ensure that there is a connector for its connection on the "motherboard".

— USB-A. Connection through a standard USB port. Until recently, it was the most popular interface for external peripherals, found in almost all PCs and laptops. Most external sound cards were made for USB. The disadvantage of this connection method is that USB connectors may be needed for other devices, which creates problems with a small number of ports and an abundance of peripherals. On the other hand, such situations arise not so often, and to solve them, it is enough to have a USB hub on hand.

It should be noted separately that full-size USB ports in modern PCs and laptops have been replaced by more compact USB-C (see below).

— USB-C. A peripheral connector with a symmetrical contact group, which often replaces full-size USB ports on modern PCs and laptops. Many new models of external sound cards are made for this interface. The only exceptions are individual Thunderbolt devices (see below) — for them, Thunderbolt is indicated as the peripheral connection port, not USB-C.

— Thunderbolt. A universal peripheral port mainly used in Apple computers and laptops. It is important to consider that different generations of Thunderbolt differ in the type of physical connector: versions v1 and v2 use the miniDisplayPort socket, version v3 uses the USB-C socket. So when choosing a sound card with such a connection, it is necessary to clarify this point. On the other hand, Thunderbolt versions with different connectors are fully compatible with each other through corresponding adapters.

— FireWire. Also known as IEEE 1394. An interface for external devices that was somewhat popular some time ago but has now almost fallen out of use.

— 3.5 mm (mini-jack). The mini-jack is one of the most common audio connectors. However, it is usually provided as one of the audio inputs (see below) and is very rarely used as the main interface for connecting a sound card to an external device. Such a connection is mainly found in specialized gaming models, intended for use with consoles as well. In these models, the mini-jack may be combined, allowing for the connection of both a line (analog) signal via a regular electrical wire and an optical (digital) signal via a TOSLINK cable. It is worth noting that the optical interface is notable for being completely immune to external interference; it allows for transmitting multi-channel sound, but cables for such connections require careful handling.

— Bluetooth. Wireless connection following the Bluetooth standard. It is mainly found in models intended for use with smartphones and tablets — these gadgets have few wired connectors, but Bluetooth modules are almost guaranteed to be present. However, initial sound transmission is highly compressed, noticeably affecting its quality; to remedy this drawback, modern Bluetooth sound cards usually support aptX. Of course, this technology must be supported by the signal source as well — make sure of this before purchasing.

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.

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.

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.

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").

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.

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.

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.
