A sound card is a valuable tool for gamers, multimedia experts, and regular everyday people. The history of the soundcard is brief, but it is one of the chief components used in computers. Also known as an audio card, A sound card is an internal expansion card that converts computer data into electrical audio signals and converts electrical audio signals into computer data. In other words, a sound card transcribes digital signals into analog signals.
The sound card works as an audio processor in the computer. The digital or analog signals are received at the .card’s input. They are digitally interpreted as algorithms which are then interpreted as waveforms and generate a sonic signal in the output of the computer sound card. The sound card directs all audio on the computer. It is installed on the computer and possesses a setup of hardware properties with their respective device drivers.
Surround sound and connectors
Surround sound is an audio output in which sound seems to surround the listener by 360 degrees. It can work either as a digital or analog system.
Surround sound consists of a set of stereo front speakers and a set of surround speakers. It also includes a center channel. A speaker is placed between the front speakers that help reproduce dialogues in movies. Typically, 5 speakers are involved, but more speakers can also be added.
Evolution of surround sound
Early surround sound formats like Dolby Surround, and Dolby Pro Logic used Matrix as their base. Dolby digital 5.1(the digit before decimal indicates the number of speakers, and after the decimal indicates the number of the subwoofer) was stereo and had high bandwidth.
It added the feature of a low-frequency effects channel. Digital DTS (Digital Theatre System) first hit theatres with Jurassic park by providing digital surround-sound mixing services for movie production. It had a higher bit rate and delivered more audio information.
Dolby and THX collaborated to form a 6.1 channel. The 6th speaker was added and called a Back surround. DTS introduced DTS-ES Discrete and DTS-ES Matrix. In the former, the specific sound information was programmed onto a DVD or Blu-ray disc. At the same time, in the latter, the matrix uses the same principle as Dolby Digital Ex to gather information from the surrounding channels.
The most advanced surround sounds by Dolby are Dolby Digital Plus and Dolby True HD. They are of two different 7.1 surround versions. Dolby Digital Plus applies lossy compression to all the discrete audio channels. In Dolby True HD, no compression is involved. DTS also has two 7.1 versions, which differ in the same manner as Dolby’s versions. They also have the same properties as Dolby’s.
Surround sound like Audyssey DSX works on mixing 5.1 and 7.1 signals to add more channels. It also allows for 11.1 channels of surround sound. Audyssey DSX 2 allows up mixing of stereo signals to surround sound.
3D surround, also known as object-based surround, has revolutionized the history of surround sound.3D offers the best description of this technology because of its ability to make sounds feel as the viewers are moving through space.
What are connectors and why are they needed?
To connect the surround sound with your TV, you will need different kinds of connectors. There will be the audio out labeled on the backside of your TV with one of the following types of audio output. HDMI slot, AV ports, or optical port.
HDMI, optical, or AV cables are needed to connect your receiver to the TV. HDMI and optical cables can transfer the digital audio from one device to another. There is no difference in their performance when it comes to transferring multi-channel audio like Dolby digital.
The difference between them is that HDMI cables can transfer higher resolution audio while Fiber optic cables cannot. HDMI can also pass video signals while Fiber optic can’t.
AV cables are useful for basic audio, and all receivers should have them because all speakers needed them to connect to the receiver.
Let’s see some of the examples of these connectors.
Digital Coaxial Cables are available in different lengths. Each Digital coax sends 5.1 audio to the back of your device, i.e., your digital set-top box or DVD player, to your receiver or Amplifier to get 5.1 channel audio.
When you Combine your digital optical cables with a correctly calibrated amplifier, receiver, or surround sound to receive true surround sound, you can see the amazing results of Digital optical cables.
Dialogue comes from the center speaker only, and bullets are shot from speaker to speaker one at a time, and it sounds like you are really at the cinema.
RCA AV cables
They are used for transmitting multichannel analog audio signals. For example, a surround soundtrack on a DVD or Blu-ray. They can be useful if you don’t have digital HDMI or optical cables. They do not support digital audio signals.
HDMI cables like Go Pro Hero 3, micro HDMI cable, and High-Speed HDMI Cable with Ethernet. GoPro can plug into any monitor or TV with HDMI cables and give 1080 resolution and crystal-clear pictures.
Micro HDMI cable is useful for tablets. And HDMI cable with Ethernet adds high-speed networking to an HDMI link, allowing users to take full advantage of their IP-enabled devices without a separate Ethernet cable.
Integrated VS Dedicated sound card
A few years ago, integrated sound cards were not good quality, and a computer geek would suggest buying a dedicated sound card, especially if you are a gamer.
With the advent of modern technology, computers have become small and light in weight. The chips in the computers have become small, allowing other high-quality components to fit in a computer. Static and interference are rarely a problem these days, and most users are just satisfied with the output on most two speakers’ setup.
By using an integrated sound card, you will save a lot of money because with dedicated sound cards, not only do you have to expend money on the card, but you will need new speakers and a headset.
These days every computer has a built-in sound card. Companies like Asus and Gigabyte have created models with 7.1 channel output which is more than enough for your basic sound needs.
These integrated sound cards are handy, but dedicated cards still have importance in the computing world. Most integrated cards have 5.1 or 7.1 channels, but a DVD or game must contain surround sound signals for this to work.
Compared to a dedicated card, most integrated cards cannot generate 5.1 or 7.1 signals on their own from a stereo signal. Dedicated sound cards have several modern and useful features that produce better sound quality.
With the integrated soundcards, you can listen to the same music or play the same games as a dedicated sound card, but you will not get the same level of sound quality.
Dedicated sound cards have a high signal-to-noise ratio, 192-kHz resolutions, additional APIs,24bit sample rates, and low harmonic distortion. These features make the sound card worth buying.
Most people probably use a dedicated soundcard due to its better analog output and lower latency. Lower latency is required if you create music live.
The higher frequency output of 96KHz may be why people prefer to use a dedicated sound card instead of an integrated sound card. A higher frequency helps to get the lower latency.
Make sure that the frequency of your dedicated sound card matches that of your source, or else your OS will mix the sound.
Integrated sound cards have become much more advanced, and dedicated sound cards are less important than before. However, your preferences decided which one is important.
Integrated sound cards are good enough for regular users, and dedicated sound cards are good for audiophiles. Also, integrated sound cards are cost-effective, while dedicated sound cards are expensive. It’s all up to you which one you desire according to your needs.
Integrated sound card
When your device has its built-in sound card, and you do not need an external or additional sound card, this is known as an Integrated sound card.
Dedicated sound card
When you use an external sound card with your device, it is known as a dedicated sound card.
Why were the sound cards created?
The sound card was created because, for a long time, the sound came from an integrated source on the computer’s main motherboard. This sound was in simple beeps, so programmers began to create music with these beeps for games.
The gamers had little control over the game’s sounds, and it was very boring for them. Music composition was also the other reason for which sound cards were needed. Ad-lib was one of the first manufacturers of Sound cards for IBM computers.
An important turning point in the history of the sound card was the invention of the Sound Blaster card by Creative Labs. The sound blaster was just like the Ad-lib sound card, but with the addition of a sound coprocessor that records and playback the digital audio, a game port for the insertion of a joystick, and the ability to interface with the MIDI equipment.
The sound blaster overtook the Adlib because, with the same price, it provided more features and captured the buyer’s attention.
The Birth of sound card:
An industry Standard Architecture Bus (ISA) was introduced in the early 1980s, initially 8bit but later expanded to a 16bit version. Later it was replaced by the faster Peripheral Component Interconnect (PCI), which was initially 32 bit and then expanded to 64 bit after few years.
Accelerated Graphics ports(AGP), which were developed as an alternative to PCI standards, were better than PCI in providing the dedicated bus for graphic data and capable of providing graphics faster and better than PCI.
By 2004, both PCI and AGP were succeeded by PC Express. The PC Express was better because, contrary to the earlier PCI standard, it does not use a parallel bus structure but a network of serial connections directed by the computer motherboard, making it more efficient and faster—these soundcards costs between 80 to 100 dollars.
In the beginning, sound cards were large with volume controls on them. The later sound card used became more efficient by using a higher band shift. The introduction of Microsoft windows proved to be a stimulus for better sound cards because it introduced hardware interface protocols for the cards.
With the advances in technology, manufacturers have made many improvements in the onboard audio of the motherboards. The user can fulfill their needs like watching movies, playing games and listening to music without sound cards.
But if you are doing sensitive sound work and want the best of the best, you can use a sound card. An external DAC (Digital to Analogue Converter) is also suggested for better audio quality. Some people think it’s better to use an External DAC instead of a sound card, but both have significance and drawbacks.
The sound card is placed inside the PC’s case and exposed to all the electrical noises and interferences. DAC is placed outside the PC and thus has less noise effect and better sound quality. However, the cost of the DAC is higher than that of sound cards.
If you get a high-quality sound card, you get the sound with more clarity. An advantage of the sound card over DAC is the software it possesses. This software has features that remove the messy audio of the surroundings and add effects to the vocals, while the DAC does not possess such features.
However, digital signals are sent directly in the external DAC, so there is less chance of interruption of noise from your computer. A good quality sound card efficiently reproduces virtual surround sound for the computer, while the external DAC cannot do this.
A USB DAC is portable, and you can easily carry it and insert it on your laptops, notepads, and headphones. If your DAC has a built-in headphone amplifier, you can hear amazing quality audio on your headphones.
The high-quality sound card also possesses the feature of a built-in headphone amplifier. You can even use both DAC and the sound card to get the best quality of sound.
Concluding the above comparison between DAC and sound card, it is necessary to keep in mind your preferences and needs while buying any one of them. Sound card, however, is less costly than the external DAC.
Evolution of Sound card
Sound cards have evolved tremendously in recent years. The manufacturers have tried their best to make the buyers interested in their products.
They have made many advancements in sound cards that make users believe that they have not gambled but rather invested their money in a product that will give them desirable output. Sound cards have again become better than the onboard audio and worth buying for the audiophiles.
In 2019, sound cards with the name AE9 dominated the market. The AE9 sound card costs about 300 dollars replaces a lot of audio equipment. It consists of a sound card that goes into the PC and an Audio Control Module (ACM) placed on your computer’s desk, connected by a mini HDMI cable.
The ACM acts as a headphone as well as audio interphase. Behind the box, there are phono inputs, where you can plug auxiliary devices like smartphones and MP3 players. The soundcard itself has 4 lines out port and an optical in and out that allows the connection of a full set of 5.1 surround- sound speakers.
You can quickly and accurately adjust playback volume as you desire with the ACM’s wheel. This feature is handy in games like Counter-Strike, where the footstep of a criminal can lead you to victory, or else you will get a knife in the back.
Just imagine, if you are playing a game and an ambulance pass by your flat, this feature will enable you to amplify the volume without losing your focus.
The AE-9 contains a scout mode that raises the volume of all sounds to a certain limit. It is beneficial for those who play in a chattering environment. If you notice a static or other interference on playback or recording, you can consider using AE-9.
Although motherboards have improved a lot, cheap models can still introduce annoying sounds. Particularly when you listen to music at low volume or record a podcast, or live-stream your gameplay, these sounds can annoy you a lot.
AE-9 has a clean line feature, which has a function to correct the power supply ripple caused by a high-end CPU.
In 2022, sound cards like ASUS Essence STX II, Creative sound blaster Z, Creative sound blaster Omni, Sound Blaster Audigy Fx, and Rx are ruling the market and are among the most favorites of the users.

But the question is, Do sound cards worth it? And do users need sound cards? The sound cards have extra ports and other alluring features that make users think they have gotten everything they needed. An audio lover will surely say that a sound card is worth the cost, but the scene may be different for other people.
Gamers particularly use soundcards to offload work from their CPU. In this way, they get better framerates during gaming. For gamers, this thing matters a lot.
Sound card improves sound quality, and this is indeed useful in games where the sound of surroundings helps identify and locate your enemy.
Sound quality matters in games like Bioshock2, Portal 2, and Dead space. Sound cards help the gamer to engage in the game and to play it joyfully and enthusiastically.
But if you are not a gamer, these things will not matter to you. The onboard audio from your computer motherboard is good enough for everyday use.
But if you need a sound card, you should go for the recent and upgraded sound card, which has good quality because a cheap sound card will not make any difference.
Considering the above features that the top and the latest sound cards possess, it is suggested that they are worth buying for audiophiles like gamers, YouTubers, podcasters, and anyone in love with the clarity and the purity of the sound.
The manufacturers have tried their best to make their products desirable for their users. The audiophiles can get the modern and desirable features in all the models dominating the market in 2022. (as I have mentioned above, each model with its features).
But for the other people, onboard audio is enough. While buying the soundcard, one should keep in mind that he needs new speaker amplifiers and other inputs; if your speakers and headset are not quality, the soundcard will not be useful.
