Shopping Guide: What you should know about sound cards

When buying a sound card, it is essential that you understand how it works, what features are most important, and what advantages you get from installing one on your computer.

So that you can solve all the doubts you may have about it, we have prepared this section.

What are sound cards?

Sound cards are internal or external electronic devices responsible for processing audio in digital format.

They are often integrated into the same motherboard, although when this is the case their performance is usually quite limited.

Dedicated sound cards, on the other hand, are designed for more demanding applications and to provide superior sound quality.

What are the functions of the sound cards?

The main function of the sound cards is to manage the audio within the personal computer.

They are responsible for receiving the sound, digitizing it if necessary, processing it and sending it to the output device in the desired format.

Thus, their most important tasks are:

What are the components of a sound card?

Besides knowing the functions that a sound card performs, it is interesting to know its different components and the importance that each one has in the performance of the card.

In this way, you will be able to understand much better the specifications of the different models.

Let’s see the most important ones:

  • Processor/DSP: it is the component responsible for generating the bit string that makes up the sound.
  • DAC/Digital-to-Analog Converter: converts a digital signal into the analog signal you hear in your speakers or hearing instruments.
  • ADC/Analog-to-Digital Converter: as its name indicates, it does the inverse function to that of the DAC and converts analog signals into digital signals.
  • Amplifier: whose importance is fundamental in the performance of any card, especially if you are going to use hearing aids. It is the component in charge of amplifying the sound coming from the DAC before it reaches any of the card’s outputs.

What are the advantages and disadvantages of sound cards?

It’s always good to know what the pros and cons of a sound card are.

That’s why we tell you the many advantages and disadvantages offered by dedicated sound cards in the following chart:

For whom is it advisable to buy a sound card?

Not every user needs a computer with a dedicated sound card.

If you use the computer mainly for office tasks and to watch some series or movies occasionally, you have more than enough with the one integrated in the motherboard.

However, if you want to set up a powerful PC gamer or a PC for audio editing, you need a dedicated card.

The same is true if you need more audio channels.

A dedicated card is essential if you have professional speakers or headphones and want to enjoy the best sound quality.

You may also want a dedicated card if your computer’s motherboard is more than five years old, as in that case it probably does not have good protection against interference.

What types of sound cards are there?

There are usually three different types of sound cards: internal sound cards, audio interfaces and USB sound cards. Let’s see what the main features of each are.

  • Internal sound cards: usually connected to the motherboard via PCI or PCIe connections. They require their own drivers.
  • Audio interfaces: these are more focused on professional applications and production, so they often offer superior performance to internal or external sound cards for home use. They are usually connected via USB connections.
  • USB sound cards: they usually offer the same features as internal sound cards, but connect through a USB port. Therefore, they also require their own drivers.

Purchase criteria

The best way to get the right sound card is to have the right purchase criteria. We have used the following to develop our selection of recommendations.

Use you will make of the card

You don’t need the same type of sound card to replace your simple computer’s sound card as you need for professional applications.

That’s why this should be your first filter. In the following table, you can see some recommendations about it.

Audio Channels

The number of channels on the sound card determines the number of speakers that can be connected to the sound card.

In addition, if you use hearing aids, a larger number of channels will also allow you to emulate or position more directions. In this way, you will be able to enjoy a much more precise sound.

Two audio channels are the minimum value required for stereo sound. However, you will most likely want to enjoy 5.1 or even 7.1 surround sound.

These six or eight-channel audio systems use five or seven full-band channels and one narrow-band low-frequency channel, which is occupied by the subwoofer.

Bit depth or sound resolution

The number of bits reflects the quality of sound the card can sample or the spectrum of sounds the system is capable of emitting.

Most commonly it is between 8 bits and 24 bits.

A 16-bit card, which is the minimum value considered nowadays, is able to distinguish 32,000 different sound intervals or shades.

The value considered ideal is 24 bits. Anyway, we have to take into account that the bits are going to be limited by the capacity of the human ear.

From a certain value, it does not make any sense to expand them because, unfortunately, we could not appreciate that increase in sound resolution.

Sample rate and SNR

Sample rate is the process used to record sound, or in other words, to convert analog information into digital information (in binary language).

Its frequency is measured in kilohertz (kHz). The most common values range from 44.1 kHz, which gives a sound quality equivalent to that of CDs, to 192 kHz.

The SNR (Signal to noise ratio) is related to the buzz or background noise heard when a speaker or headphones are connected.

Thus, the higher the SNR value (measured in decibels), the less hum is heard when no sound is being played and therefore the sound quality is better.

Input and output connections

Depending on the use you are going to make of the equipment, you will need the card to integrate some input and output connections or others.

These are some of the outputs you may want to include in your sound card.

  • Line Outputs: to connect active speakers or amplifiers, as it is usually an output that comes with a minimum amplification. It is usually of three types: 3.5 mm mini-jack, through RCA connectors or 3-pin XLR balanced connectors.
  • Headphone output: allows connection of headphones via a jack cable. This is an output with an amplified signal.
  • Speaker Outputs: These are audio outputs specifically for speakers. They can be color-coded to indicate which speaker they are for.
  • Optical connection output: this is a high quality digital connection to which a fibre optic cable must be connected. The main advantage they offer is that they have a high resistance to signal loss along the cable.
  • S/PDIF output (Sony-Philips Digital Interface) – This is a digital audio connection that, among other things, allows connection to an amplifier via an RCA cable.
  • MIDI Output: This is used to connect digital instruments that use a MIDI language. In this way, it is possible to play a melody on the instrument.

On the other hand, some entries you may need to include in the sound card are,

  • Line input: usually a 3.5 mm mini-jack, which is a standard that offers average sound quality. In mini-jack connections the two stereo channels go together. It allows to connect any device with line output.
  • MIDI Input: Used to connect digital instruments that use a MIDI language. Specifically, to pass the sound from the instrument to the computer.
  • Microphone Input – This is an analog audio connection for connecting a microphone. It is usually a 3.5 mm or 6.3 mm (XLR) jack input. However, if you plan to connect a condenser microphone you have to make sure that it is compatible, as they require a potential of 48 V (volts).

Many users do not need a dedicated sound card in their computers.

They have enough with the basic features that come integrated into the motherboard.

However, if you want to enjoy better sound quality for home theater, gaming or if you want to use your equipment for professional applications, you must have one.

In order to choose which one you need, you have to think about the use you are going to make of the equipment.

If you need one that allows you to hold video conferences with good quality sound, an external low-end USB card is enough.

To set up a home studio at home, you should opt for an input or mid-range audio interface.
