They can be an excellent option for mobile recording, live performances, or situations where a quick and easy audio upgrade is needed. External sound cards often include additional features like microphone preamps and instrument inputs, making them versatile tools for musicians and content creators.

3. Audio Channels and Surround Sound

The number of audio channels a sound card supports determines the type of surround sound it can produce. The most common configurations are 2.0 (stereo), 5.1, and 7.1. A 2.0 sound card provides stereo sound, which is suitable for basic audio playback and some gaming scenarios. A 5.1 sound card supports five main channels (front left, front right, center, rear left, rear right) and a subwoofer channel, creating a more immersive surround sound experience. A 7.1 sound card adds two additional rear channels, further enhancing the surround sound effect.

If you plan to use a surround sound speaker system, you’ll need a sound card that supports the corresponding number of channels. For headphones, some sound cards offer virtual surround sound, which simulates a surround sound environment using software algorithms. This can provide a more immersive gaming or movie-watching experience, even with just a pair of headphones. Technologies like Dolby Atmos for Headphones and DTS Headphone:X offer advanced virtual surround sound processing, creating a more realistic and spatial audio experience.

4. Signal-to-Noise Ratio (SNR) and Total Harmonic Distortion (THD)

Signal-to-noise ratio (SNR) and total harmonic distortion (THD) are two important specifications that indicate the audio quality of a sound card. SNR measures the ratio of the desired audio signal to the background noise. A higher SNR indicates cleaner audio with less noise. THD measures the amount of distortion in the audio signal. A lower THD indicates more accurate audio reproduction.

For critical listening, such as music production or audiophile listening, a sound card with a high SNR (100dB or higher) and a low THD (0.001% or lower) is recommended. For gaming and movie watching, these specifications are less critical, but a sound card with a decent SNR and THD will still provide a noticeable improvement over integrated audio.

5. Digital-to-Analog Converter (DAC) and Analog-to-Digital Converter (ADC)

The digital-to-analog converter (DAC) converts digital audio signals into analog signals that can be played through speakers or headphones. The analog-to-digital converter (ADC) performs the opposite function, converting analog signals (such as those from a microphone) into digital signals that can be processed by the computer. The quality of the DAC and ADC has a significant impact on the audio quality of the sound card.

A high-quality DAC will produce cleaner, more detailed audio with a wider dynamic range. A high-quality ADC will capture analog signals with greater accuracy, resulting in better recordings. If you plan to do any recording, such as voiceovers or music, a sound card with a good ADC is essential. For audiophiles, the DAC is particularly important, as it determines the quality of the audio they hear through their headphones or speakers.
