Computer speakers can be used to create a stereo sound setup, but they are not typically designed to provide true surround sound. Surround sound systems typically consist of multiple speakers placed strategically around a room to create an immersive audio experience with distinct channels for different directions.
However, some computer speaker systems may advertise virtual surround sound capabilities. These systems use various techniques, such as audio processing algorithms, to simulate the effect of surround sound using only two or a limited number of speakers. While these virtual surround sound technologies can enhance the spatial audio experience to some extent, they are not as accurate or immersive as a dedicated surround sound system with multiple speakers.
If you're looking for a genuine surround sound experience for your computer, it's recommended to invest in a dedicated surround sound speaker system or a soundbar specifically designed for that purpose. These systems typically include multiple speakers and a dedicated subwoofer to provide the full range of audio channels required for true surround sound reproduction.
