What is Stereo and Surround Sound?

Most people confuse stereo with mono whenever the subject of audio channels arises. However, mono means a single audio source so even if you are using two speakers, the same audio signal will go into both speakers.

Stereo on the other hand uses two dedicated signals or channels – left and right.

Surround sound uses more than just two channels. It uses multiple audio channels to give you a more immersive audio experience. Surround sound multimedia speakers are awesome for multi-channel sound and intense realism. Check out our surround sound guide to learn more.
