Converting stereo audio to 5.1 surround sound involves expanding the two-channel audio signal into six channels, creating a more immersive audio experience. This process requires specialized software that can analyze the stereo audio signal and create the additional channels needed for 5.1 surround sound.

This creates a very convincing "hall" effect in the rear speakers, though it lacks the punch of true discrete remixing. stereo to 5.1 audio converter software
