Stereo

‘Stereo’ (or stereophonic sound) is a method of audio reproduction that aims to create the illusion of a multidirectional audio perspective.

Traditionally stereo is thought of as using two speakers, however it applies to any system using two or more speakers that aims to create the impression that sound is approaching from multiple directions.

Stereo can either be recorded ‘naturally’ using a set of microphones that captures audio from multiple directions, or it can be recreated artificially with multiple mono channels and the use of panning.
