A stereo technique (or stereophonic sound) is a method of sound reproduction that uses two or more independent audio channels to create a spatial perception of sound, simulating multi-directional positioning. The system encodes, transmits, or reproduces separate signals for distinct channels (typically left and right), and a playback system renders these through separate speakers positioned to exploit human binaural hearing — using interaural time differences, interaural level differences, and spectral filtering by the pinnae — to produce a convincing soundstage. Parameters: minimum two discrete channels; channel count may exceed two (surround, ambient noise control, spatial audio); persistence through standardization in recording, broadcasting, and consumer electronics infrastructure.

Definition
Why it is in scope
A human-made technique for sound reproduction using two or more independent channels to create spatial perception, built to persist as a standard in music, film, and broadcast audio.

Stereo is a human-made sound reproduction technique built and maintained for the sake of audio engineering practice: it provides spatial soundstage creation for recording, mixing, mastering, and playback, with parameters for channel count and binaural rendering. Servant points at master per Law 8d.
- audio-processingINSTANCE_OF →
stereo is a specific technique of audio-processing that uses two channels to create spatial imaging; it is a particular instance of the broader audio-processing construct.
- cmrsb393a00miollhxpcc7bkzDEPENDS_ON →
Stereo sound reproduction depends on signals: the technique requires audio signals as its input medium — without signals to carry left/right channel information, stereo operation ceases. Remove signal and stereo has nothing to reproduce.
