Usually abbreviated to stereo, a form of sound recording and reproduction which aims to reproduce a spatial aural experience, in terms of width and depth, analogous to human binaural hearing. Two microphones (plus possible additional complementary microphones) are used to record two independent representations of sound to two channels. As well as representing a domestic audio standard, stereo has been widely adopted in electroacoustic music, stereo being suited to playback over any number of loudspeakers, and therefore used in diffusion systems, octophonic systems and so on. The term is derived from the Greek stereos, meaning solid, which is the aural effect it strives to achieve.

Habituellement abrégée en stéréo, la stéréophonie est une forme d'enregistrement et de diffusion du son dont l'objectif est de reproduire l'expérience spatiale de l'écoute en terme de largeur et de profondeur et en analogie avec la perception binaurale de l'oreille humaine. Deux microphones (pouvant être accompagnés de microphones complémentaires) sont utilisés pour enregistrer deux représentations indépendantes du son sur deux canaux. La stéréo, de même qu'elle représente un standard audio hi-fi, a été largement adoptée en musique électroacoustique à travers l'utilisation de plusieurs haut-parleurs tels que les systèmes octophoniques ou autres. Le terme vient du grec “stereos” signifiant “solide”, ce qui est l'effet quelle tente de réaliser.

Spesso abbreviata nella forma contratta “stereo”, viene detta stereofonica una forma sonora registrata e riprodotta che riproduce un'esperienza aurale spazializzata in termini di profondità e larghezza, analoga all'ascolto umano binaurale. Due rappresentazioni indipendenti di suoni vengono registrate tramite due microfoni (più altri possibili microfoni complementari) su due canali. Tale tecnica, divenuta uno standard per l'ascolto domestico, è stata ampiamente adottata anche dalla musica elettroacustica, poiché la stereofonia può essere eseguita da qualsiasi numero di altoparlanti, o sistemi di diffusione, ottofonici ecc. Il termine deriva dal greco stereos che significa solido, effetto che tale tecnica di diffusione tenta di realizzare.

Usualmente abreviado como estéreo, es una forma de grabación y reproducción de sonido que busca reproducir una experiencia auditiva espacial, en términos de anchura y profundidad, análoga a la audición humana binaural. Dos micrófonos (más otros posibles micrófonos complementarios ) son usados para grabar dos representaciones sonoras independientes en dos canales. Así como representa un estándar doméstico para el audio, el estéreo ha sido ampliamente adoptado en la música electroacústica por ser adecuado para reproducirse por un número cualquiera de altavoces. Por lo tanto es empleado con diversos sistemas de difusión, como por ejemplo, los octofónicos. El término deriva del griego stereos, que significa sólido, siendo éste el efecto auditivo que intenta conseguir.
