Abstract

La présente invention concerne un système de renforcement de la stéréo, qui traite la composante différentielle de signaux produite par deux signaux d'entrée, gauche et droit, pour créer une image stéréophonique élargie, qui est reproduite par deux haut-parleurs ou par un système acoustique d'ambiance. Le traitement de la composante différentielle des signaux se fait par une égalisation caractérisée par l'amplification des gammes basse et haute de fréquences audibles. Le signal différentiel qui est traité est combiné à un signal somme, produit à partir des signaux d'entrée gauche et droit, et aux signaux d'entrée gauche et droit d'origine, afin de créer des signaux de sortie gauche et droit renforcés.
