Abstract

En anordning for generering av et kodet stereosignal fa en fierkanalfiemstilling som omfiatter en flerkanaldekoder (11) som genererer tre eller fiere flerkanaler fira minst en basiskanal og parametrisk infiormasjon. De tre eller fiere fierkanaler er utsatt fior hodetelefionsignalprosessering (12) fior å generere en ukodet fiørste stereokanal og en ukodet andre stereokanal som så er fiorsynt til en stereokoder (13) fior å generere en kodet stereofil på utgangssiden. Den kodede stereofil kan bli tilfiørt enhver passende spiller i fiorm av en CD-spiller eller en maskinvarespiller slik at en bruker av spilleren ikke bare får et normalt stereoiimtrykk men også et flerkanalsiimtiykk.
