Abstract

Anordning for konstruksjon av et multi-kanals utgangssignal ved å benytte et inngangssignal og parametrisk sideinformasjon, der inngangssignalet omfatter den første inngangskanal og den andre inngangskanal fremskaffet fra et opprinnelig multikanalssignal, og der den parametriske sideinformasjon som beskriver interrelasjoner mellom kanaler i det multi-kanals opprinnelige signal benytter basiskanaler for syntetisering (324) av de første og andre utgangskanaler på en side av en antatt lytteposisjon, som er forskjellig fra hverandre. Basiskanalene er forskjellige fra hverandre på grunn av et koherens-mål. Koherensen mellom basiskanalene (f.eks. den venstre og den venstre surround, rekonstruerte kanal) reduseres ved å beregne (322) en basiskanal for en av disse kanalene ved en kombinasjon av inngangskanalene, der denne kombinasjonen bestemmes av koherens-målet. Således kan en høy subjektiv kvalitet for rekonstruksjonen tilveiebringes på grunn av en tilnærming av en opprinnelig fremre/bakre koherens.
