Abstract

Et inngangsaudiosignal med en innkommende temporal omhylningskurve blir konvertert til et utgående audiosignal med en utgående, temporal omhylningskurve. Den innkommende, temporale omhylningskurve av inngangsaudiosignalet blir karakterisert. Inngangsaudiosignalet blir behandlet for å generere et behandlet audiosignal hvor behandlingen dekorrelerer inngangsaudiosignalet. Det behandlede audiosignal blir justert basert på den karakteriserte, innkommende, temporale omhylningskurve for å generere det utgående audiosignal hvor den utgående, temporale omhylningskurve vesentlig tilsvarer den innkommende, temporale omhylningskurve.
