  1. Verfahren zur räumlichen Synthese eines Summensignals, um mindestens zwei digitale Ausgangs-Audiosignale zu erhalten, wobei das Summensignal sowie Verräumlichungsparameter aus einer parametrischen Codierung durch Matrizierung eines ursprünglichen digitalen Mehrkanal-Audiosignals stammen, wobei das Verfahren die folgenden Schritte aufweist:
    - Dekorrelierung (Decorr.) des Summensignals (s), um ein dekorreliertes Signal (d) zu erhalten;
    - Anwendung (Synth.) einer Synthesematrix (M Minq), deren Koeffizienten von den Verräumlichungsparametern (R, I) abhängen, an das dekorrelierte Signal und an das Summensignal, um die Ausgangssignale zu erhalten,
    dadurch gekennzeichnet, dass für mindestens einen Wertebereich mindestens eines Verräumlichungsparameters die Koeffizienten der Synthesematrix gemäß einem Minimierungskriterium einer quantitativen Funktion (q) bestimmt werden, die sich auf die dekorrelierte Signalmenge in jedem der durch den Anwendungsschritt der Synthesematrix erhaltenen Ausgangssignale bezieht, wobei die quantitative Funktion so ist, dass die Erhöhung des Absolutwerts der an das dekorrelierte Signal angewendeten Koeffizienten der Synthesematrix den Wert der an diese gleichen Koeffizienten angewendeten Funktion erhöht.
  2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die quantitative Funktion eine Energiefunktion des dekorrelierten Signals ist.
  3. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die quantitative Funktion von der Art ist:
    q x y = x p + y p 1 p
    Figure imgb0031
     mit p einer ganzen Zahl größer als oder gleich 1.
  4. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Verräumlichungsparameter ein Parameter (R) des Energieverhältnisses zwischen den Kanälen des Mehrkanalsignals und ein Parameter (I) der Interkanal-Korrelation des Mehrkanalsignals sind, wobei ein Werterbereich der Bereich ist, in dem der Interkanal-Korrelationsparameter negativ ist.
  5. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass eine andere quantitative Funktion pro Wertebereich der Verräumlichungsparameter gewählt wird.
  6. Vorrichtung zum räumlichen Synthese eines Summensignals, die mindestens zwei digitale Ausgangs-Audiosignale erzeugt, wobei das Summensignal sowie Verräumlichungsparameter von einer parametrischen Codiervorrichtung stammen, die eine Matrizierung eines ursprünglichen digitalen Mehrkanal-Audiosignals durchführt, wobei die Vorrichtung aufweist:
    - Dekorreliereinrichtungen (510) des Summensignals, um ein dekorreliertes Signal zu erhalten;
    - Einrichtungen (520) zur Anwendung einer Synthesematrix (M Minq), deren Koeffizienten von den Verräumlichungsparametern abhängen, an das dekorrelierte Signal und an das Summensignal, um die Ausgangssignale zu erhalten,
    dadurch gekennzeichnet, dass für mindestens einen Wertebereich mindestens eines Verräumlichungsparameters die Koeffizienten der Synthesematrix gemäß einem Minimierungskriterium einer quantitativen Funktion bestimmt werden, die sich auf die dekorrelierte Signalmenge in jedem der Ausgangssignale bezieht, die durch die Anwendungseinrichtungen der Synthesematrix erhalten werden, wobei die quantitative Funktion so ist, dass die Erhöhung des Absolutwerts der an das dekorrelierte Signal angewendeten Koeffizienten der Synthesematrix den Wert der an diese gleichen Koeffizienten angewendeten Funktion erhöht.
  7. Decodierer eines digitalen Audiosignals, der mindestens eine Synthesevorrichtung nach Anspruch 6 aufweist.
  8. Multimediaausrüstung, die einen Decodierer nach Anspruch 7 aufweist.
  9. EDV-Programm, das Codeanweisungen für die Durchführung der Schritte des Verfahrens nach einem der Ansprüche 1 bis 5 aufweist, wenn diese Anweisungen von einem Prozessor ausgeführt werden.
