Abstract

Un aparato (100) para generar una pluralidad de transmisiones de audio paramétricas (125) (?i, ?i, Wi) desde una señal espacial de audio de entrada (105) obtenidas desde una grabación en un espacio de grabación comprende un segmentador (110) y un generador (120). El segmentador (110) se configura para proveer al menos dos señales de audio segmentales de entrada (115) (wi, Xi, Yi, Zi) desde la señal espacial de audio de entrada (105), donde las al menos dos señales de audio segmentales de entrada (115) (Wi, Xi, Yi, Zi) se asocian a correspondientes segmentos (Segi) del espacio de grabación. El generador (120) se configura para generar una transmisión de audio paramétrica para las al menos dos señales de audio segmentales de entrada (115) (Wi, Xi., Yi, Zi) para obtener la pluralidad de transmisiones de audio paramétricas (125) (?i, ?i, Wi).
