Abstract
En general, se describen técnicas para compresión y decodificación de datos de audio; un ejemplo de un dispositivo para comprimir datos de audio incluye uno o más procesadores configurados para aplicar una transformada de descorrelación a coeficientes ambisónicos ambientales para obtener una representación descorrelacionada de los coeficientes ambisónicos ambientales, los coeficientes HOA ambientales habiendo sido extraídos de una pluralidad de coeficientes ambisónicos de orden superior y representativos de un componente de segundo plano de un campo de sonido descrito por la pluralidad de coeficientes ambisónicos de orden superior, en donde al menos uno de la pluralidad de coeficientes ambisónicos de orden superior está asociado con una función base esférica que tiene un orden mayor que uno.
