Abstract

La presente invención se refiere a la representación Ambisonics de orden superior que representa un sonido tridimensional independiente de una configuración específica de altoparlante. Sin embargo, la transmisión de una representación HOA (Higuer Order Ambisonics - representación Ambisonics de orden superior) genera una tasa de bits muy alta. Por lo tanto, se utiliza compresión con un número fijo de canales, en los cuales los componentes de señal direccional y ambiente se procesan de manera diferente. El componente de HOA ambiente es representado por un número mínimo de secuencias de coeficientes de HOA. Los canales restantes contienen señales direccionales o secuencias adicionales de coeficientes del componente de HOA ambiente, dependiendo de la óptima calidad perceptual obtenida. Este proceso puede cambiar trama por trama.
