Abstract
La descripción se relaciona con métodos de procesamiento de una señal de audio espacial para generar una representación comprimida de la señal de audio espacial. Los métodos incluyen analizar la señal de audio espacial para determinar las direcciones de arribo para uno o más de los elementos de audio; para al menos una subbanda de frecuencia, determinar las indicaciones respectivas de la potencia de señal asociada con las direcciones de arribo; generar metadatos que incluyen información de dirección que incluyen indicaciones de las direcciones de arribo de los elementos de audio e información de energía que incluye indicaciones respectivas de la potencia de señal; generar una señal de audio basada en canales con un número predefinido de canales sobre la base de la señal de audio espacial; y enviar, como la representación comprimida, la señal de audio basada en canales y los metadatos. La descripción se relaciona además con métodos de procesamiento de una representación comprimida de una señal de audio espacial para generar una representación reconstruida de la señal de audio espacial y un aparato, programas y medios de almacenamiento correspondientes.
