Abstract

La presente divulgación se relaciona con un método de procesamiento de contenido de audio que incluye la información de directividad para al menos una fuente de sonido, comprendiendo la información de directividad un primer conjunto de vectores unitarios de primera directividad que representan direcciones de directividad y ganancias de primera directividad asociadas. La divulgación además se relaciona con los correspondientes métodos de codificación y decodificación de contenido de audio que incluye la información de directividad para al menos una fuente de sonido.The present disclosure relates to an audio content processing method that includes directivity information for at least one sound source, the directivity information comprising a first set of first directivity unit vectors representing directivity directions and gains. first associated directivity. The disclosure further relates to corresponding methods of encoding and decoding audio content including directivity information for at least one sound source.
