Abstract
Un aparato que comprende medios para obtener, con respecto a al menos dos fuentes dentro de una escena de audio, parámetros de metadatos direccionales ordenados, en donde los parámetros de metadatos direccionales ordenados están asociados con las al menos dos fuentes, en donde los parámetros de metadatos direccionales identifican una dirección de llegada con respecto a las al menos dos fuentes y están dispuestos en tramas organizadas como una cuadrícula de bloques de tiempo-frecuencia con respecto a un eje de tiempo y un eje de frecuencia; determinar un error de ordenamiento con respecto al al menos un parámetro de metadatos direccionales de un bloque de tiempo-frecuencia, en donde el error de ordenamiento está configurado para identificar que el al menos un parámetro de metadatos direccionales de un bloque de tiempo-frecuencia vecino asociado con otro índice de orden es más similar y/o menos diferente con respecto al al menos un parámetro de metadatos direccionales de un bloque de tiempo-frecuencia que el al menos un parámetro de metadatos direccionales de un bloque de tiempofrecuencia vecino asociado con el mismo índice de orden; y reordenar el al menos un parámetro de metadatos direccionales de un bloque de tiempo-frecuencia determinado al otro índice de orden.
