Abstract

Un método de codificación de audio de entrada basado en canal u objeto para reproducción, el método que incluye los pasos de: (a) reproducir inicialmente el audio de entrada basado en canal u objeto en una representación de salida inicial; (b) determinar una estimación del componente de audio dominante del audio de entrada basado en canal u objeto y determinar una serie de factores de ponderación de componente de audio dominante para mapear la presentación de salida inicial en el componente de audio dominante; (c) determinar una estimación de la dirección o posición de componente de audio dominante; y (d) codificar la presentación de salida inicial, los factores de ponderación de componente de audio dominante, la dirección o posición de componente de audio dominante como la señal codificada para reproducción.
