Abstract
Los datos de audio recibidos pueden incluir un primer conjunto de coeficientes de frecuencia y un segundo conjunto de coeficientes de frecuencia. Los parámetros espaciales para -al menos- parte del segundo conjunto de coeficientes de frecuencia se pueden estimar, sobre la base -al menos en parte- del primer conjunto de coeficientes de frecuencia. Los parámetros espaciales estimados se pueden aplicar al segundo conjunto de coeficientes de frecuencia, para generar un segundo conjunto de coeficientes de frecuencia modificado. El primer conjunto de coeficientes de frecuencia puede corresponder a un primer rango de frecuencias (por ejemplo, un rango de frecuencias de canal individual) y el segundo conjunto de coeficientes de frecuencia puede corresponder a un segundo rango de frecuencias (por ejemplo, un rango de frecuencias de canal acoplado). Los coeficientes de frecuencia combinados de un canal de acoplamiento compuesto pueden estar basados en coeficientes de frecuencia de dos o más canales. Se pueden calcular los coeficientes de correlación cruzada, entre los coeficientes de frecuencia de un primer canal y los coeficientes de frecuencia combinados.
