Abstract
La presente divulgación proporciona métodos, dispositivos y productos de programas informáticos para la cuantificación no uniforme de parámetros relacionados con la codificación espacial paramétrica de señales de audio. La divulgación se refiere además a un método y un aparato para la reconstrucción de un objeto de audio en un sistema de decodificación de audio teniendo en cuenta los parámetros cuantificados de manera no uniforme. De acuerdo con la divulgación, dicho enfoque hace posible reducir el consumo de bits sin reducir sustancialmente la calidad del objeto de audio reconstruido.
