Abstract
Un método incluye generar una señal residual de banda alta con base en una porción de banda alta de una señal de audio. El método además comprende generar una señal armónicamente extendida al menos parcialmente con base en una porción de banda baja de la señal de audio. El método además comprende determinar un factor de mezcla con base en la señal residual de banda alta, la señal armónicamente extendida y el ruido modulado. El ruido modulado está basado al menos parcialmente en la señal armónicamente extendida y ruido blanco.
