Title: APPARATUS AND METHODS FOR PROCESSING AN AUDIO SIGNAL
Abstract:
An apparatus for processing an audio signal comprises a separator for separating a first portion of a spectrum of the audio signal from a second portion of the spectrum of the audio signal, the first portion having a first signal characteristic and the second portion having a second signal characteristic. The apparatus comprises a first bandwidth extender for extending a bandwidth of the first portion using first parameters associated with the first signal characteristic, for obtaining a first extended portion and comprises a second bandwidth extender for extending a bandwidth of the second portion using second parameters associated with the second signal characteristic, for obtaining a second extended portion. The apparatus comprises a combiner configured for using the first extended portion and the second extended portion for obtaining an extended combined audio signal.
