Abstract:
Example audio signal processing apparatuses and methods for processing an input audio signal into an output audio signal are disclosed. An example audio signal processing apparatus comprises a decomposer configured to decompose the input audio signal into a direct audio signal and a diffuse audio signal, a modifier configured to modify the direct audio signal in order to obtain a modified direct audio signal, wherein the modifier comprises a bandwidth extender configured to extend an upper cutoff frequency of a frequency range of the direct audio signal, and a combiner configured to combine the modified direct audio signal with the diffuse audio signal to obtain the output audio signal.

Claim (Index 19):
The audio signal processing apparatus of  claim 15 , wherein the programming instructions further instruct the at least one processor to extract a plurality of direct audio signal components from the direct audio signal using a plurality of bandpass filters, wherein each direct audio signal component is associated with a corresponding frequency band of a plurality of frequency bands defined by the plurality of bandpass filters, and wherein the programming instructions further instruct the at least one processor to estimate, for each frequency band of the plurality of frequency bands, the energy of the direct audio signal component associated with the corresponding frequency band.
