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 13):
The audio signal processing apparatus of  claim 12 , wherein the reverberation adjuster is configured to adjust the direct audio signal filtered by the reverberation filter based on the third adjustment factor, wherein the ratio between the energy of the modified direct audio signal and the diffuse audio signal of the output audio signal is larger than a predefined fraction of the ratio between the energy of the diffuse audio signal and the direct audio signal provided by the decomposer.
