Abstract: A method for processing an audio signal, the method including: processing the audio signal according to a pair of mouth to ear transfer functions to obtain a processed audio signal; filtering the processed audio signal, using a pair of equalization filters, to obtain a filtered audio signal, where a parameter of the equalization filter is depends on an acoustic impedance of a headphone; and outputting the filtered audio signal to the headphone. Accordingly, this method counteracts the occlusion effect and to provides a natural perceived sound pressure.

Abstract: The invention relates to the technical fields of binaural audio rendering and, to this end, estimation of room acoustic parameters like reverberation time. In particular, the invention provides a device and method for estimating such acoustic parameters. The device is configured to record an acoustic signal, particularly a speech signal, to estimate a frequency-dependent reverberation time in a lower frequency range based on the recorded acoustic signal, and to extend the frequency-dependent reverberation time to a higher frequency range based on a predetermined model to obtain an extended frequency-dependent reverberation time. Virtual 3D audio can thus be adapted to a real room.

Abstract: The present disclosure provides a method for evaluating an electronic device. The method comprises determining, with an acoustic tube, a value of a first parameter, the value of the first parameter being indicative of the acoustic impedance of a reference termination. The method further comprises determining, with the acoustic tube, a value of a second parameter, the value of the second parameter being indicative of the acoustic impedance of the reference termination, when occluded by the electronic device. The method then comprises calculating a value of a third parameter, the value of the third parameter being indicative of the acoustic impedance of the electronic device, based on the value of the first parameter and the value of the second parameter.

Abstract: The disclosure relates to a method for processing a stereo signal. The method can include obtaining a center channel signal by up-mixing the stereo signal. The method can also include generating a filtered center channel signal by applying one or more peak filters and one or more notch filters to the center channel signal. Furthermore, the method can include generating a binaural signal based on the filtered center channel signal.
