Abstract

See full text

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.
