Kurzfassung: |
The transfer function in the look-direction is an adaptive Wiener-Filter which is estimated by using the short-time Fourier transform and the Nuttall/Carter method for spectrum estimation. The experimental results demonstrate that the proposed method works well for a large range of reverberation times and is therefore able to operate independently of the correlation properties of the noise field. |
