Therefore a major task is the transmission of stereo speech signals from a noisy environment. The suppression of the noise components must not corrupt the stereo effect. In this context different single channel, multi-channel and hybrid speech enhancement systems will be evaluated in this contribution. The problem of musical noise in Post-Filter-algorithms is addressed. Therefore a psychoacoustic masking threshold for the noise reduction algorithms is considered.}, booktitle={Audio Engineering Society (AES), 120th Convention} }
