Material for publication

To illustrate actual noise reduction a spectrogram of an unprocessed and its respective processed condition is depicted in the following Figure. In this example a male speech is mixed with babble noise at 7 dB SNR. The upper panel shows the unprocessed condition (Reference) while the subjacent panels display the processed conditions (MS, CBB and AMS) by Harlander et al (2012)***.
