  abstract={In this contribution a new noise reduction scheme for multi-microphone speech enhancement, called Adaptive Post-filter Extension for Superdirective beamformers (APES), will be introduced, The combination of the superdirective beamformer and the adaptive post-filter has a great potential to suppress diffuse noise. It also outperforms all related algorithms in terms of noise reduction, without increasing signal cancellation. Additionally, a new and easy-to-implement estimator of the post-filter transfer function will be given.},
