Signal Enhancement for the SPID Corpus

In order to cancel the noise introduced by the ambiance simulation, an adaptive filter based noise cancellation algorithm was applied to the recordings of the SPID corpus. Furthermore, a frequency-domain noise and cross-talk suppression was applied. The two time and time-frequency pots below show examples. The enhanced as well as the original signals are available for the entire corpus parts where the ambiance simualtion was used.

Alexej Namenas - A New Guy in the Team

In June Alexej Namenas started in the DSS Team. He will work on real-time tracking algorithms for SONAR applications. Alexej has done both theses (Bachelor and Master) with us. The Bachelor thesis in audio processing (beamforming) and the Master thesis in the medical field (real-time electro- and magnetocardiography). In addition, he has intership erperience in SONAR processing.

We are pretty ...
