It was our pleasure to welcome Prof. Hanseok Ko from the Korea University in Seoul in our Institute. Previously, he reported on "Overview of Deep Learning Based on acoustic signal processing research activities at Korea University" during his visit of the Institute of Technical Acoustics.
As every year, the institute organized the Colloquium Communications Technology on Friday of the last semester week.
Moderated by Thomas Schlien, a number of diverse presentations by IKS-members and the guest speaker Dr.-Ing. Laurent Schmalen have been offered to the participants. These presentations have been followed by numerous demonstrations of current research and student projects.
Together with the physics student and tour guide from RWTHextern at the RWTH Aachen Felix Engelhardt and the science journalist Dipl.-Ing. Jean Pütz took an information tour on the RWTH campus. Among other things, he visited our Institute. We reported on current research activities in the field of speech and audio signal processing. Mr. Pütz particularly liked the fact that many results were demonstrated in terms of prototypes. The research associates of the Institute were pleasantly surprised about the special interest and the many questions of the visitors.
After finishing the recordings with four artificial heads and the corresponding GoPro HERO4 cameras in June, one of the next workpackages was to identify sound passages for demonstration purposes and to cut and edit the different audio and video tracks. Our research assistants Maximilian Kentgens and Stefan Kühl were professionally supported by Justus Thorau, the conductor from the Aachen Symphony Orchestra.
In early July we had the opportunity to record Gustav Mahler's 9th Symphony in the Eurogress. The bright, uniform illumination of the performance area and the proper positioning of the recording unit have led to particularly good results in this extraordinary performance. This recording profited definitely from all our experience gained out of previous measurement campaigns in the orchestra.
From June 29th to 30th 2017 Prof. Dr.-Ing. Peter Vary presented a compact course for development engineers in the area of signal processing and communication technology at Rohde & Schwarz in Munich. The course comprises the theoretical basics of digital modulation and spreading.
During the last six months the IKS performed various sound recordings in the "middle of" the Aachen Symphony Orchestra.
The scientific staff of the IKS held a two-day strategic seminar in the Eifel region to discuss the future orientation and development of the Institute. In addition to new research topics, e.g., in the field of "Spatial Audio Recording and Reproduction", new topics for the lectures were discussed.
