Lecture "Digital Audio Effects"

Basic Information

Lecturers:   Klaus Linhard  (lecture and exercise)
Room:   Builing F, room F-SR-II (in the first week), building F, room F-SR-III (in the second week), and PC lab in building B (in the second week).
Language:   English
Target group:   Students in electrical engineering and computer engineering
Prerequisites:   Previous knowledge about digital signal processing and linear systems. Some experience with MATLAB is useful, but not mandatory.
Contents:  

Students attending this lecture should be able to implement efficient and robust signal processing structures. Knowledge about moving from the analog to the digital domain and vice versa including the involved effects (and trap doors) should be acquired. Also differences (advantages and disadvantages) between time and frequency domain approaches should be learnt.

Philipp is now "Doc Bulling"

On Monday, 10th of September 2018, Philipp Bulling sucessfully defended his dissertation on speech enhancement for in-car communication systems. His work focused mainly on the control of adaptive feedback cancellation filters (details can be found here). After an excellent talk Philipp gave very good answers to the questions of the committee and at around 11:30 h everythings war over and we ...
