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.

    • Difference equations
    • Linear systems
  • Frequency-domain processing - summary
    • Discrete Fourier transform
    • Fast convolution
    • Transfer functions and spectra
  • Introduction to MATLAB and motivation
  • Digital filters
    •  A,B,C,R468 weighting filters
    • Equalizer
    • Sampling rate conversion
  • Dynamic compression

DSS-Retreat 2018

At the end of October (24.10.2018 till 27.10.2018) we spent again a few days on the island Sylt to reflect our past, current, and future research work. This included all Ph.D. topics but also the general direction of our research. Of course, also teaching and team related issues were discussed. Beside all that official work we also enjoyed the time on that beautiful island with several common ...
