Lecture "Digital Audio Effects"

Basic Information

Lecturers:   Klaus Linhard  (lecture and exercise)
Room:   Building F, room F-SR-III
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.

Topic overview:

  • Digital signal processing - summary
    • Ordered sequences of numbers
    • 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

TensorFlow and Escape Rooms

The last two days (Monday and Tuesday, September 16 and 17, 2019), the whole DSS team did a course on TensorFlow and Keras. Since we already have interfaces of TensorFlow to our real-time tool KiRAT, it was time now to extend our knowledge on graphs and the corresponding training of weights, biases, etc. After two days of hard work we booked two escape rooms and solved the "secrets" hidden in ...
