Fundamental signal theory is the basis for everything that we do. It helps us sort and categorize our daily listening experiences, and to form a practical understanding of the tools we use (and how to use them even better), but also to recognize their limitations. (English)

Signaltheorie ist die Grundlage unseres Handelns. Sie hilft uns, unsere täglichen Arbeits- und Hörerfahrungen einzuordnen, ein praktisches Verständnis unserer Werkzeuge zu entwickeln, sie noch besser zu nutzen, aber auch, ihre Grenzen zu erkennen. (German)
