Digital systems have made our lives a lot easier, but they behave in subtly different ways to the analog mental model that most of us have. Some theory helps us to interpret the sonic consequences of technical parameters, inform our handling of digital systems, and successfully navigate marketing language and promises. (English)

Digitale System haben unser Leben sehr vereinfacht, aber sie verhalten sich in vielen Details anders als unsere intuitive Vorstellung, die meist analog geprägt ist. Theoretisches Verständnis hilft uns, die klanglichen Auswirkungen technischer Daten zu interpretieren, unseren Umgang mit Digitalsystemen zu verbessern sowie die Aussagen und Verspechungen von Herstellern einzuschätzen.
