following work is the result of my bachelor thesis,
titeled “Real-time implementation of a tube
preamplifier in order to distort discrete audio
signals” (original title in German:
“Echtzeit-Implementierung einer Röhrenvorstufe zur
Verzerrung diskreter Audiosignale”). I wrote the
thesis in cooperation with d&b audiotechnik GmbH in
summer 2012. The unauthorised use, reproduction, or
