Abstract
Webcasting and recording of university lectures has become common practice. While much effort has been put into the development and improvement of formats and codecs, few scientist have studied how to improve the quality of the signal before it is digitized. Lecture halls or seminar rooms are not professional recording studios. Good quality recordings require full-time technicians to setup and monitor the signals. This paper describes a tool that eases studioless voice recording by automatizing several tasks usually handled by audio technicians. The expert system measures the quality of the sound hardware used, monitors possible hardware malfunctions, prevents common user mistakes, and provides gain control and filter mechanisms.
