Abstract

In this contribution a new software environment for an embedded system is presented that is part of a laboratory for teaching students in Digital Audio Signal Processing. This environment enables even students with only a limited background in programming embedded technology to achieve remarkable implementations of real-time projects including runtime user interaction. Hardware and algorithm related programming issues are separated for audio processing and interactive messaging. While the hardware related part is provided along with the software environment the students can completely focus on algorithmic aspects. A well defined interface builds the bridge between the two programming components. Examples are presented to demonstrate the flexibility and efficiency of the given software platform. The underlying projects were defined, implemented and finally demonstrated by students in an interactive real-time demonstration.
