Ground Breaking Multimedia Enhances DSP Education through Connexions

Professor Ed Doering of Rose-Hulman Institute of Technology presents a Connexions multimedia tour of musical synthesis and signal processing using LabVIEW.


Professor Doering knows that music and sound provide a powerful vehicle for his engineering students to connect classroom signal processing theory with their everyday experiences. In his course "Musical Signal Processing with LabVIEW -- Programming Techniques for Audio Signal Processing", he guides students through hands-on exercises that lead from audio signal theory to signal processing concepts and finally to hardware implementation of musical synthesis algorithms. To do so, he has developed an innovative approach, making use of a programming environment that eases the transition from equations to desktop speakers and delivering his course as a groundbreaking multimedia experience in Connexions.

Professor Doering uses National Instruments graphical programming environment, LabVIEW, to quickly transition from algorithms to implementation and interface those algorithms with the PC sound card. In his Connexions course, he first introduces students to LabVIEW with programming basics and then exposes them to audio and signal processing implementation tactics for music synthesis. His course culminates with the creation of a LabVIEW based music synthesizer for real-time audio output.

The modular nature of Connexions allows Professor Doering to present this material in a natural progression from basic to more audio-specific topics. He pushes the boundaries of Connexions even further, crafting a truly novel multimedia course. In addition to the traditional text-and-image presentation, he also includes over 100 “screencasts,” instructional videos that complete the learning experience. These screencasts combine whiteboard presentation, LabVIEW implementation, and instructor narration to deliver an engaging presentation with many of the aspects of a traditional classroom and laboratory environment.

We encourage Connexions users interested in innovative teaching approaches, music, signal processing and/or LabVIEW to explore this exciting offering, and we look forward to Prof. Doering's next innovative contribution to Connexions!
