This article investigates how lacking suitable platforms for laboratory exercises becomes a learning problem, limiting the practical experience students gain. In engineering education, laboratory demonstration difficulty of issues like real-time streaming in digital signal and audio processing is highly platform-dependent. Our objective is to propose using our work in open source soundcards (Dimitrov, 2010; Dimitrov and Serafin, 2012, 2011a, 2011b, 2011c), as low-cost platform basis for potential development of innovative laboratory courses. We find that the soundcard implementation study afforded by such laboratories, and their open nature, could testably improve the diversity of demonstrated practical topics, while maintaining engineering students' motivation.
