P10-1 Audio DSP from Scratch for Students of Computing—Ewa Lukasik, Poznan University of Technology - Poznan, Poland
The paper presents a set of dedicated programming applications for teaching digital audio basics to the novices with the background in computing. These applications have been used in the Institute of Computing Science Poznan University of Technology for over 15 years. Each application is devoted to an individual subject, is self explanatory, illustrates the given topic, and includes several simple problems to be solved by students. The topics include: the idea of signal energy and RMS, signals orthogonality, signals approximations, simple sinusoidal synthesis, spectrum, sampling theorem, upsampling and downsampling, convolution, idea of digital filters and interpretation of frequency characteristics, FIR and IIR filters—their zeroes and poles, windowing, DFT and its time and frequency resolution, cepstral analysis, and others. This set of programs proved useful as a starting point to more advanced audio projects in the domain of MIR, speech and speaker recognition, speech synthesis, audio coding, audio transmission, and others.

P10-2 A Comparison of Audio Frameworks for Teaching, Research, and Development—Martin Robinson, University of the West of Engand - Bristol, UK; Jamie Bullock, Birmingham Conservatoire - Birmingham, UK
This paper compares a range of audio frameworks for the support of teaching, research, and the development of audio applications. The authors employ a range of metrics with which to compare the frameworks including: licensing terms, portability across different architectures, audio data-type support, efficiency of processing code, expressiveness, usability, and community activity. Conclusions are drawn that none of these frameworks score highly in all of these domains. This suggests that while there are already a large number of such frameworks there remain areas to be addressed. The authors suggest that this might be through the development of existing systems or the development of new frameworks to meet these needs.
