Day 4 - Sunday, April/15 
10:30 Minivosc - a minimal virtual oscillator driver for ALSA (Advanced Linux Sound Architecture) - Paper Presentation

(45 min) Smilen Dimitrov, Stefania Serafin » Location: CCRMA Stage
Understanding the construction and implementation of sound cards (as examples of digital audio hardware) can be a demanding task, requiring insight into both hardware and software issues. An important step towards this goal, is the understanding of audio drivers and how they fit in the flow of execution of software instructions of the entire operating system. The contribution of this project is in providing sample open-source code, and an online tutorial [1] for a mono, capture-only, audio driver which is completely virtual; and as such, does not require any soundcard hardware. Thus, it may represent the simplest form of an audio driver under ALSA, available for introductory study; which can hopefully assist with a gradual, systematic understanding of ALSA drivers' architecture and audio drivers in general.

Day 4 - Sunday, April/15 
10:30 Live CSound - Workshop
(90 min) Joachim Heintz » Location: workshop space
This workshop will demonstrate the use of Csound for live situations in PD and CsoundQt. It will show features from my paper (Thursday) in more detail, as well as discussing problems and helping the participants to get things to run.

Day 4 - Sunday, April/15 
11:15 An Open Source C++ Framework for Multithreaded Realtime Multichannel Audio Applications - Paper Presentation

(45 min) Matthias Geier, Torben Hohn, Sascha Spors » Location: CCRMA Stage
An open source C++ framework is introduced which facilitates the implementation of multithreaded realtime audio applications, especially ones with many input and output channels. Block-based audio processing is used. The framework is platform-independent and different low-level audio backends can be used for both realtime and non-realtime operation. Support for further backends can be added easily.

Day 4 - Sunday, April/15 
12pm Using the beagleboard as hardware to process sound - Paper Presentation
author image
(45 min) Rafael Vega González, Daniel Gómez » Location: CCRMA Stage
This paper describes the implementation of diverse layers of code to enable an open source embedded hardware device to run audio processing pure data patches. The evolution of this implementation is reviewed describing different approaches taken by the authors in order to find optimal software and hardware settings. Although some problems are detected when running specific patches, the system has a conjunction of features that are relevant for the floss audio community.
