	abstract = {The goal of the proposed master thesis is to define an architecture that enables visual prototyping of real-time audio applications and plug-ins. Visual prototyping means that a developer can build a working application, including user interface and processing core, just by assembling elements together and changing their properties in a visual way. Specifically, this research will address the problem of having to bind interactive user interface to a real-time processing core, when both are defined dynamically, the set of components is extensible, it allows bidirectional communication of arbitrary types of data between the interface and the processing core, and, it still fulfils the real-time requirements of audio applications.

	abstract = {This article describes a set of patterns the authors have seen emerging during years of experience developing assorted applications in the sound and music domain and receiving influences from theoretical models, existing systems, and colleagues. 
Those patterns aim at offering a generative pattern language that falls within a generic data flow architecture. Regardless the audio domain origins of the patterns, we foresee that they have applicability in other domains. Contributions of this paper are General Data-flow Patterns, that address problems about how to organize high-level aspects of the data-flow architecture, by having different types of modules connections; Flow Implementation Patterns, that address how to physically transfer tokens from one module to another, according to the types of flow defined by the "general data-flow patterns''. Tokens life-cycle, ownership and memory management are recurrent issues in those patterns; and finally, Network Usability Patterns, that address how humans can interact with data-flow networks.}, URL = {files/publications/2ddcef-PLOP-2006-arumi-garcia-amatriain.pdf} } @inproceedings { amatriain_ACMMMCLAMFramework, author = {Amatriain, X. and Arumí, P. and Garcia, D.}, title = {CLAM A Framework for Efficient and Rapid Development of Cross-platform Audio Applications}, year = {2006}, abstract = {CLAM is a C++ framework that offers a complete development and research platform for the audio and music domain. Apart from offering an abstract model for audio systems, it also includes a repository of processing algorithms and data types as well as a number of tools such as audio or MIDI input/output. All these features can be exploited to build cross-platform applications or to build rapid prototypes to test signal and media processing algorithms and systems. The framework also includes a number of stand-alone applications that can be used for tasks such as audio analysis/synthesis, plug-in development or metadata annotation.

Formatting task has been distributed along the system objects in a compositional way, making easy to format a single object from its parts. The system minimizes the overhead added to a class and the programmer effort to support XML I/O. A default XML implementation has been provided for most of the future data structures, giving the chance to customize it.
