(Past) Thematic seminar on localization, separation and tracking of audio sources

In the context of IRISA D5 (Signal, Image & Robotics) department’s scientific seminars, we held a thematic seminar on localization, separation and tracking of audio sources, on February, 19th and 20th 2013.

Audio source separation consists in extracting individual contributions of different audio sources (speakers, musical instruments…) to a mixture. It is now mature enough to envision applicative transfer. Related research issues are not all solved yet, especially in real-world context : reverberant environments, diffuse or moving sources… Source separation is deeply related to the problems of locating and tracking sources, which are generally a front-end to source separation systems.

This two-day workshop aimed at giving a tutorial overview of source localization and separation scientific background, as well as advanced presentations on some recent approaches to these problems in different contexts.

The seminar was open to academic and industrial experts, as well as Ph.D candidates, postdoctorate researchers and colleagues from neighboring research fields who wish to learn the basics of source separation, or improve their knowledge of the domain and of its current theoretical and practical challenges. The program is labeled « complément scientifique » by Ecole Doctorale Matisse.
