Stereo Audio Source Separation Evaluation Campaign: CALL FOR PARTICIPATION

                *** FIRST CALL FOR PARTICIPATION ***

                 1st Stereo Audio Source Separation
                        Evaluation Campaign


               Participation deadline: April 13, 2007

Do you have an algorithm for source separation from few channels? Or are you interested in this challenging issue? Then you should take part in the first campaign for the evaluation of stereo audio source separation algorithms.

The task is to estimate from a two-channel speech or music mixture the contribution of each source on each channel, the number of sources being equal to three or more. This campaign complements recent evaluation initiatives conducted by Lucas Parra and the PASCAL network, which focused on different numbers of sources and channels.

Three types of mixtures are considered:
- instantaneous mixtures,
- synthetic convolutive mixtures,
- live recordings.

All contributions are welcome, including established, novel, blind or non-blind, two-channel or single-channel algorithms. The evaluation will be non-competitive: the results will be made available on the campaign website for listening and evaluated using multiple criteria, possibly proposed by the participants. The results will be summarized in a paper to be discussed at the ICA'07 conference (see http://www.ica2007.org/), during which the participants who wish to present a poster about their algorithm will also have the opportunity to do so. These posters will then be published on the campaign website.
