We propose to repeat the [http://sisec2010.wiki.irisa.fr/tiki-index.php?page=Underdetermined-+speech+and+music+mixtures|underdetermined-speech and music mixtures] task in SiSEC2010 with fresh test data.

* __simulated recordings__ (static sources filtered by impulse responses recorded in a real room situation with loudspeakers and omnidirectional microphones)
- The room dimension for simulated recordings was 4.45 x 3.55 x 2.5 m, and the distances between the sources and the center of the microphone pair was 1.0 m. The reverberation time for simulated recordings was set to either 130 ms or 380 ms and the distance between the two microphones to either 5 cm or 50 cm. Therefore, 5 mixing conditions are considered, together with instantaneous mixtures.

For each mixing condition, 2 mixture signals have been generated from different sets of source signals placed at different spatial positions: @@ -Lignes: 75-79 changées en +Lignes: 78-82 @@

All mixture signals and source image signals have 10s duration. Music source signals have 11s duration to avoid border effects within convolutive mixtures. The last 10s are then selected once the mixing system has been applied.
