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.

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.

In addition, each participant is asked to provide basic information about his/her algorithm (e.g. a bibliographical reference) and to declare its average running time, expressed in seconds per test excerpt and per GHz of CPU.
- "How to submit" will be announced by July, 2011.
+ !!!How to submit
Each participant should make his results available online in the form of a tarball called <YourName>_<dataset>.zip. The included files must be named as follows: * <dataset>__<srcset>_<mixtype>_<reverb>_src_<j>.wav: Estimated source <j> for task 2. Mono WAV file sampled at 16 kHz. * <dataset>__<srcset>_<mixtype>_<reverb>_sim_<j>.wav: Estimated spatial image of source <j> for task 3. Stereo (3ch for test3/dev3) WAV file sampled at 16 kHz. <br />* task1.txt: Estimated source numbers for task 1. The file's 1st column is the mixture label (dev1_<srcset>_<mixtype>_<reverb>_<spacing>_mix) and 2nd column is the estimated number of sources. where <dataset> is one of the test/test2/test3/dev2/dev3, <srcset> is a shortcut for the set of source signals, <mixtype> for a shortcut for the mixture type, <reverb> the reverberation time and <spacing> the microphone spacing. Each participant should then send an email to "araki.shoko (at) lab.ntt.co.jp" providing: * contact information (name, affiliation) * basic information about his/her algorithm, including its average running time (in seconds per test excerpt and per GHz of CPU) and a bibliographical reference if possible * the URL of the tarball(s)
