Dear SiSEC2010 participants and organizers,


I'd like to announce that the following changes have been done concerning
"Underdetermined-speech and music mixtures" task:
http://sisec.wiki.irisa.fr/tiki-index.php?page=Underdetermined-+speech+and+music+mixtures (external link)


----------------
I'd like to announce that we've modified following files

- test.zip
test_nodrums_synthconv_250ms_1m_mix.wav
test_nodrums_synthconv_250ms_5cm_mix.wav

- dev1.zip
dev1_wdrums_synthconv_250ms_1m_*.wav
dev1_wdrums_synthconv_250ms_5cm_*.wav

- dev2.zip
dev2_male4_synthconv_250ms_1m_*.wav
dev2_male4_synthconv_250ms_5cm_*.wav

The modification is the DC component removal from their source signals,
and accordingly, the DC removal from all _sim and _mix files.

!!! If you have already started preparing your submissions, !!!
!!! please download again these files, especially "test.zip". !!!


This modification is done because we found that these files of
original version have very large DC components. The other files are
kept as they are, because the other files do not have very large DC
components (not zero, though..).


We would like to thank potential participants for understanding
this modification.

Best regards,
shoko
