In  this paper we propose a test that allows a comparison of different  ICA and ISA algorithms from this perspective. The test consists in  evaluating separation of a pseudo-convolutive mixture of given  independent signals. The mixture has features of real-world  convolutive mixtures and of instantaneous mixtures simultaneously.  We apply the proposed test to compare performance of several ICA  and ISA algorithms in four different scenarios, taking in mind  that suitability of the algorithms depends on properties of the  separated signals.</abstract> <abstract language="cze" primary="0">Slepá separace konvolutorních směsí zvukových signálů může být prováděna v časové oblasti jak s využitím metod analýzy nezávislých komponent, tak pomocí analýzy nezávislých podprostorů. V práci je navržen způsob porovnání efektivity obou přístupů. Test spočívá ve vyhodnocení výsledků separace pseudo-konvolutorní směsi, která má vyžaduje separaci podprostorů, a přitom teoreticky umožňuje perfektní separaci. Celkem je porovnáno jedenáct různých algoritmů pro separaci čtyř druhů separovaných signálů.</abstract>  <action target="WRD"> <ARLID>cav_un_auth*0254046</ARLID> <name>17th European Signal Processing Conference (EUSIPCO 2009)</name> <place>Glasgow</place> <dates>24.08.2009-28.08.2009</dates>  <country>GB</country> </action>    <reportyear>2010</reportyear>  <RIV>BB</RIV>      <permalink>http://hdl.handle.net/11104/0178018</permalink>        <arlyear>2009</arlyear>       <unknown tag="mrcbU56"> pdf 342 kB </unknown> <unknown tag="mrcbU63"> cav_un_epca*0332899 17th European Signal Processing Conference (EUSIPCO 2009) 1447 1451 Glasgow University of Strathclyde, Glasgow 2009 </unknown> </cas_special> </bibitem>
