  It is a sort of experiment.  Suppose you have a
multi channel audio file,
 i.e.  composed by, say, three, or four different channels.  Is it possibile
 (I guess it is), and how?, to send each of the four channels into a different
 loudspeaker and so listen to the song...?  Do you think, e.g., the Behringer
 UMC404HD audio interface will allow to do that? 
 Thanks to Jeanette and Fons for their help.  Now please one more
 question: I've
 got two such 3.5mm jack stereo microphones:

 Yes, I know, it's cheap and maybe not very high quality, but it suits well to
 my needs of simple home made recordings.  Do you think it's suppported by the
 Behringer UMC404HD?  With a proper adapter, is it possible to live
 record using
 that microphone and that audio interface? 
 You'd need 4 Phantom-Power to Plugin-Power adapters, like the
 Røde VXLR+.  That would be sort of defeating the "cheap" aspect.  You
 are probably better off getting something like a Zoom H2n recorder and
 use that for creating a four-track recording.
