R help - Oct 2011 - Independent component analysis with only one "source" of data

Hi,

Looking at the fastICA library.  I want to test separating out different sounds
from a recorded wav file.

But, I only have a SINGLE stream of data (one channel wav.)  It appears as if
the fastICA won't let me separate more sounds than I have columns in my data
matrix.  is this correct?  If so, is there a work around that is commonly used?

Thanks.

No. You cannot get more independent signals as output than you have 
given as input.
