Re: Computational ASA
The problem is, indeed, complex. You can learn a bit more about its various
facets if you browse the web site http://www.ebire.org/speechseparation

I know there are several CASA experts on this list, so I'd like to ask why
source separation seems to be so difficult. It's seems like the general
consensus is that source separation is far too difficult, and research has
focused on understanding features within a mix. Yet, from what I've read,
current methods of feature extraction work quite well. It only seems
natural that we could write an algorithm that groups these features
according to their perceived source and creates separate audio streams
based on this information. While this would be much more difficult in
noisy or reverberant environments, I would imagine it would be quite
simple in a less complex environment.
What is it that makes source separation so difficult?
