Hi Jo,
To some extent, yes, but only if you are working with material
which can tolerate the artefacts that blind source separation
algorithms will, sooner or later - and usually sooner - generate. Such
algorithms, including those in Harpex, are getting much better (I can
remember hearing some really terrible earlier attempts) but, so far
anyway, it is always possible to find some material that will screw
them up. There are two factors which will reduce this as time goes on
- the continuing improvements in the technology and the fact that much
of the audience these days have perceptions that are so screwed up by
listening to compressed audio that maybe the artefacts maybe won't be
heard by them anyway :-)
All the best
Dave
