Hi,
   Im trying to do Independent Component analysis on Mono signal.This
means extracting music or voice or effects from a mono signal which
has a mixture of all these three.It is extracting the source from just
one mixture(mono sound file) .Anybody could help me about how to do
it?

I would need a model using principal component analysis or
indepenedent componetn analysis or anyother method.

ica
Independent Component Analysis 
(V0.04)

INTRODUCTION 

The ica program provides source separation for a number or mixed
signals where the number of recordings is equal to the number of the
sources. A good description of the ICA algorithm used can be
found in [1]. The non-linearity used to perform the separation is
based on either the exp() or tanh() function.

The kernel-ica package is a  Matlab program that implements the Kernel
ICA algorithm for independent component analysis (ICA).

Perhaps Plumbly and Abdulla have devised a way to identify what was
mixed to make a sound track, but I suspect it is very rough, and makes
errors when unususual sounds are put on a sound track. Perhaps an
experience sound mixing person could help the machine make better
guesses.   Neil
