i forgot to add that in a stereo recording both l and R channels also have
a difference in amplitude in addition to phase. The Phase and amplitude
difference help the listener to perceive spatial information in the case of
asymmetrically located sources like the background instruments.

From the physics point of view, in a stereo recording, *generally* the
audio has the same phase in both channels whereas the other sounds are
spatially distributed so each will *generally* have different phases in
the L and R channels respectively.
I have based my arguments on my experience with a hardware solution to the
same problem. Maybe you can try finding the arithmetic difference between
the two channels, scale up the result a little a little and listen to the
tracks. If you find the vocal audio missing then you know you are on the
right track. Let me warn you that what i am telling you is some educated
guess work. Please let me know if my suggestion works and then maybe we can
take this further.
I request other members also to comment on this.

Respected all,
I guess this is not the right place to discuss about my problems however
I am sending this mail for at-least some suggestions.
I was trying to work with audio files using python. I need to keep vocals
of an audio file removing the background sounds. I am stuck with the
problem. Can anyone suggest how to proceed?
