[Ardour-Users] karaoke and voice removal

[I. Ivanov]

Hi All,

Can you please let me know if it is possible to remove the voice from 
recording?

This song is original (with the voice)

This is instrumental version

I am rather new to audio editing and I just want to learn if there is 
some tool that can remove the voice that I am not aware about (I did try 
the "karaoke" plugin in Ardour) or it is not possible - the song must be 
produced without voice (instrumental version only). That would mean the 
second (instrumental) version was likely not the "original" but rather 
re done by somebody else.

I would appreciate your advice...

Regards,

B
