Vocal Cut
It is the function which attenuate a vocal from the music source.
The vocal is usually located in the center. And it is same amplitude and phase in L and R channel.
So, a vocal inside music is attenuated by doing L-R. But, a low frequency signal be attenuated in this case.
Therefore, a low frequency signal be made to pass with LPF, and it makes up for the shortage of the low frequency
signal .
(Note), The output of the vocal cut is mono.
