You can use the dual mono signal quite handily. Put it into your audio
software and use the facility (which most have) of centre channel or
vocal extraction. That way you will lose the spitches (which are 99%
left or right, but never centre),

Also if you need to do any real repairs to remove a pop, you can
select the option to copy and paste from one channel to the other.

The click energy can be mostly in the L, R, difference or sum channels
depending on how the damage was done. In the case of a click that is mainly
L or R then a copy & paste from the "good" channel to the "bad" can be very
effective, when the click energy is mainly difference averaging the signal
can largely eliminate it. But there are a hard core (far more than 1%) of
cases when none of those work, and we are back to removing the click the
hard way.

Then save it as pure mono, and it will halve the file size.

And will remove a lot (though nothing like 99%) of the surface crackle and
much of the distortion.
