Hi:
 
I have two audio tracks that I would like to compare to see if they are identical. To this end, I would like to invert the polarity of one of the tracks and then play both tracks together to hear the result (ie, what I understand to be called the "null test"). If someone would please explain how to invert the polarity of an audio track in Sonar X2, I would appreciate it very much.
 
Thanks.

Phase button is on the Track Inspector top row second button from the left pointed to by "E" in the illustration below from http://www.cakewalk.com/Documentation?product=SONAR%20X2&language=3&help=Inspectors.3.html#1224480

Bare in mind
