I use it to figure out the correct playback speed for a record - not 
to correct pitch variations within a record. I use the spectrum 
analyzer to get the frequencies of notes in the recording and figure 
out how much it would have to speed up or slow down for each note to 
be on pitch. I then take the average of the speed changes and use 
that to figure out the correct playback speed.

"A vs. B" is a standard phrase meaning "A on one axis of the graph 
and B on the other."

Sorry - I'm not aware of any tool that does this.
