Talk to me about this not doing the whole file and just the selected to end?
Also, either way, remember to highlight just from the point of alignment in the beginning not the whole file.
I just realized I haven't been doing it as accurately as possible. I haven't been removing the time prior to the point of alignment from the equation.
What should be measured is the total samples (or seconds as I do it) just from the beginning point of alignment to where they should meet up in the end. Since the percentage difference you get at the end is just the percent you need to change for that specific area, if you changed the speed of more than just that area, it would end up off. (I'm not good at this, someone else can probably explain it better if that doesn't make sense)
In other words I guess; If your original point of alignment for both tracks is at :10 (seconds) and the point of alignment you want at the end is say 1:00 (minute) and on the second track that same point is at 1:01. Your calculations should only be measured from :10 (beginning alignment) to 1:00 and 1:01 (points you want to align at the end), since technically before and after those two points will be off after this. Divide the larger number (sample) by the smaller whatever to find the percentage difference of just the area
from the original alignment (:10) to 1:00. That means if you changed the speed of anything more (or less) than that specific area (ie highlight the whole file), the percent speed change would be different and therefore the tracks would be slightly off.
Does that make sense?
