Not this time.
I made a seemingly facetious comment early on in this thread
but I was being serious. Isn’t it the case that the Western scale system is not totally mathmatically accurate? When I tune my guitar (currently a Gibson Les Paul Standard, but applies to all the guitars I’ve ever owned) it’s actually impossible to get it “in tune” with itself, because the fret placing is an approximation. If it works for one string it won’t work work for the others.
A vocalist that is pitch perfect is a boring vocalist. A musician that doesn’t use vibrato and slides, is a boring musician.
With all the processing crap that audio goes through from the original to what comes out of a listeners’ speakers, a 10 or even 20 cent variance is not going to be audible.
VariAudio may be inaccurate, and you may be able to hear it in isolation, but in a mix? There are other, more pressing issues to worry about.
Edited because I missed out the word “won’t”. Doh!
