I am working on overlaying other instruments to organya songs, and finding the right tempo is a constant nuisance, because BPM is a direct function with f(x) being speed and x being BPM, while Pixel's WAI(t) units is an inverse function where f(x) is speed and x being WAI.
Since inverse functions are non-linear and direct functions are linear, I am assuming a quadratic equation is necessary for conversion.
I am on my phone ATM, so if someone could give me some WAI values and their exact correlating BPM values (three or four should suffice, they should relatively far apart), I could easily find a formula for converting the two.
Unless such a formula exists.
