How can resynthesis engines be so accurate despite the time/frequency resolution trade-offs inherent in Fourier analysis?
I'm looking at Harmor specifically, but my question is about resynthesis in general. I assume that Fourier analysis is how these engines break a sound down into its constituent partials with frequency,...
