My basic problem is that I'm really struggling to hear the difference between many of your samples :-) And I've already got a bit of experience with microtonality (DSP background, playing and have tuned multiple instruments, reasonable pitch perception). One of the big problems for me is that it's not so easy to hear them side-by-side; you have to stop one of them, then start the other (unless you want them both at the same time, which you probably don't), and both the start and stop buttons are pretty laggy. FWIW, most audio comparison tools I've seen (typically centered around compression or restoration) include some way of switching seamlessly between the two, without restarts.
