I just feel like, for just stretching stuff and staying in pitch, any off-the-shelf FFT-based method has near perfect results within a meaningful range anyway. It has felt like a solved problem for a while? What does the "high-quality" mean here?

Most stretching algorithms I've heard have noticeable "ghosting" of transients, and tend to muddle synthesizer tones (due to discarding phase information). I am very curious to test this one.
