In the late 1990s, the digital music world faced a major technical hurdle: "chipmunking." When you sped up a recording, the pitch went up; when you slowed it down, it sounded like a deep, sluggish mumble. A German company called changed this by introducing élastique , a revolutionary time-stretching and pitch-shifting algorithm that decoupled the two. The Core Technology

Pro Tip:

Formant Preservation:

This is the holy grail for vocals. élastique can shift the pitch of a voice while keeping the "formants" (the resonance of the throat and mouth) the same, making a transposed vocal sound like a real human rather than a digital artifact. The Different Flavors of élastique zplane
