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

Formant Preservation

: In plugins like Elastique Pitch , the engine can shift pitch while keeping the "character" or vocal tract length (formants) natural, avoiding the "chipmunk" effect. Integration in DAWs elastique timestretch
