Elastique TimeStretch is a high-quality algorithm for changing audio duration (time-stretch) and pitch independently. It preserves audio quality, minimizes artifacts (phasiness, transient smearing) and is widely used in DAWs, plugins, and real-time audio tools. There are several elastique variants (e.g., elastique Pro, elastique 3, elastique 3 Pro) optimized for different use-cases (transients, tonal material, solo/mono, multitrack).
The name "elastique" comes from the French word for elastic, perfectly describing what the algorithm does: it stretches or compresses audio in time without permanently altering its pitch, or shifts pitch without changing duration. elastique timestretch
élastique Pro: The flagship general-purpose engine. It uses advanced psychoacoustic models to ensure sharp transients and crystal-clear vocals, even with extreme stretching. Elastique TimeStretch — Educational Tutorial What it is
