Before technologies like élastique, changing a sample's speed would also change its pitch (like a vinyl record speeding up). This made it difficult to combine samples from different sources. With élastique, audio becomes "elastic"—you can bend, stretch, and pitch it to fit any creative vision without sacrificing the professional sound quality required for radio or streaming.
| Algorithm | Best For | Weakness | | :--- | :--- | :--- | | | Pads, Textures, Ambient | Can sound grainy/phasey on transients | | Phase Vocoder | Smooth stretching, Choirs | Can sound "robotic" or metallic | | Elastique (Hybrid) | Transients, Vocals, Polyphony | CPU intensive (but worth it) | elastique timestretch
For ambient artists, stretching a sound to 400% or 1000% its original length creates lush pads from short sources. While "Paulstretch" is the go-to for extreme timestretching, Elastique offers a cleaner, less noisy result for moderate-to-extreme stretches (up to roughly 300%), making it ideal for cinematic drones. | Algorithm | Best For | Weakness |
