Synths node
PaulStretch
Stretches any audio file up to 1000 times longer without changing its pitch, turning a two-second vocal snippet into an hours-long, slowly shifting ambient texture. The classic "everything sounds like a choir of angels" trick.
What it does
PaulStretch is a synth: it turns notes into sound. It takes audio in and gives audio out.
Try it
Stretch a spoken-word sample 20x and drown it in reverb for an instant soundscape bed.
