Ableton Live's Grain Delay gives us the ability to slice our input signal into tiny particles (called "grains") and then individually delay and re-pitch those particles.
On top of that, Grain Delay allows us to add a bit of randomness to our delay and pitch, which can produce a complex tail like texture that is 100% unique from the original sound.
