1. A process for the control of crystal formation comprising applying ultrasound or acoustics at a level below that which causes cavitation, including stable cavitation and transient cavitation, to a metastable liquid to thereby control energy, mass balance, or both between particles and a liquid phase in the metastable liquid.
