xoxos has released Caprice, a VST effect plugin for Windows that will enable you to achieve new creative effects with spectral resynthesis.
Caprice includes several discrete processes that transform your audio into something it wasn't before. Smoothly crossfade from a sound into pure noise. Create an aura of frequencies around a signal that isn't there. Add frequencies below those existing in a voice for monstrous effect. In addition to several creative ways to add frequency content based on what is in your file, Caprice uses a unique frequency shifting algorithm that creates hypnotic cascades instead of normal feedback loops. Your audio will never be the same with Caprice.
