Still in beta (but seems to work fine), and can be
downloaded now as part of the 11.08 beta pack.

What is a spectral panner? It lets you pan different frequencies independently. This one lets you draw a freeform pan map over a spectral display or sonogram. Use it for widening stereo tracks. I'm guessing there will be a paid version of it later, probably adding modulation.
