Itsy Audio Phase Inverter

Itsy is a compact dedicated super-spider for managing stereo signals, from flipping left and right channels, to width control and phase inversion. Unlike Reason’s SSL channel Width control, Itsy can reduce both the stereo field to mono, and also invert the channels, giving you flexible width and stereo inversion in one handy, CV-controllable knob.

Itsy features independent left and right channel phase inversion switches and a corresponding correlation (phase) meter for checking the phase of your stereo signal. At +1 both L+R are in-phase, and means you have a mono signal; at -1 the signal is entirely out-of-phase. Stereo signals will typically be between -0.5 and +0.5. The phase controls can be applied to the stereo inverter, or the phase section can be split from the stereo inverter and used on a second signal instead.
