Our friends at Sound Radix are offering their plug-in Pi, a Phase Interaction Mixer to minimize frequency cancellations in the DAW summing process, at 60% off for just $99 from today until March 28th 2015.

Here’s what they say about it:

Pi is an innovative, multi-channel phase interactions mixer plug-in engine for Mac and PC that works to improve the summing of a DAW or a mixer. Pi dynamically minimizes frequency cancellations between instruments within the mix, improves mono compatibility and brings back the lost depth and focus lost when overlapping frequencies collide.

Go offer to the Sound Radix store and snap up a Pi.
