In this week's Friday Free Plug-in, we are featuring Pitchproof from Agean Music, a realtime harmoniser/pitch shifter plug-in.

What Is Pitchproof?

Pitchproof is a very straightforward diatonic pitchshifter which offers pitch shifts of an octave in either direction. With a mix and a detune control this harmoniser can be used for generating harmonies or for thickening effects.

How Do I Get This Plug-in?

Go to the Agean Music website and download it from the list of freeware.

Pitchproof is a free plug-in and no iLok is required to run it. It is available for Mac or PC in VST, AU and AAX plug-in formats.
