Flipper
Filed Under: VST Effects/Phase Shifter | report broken link
Flipper is a simple little plug that does an important job. It takes the input signal, in either mono or stereo, and inverts the polarity (a.k.a., “Phase Invert”) just like the “Phase Invert” button found on most larger mixing consoles. If your mono or stereo tracks sound unusually thin it could be because of phase problems. You can flip the phase of a wave file using wave editors but once you do you’re more or less stuck with the result. Instead, INSERT Flipper into your mixer channel INSERT and try it out in real time. Flipper can also be used to purposely generate out of phase signals or as a simple “Vocal eliminator” on stereo mixes (flip the phase of one side and mix the stereo tracks together in mono - whatever was centered in the mix will disappear).

Channel-Tool is a quite simple plugIn with which you can adjust the gain, the stereo-mix and the phase of the input signal.

Inverts the phase of either left or right channel.

Phase Bus

Its primary function is to shift the phase of an incoming audio signal. This is a critical function in fixing source signals that have phase errors in relation to one another, which can cause inappropriate cancellation or reinforcement of frequencies in a mix.
