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).
