This is about the most basic effect out there, and was originally written years ago, but some software products still do not it included with them, so I decided to make it. All this plugin does is a quick phase inversion (sometimes caled a 180 degree phase shift) on an incoming audio stream.
In order to use this plugin, you must have DirectX 6 or greater installed, as well as DirectX Media. You must also have a DirectX audio-compatible music application (like Paris, WaveLab, Cakewalk, etc) installed in order to use the plugin. It works on an audio stream of any channel count, at either 16bit or 32bit.
