plugin that separates stereo audio into side and center channels. It's based on the "center cut" filter from VirtualDub. The algorithm's author, Avery Lee, describes it as follows:
The classic "vocal cut" filter, except that the output is stereo instead of mono. This is accomplished through FFT phase
analysis; the output will have some warbling in it, but stereo separation is preserved.
To use it, copy dsp_centercut.dll into your Winamp\Plugins directory and restart Winamp. Then go into Winamp's Preferences (CTRL+P) in the DSP/Effect Plug-ins section. Select "Center Cut v1.4.0" in the list, and you will see these options in the drop-down list below:
Center Cut - Sides: Removes the 'center' channel
(whatever is in both the left and right channels).
Center Cut - Center: Keeps only the 'center' channel.
Center Cut - Sides (Bass to Sides): Removes the 'center' channel, except for bass.
Center Cut - Center (Bass to Sides): Keeps only the 'center' channel, except for bass.
Remover: This is simply the difference between the left and right channels ((L-R)/2). Not very interesting compared to the other modes, but I included it for comparison.
