AnalogX Vocal Remover works on the same principles that the hardware
removers do - that in most instances vocals are equally mixed in both
channels, and can identified and therefore removed by simply changing the
phase on one channel by 180 degrees. While this won't remove vocals in all
instances, it does work in many cases, and can sometimes be used to
remove bass or breakbeat sections as well, which I find to be GREAT for
sampling! Depending on the effects used on the vocals, sometimes the reverb
or ambience of the vocals is left. In order to use the WinAmp Vocal Remover,
you must already have WinAmp installed in your system; it REQUIRES a
stereo sound stream, and supports only 16bit data types.
