Vocal Remover
"So you want to impress your friends with your singing skill, but they
only like to listen to those boring old top-40 songs; and that brand new
Karaoke machine you just bought is broken. What can you do? Is everything
lost? NO! Don't do anything drastic! There's still hope - Introducing
AnalogX Vocal Remover!
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 DirectX
Vocal Remover, your application must support DirectX Audio Plugins, and
must also support either realtime or non-realtime processing (such as
Paris, Cakewalk, WaveLab, CoolEdit, etc). Vocal Remover REQUIRES a stereo
sound streams, and supports either 16bit or 32bit data types.
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."
