Clone Ensemble has released Voice Trap, a VST/DX plug-in for Windows that allows you to remove or isolate a vocal from an audio track.
Traditionally you can remove the vocal from a stereo track by subtracting the left channel from the right but generally you only got mono output, the bass was missing, the mix sounded terrible, and you could only remove the vocal, not isolate it.
Voice Trap uses a sophisticated FFT algorithm that overcomes all these problems; the output is stereo, the bass frequencies are left untouched, the mix is largely preserved, and you can choose to remove the vocal OR isolate it.
Voice Trap is available as in VST and DirectX plug-in formats for Windows and costs $25. A demo version is available.
