Description:

The Voice Tweaker Lite is a pitch transposer designed for monophonic signals such as voice, spoken or sung, or solo instruments. It can transpose the  pitch and formants independently, thus enabling both formant preserving pitch transpose and other more unusual effects. The Voice Tweaker Lite also features an automatic pitch correction function and auto vibrato. As a DirectX plugin it can be used with all DAW's (Digital Audio Workstation) or Sound editors with DirectX plugin support. It has been tested to work in the following environments: 

  Sound Forge 4.5
  Logic Audio Platinum 4.1
  Cubase VST 3.7r2
  Wavelab 3.0
  CoolEdit Pro 1.2
  Sonar 1.0
