We designed the VariPitch algorithm with high quality pitch
change, chorus and double tracking effects in mind. You can use it
on monophonic as well as polyphonic material with dual mono or
stereo input. For music applications, VariPitch is the best and
most unobtrusive pitch control device in the industry today.
Due to intelligent splicing, you can also use VariPitch for demanding applications such as real-time pitch change of entire master tracks when converting frame rates between video and film, and you can lock channels to preserve phase relationship while applying pitch change.
The up and down pitch range is +/- one octave, while delay, feedback, cross-feedback and filters are available for effect purposes.
