Chapter 1

< Formants >

A formant is an important element which determine the character of a vocal sound. It is a fixed overtone whose location is determined by the size of the vocal chords.

Conventional pitch shifters modify the pitch in a way that changes even the location of the formants (which by nature do not change). For example when a conventional pitch shifter raises the pitch, a Òduck voiceÓ is produced as if the vocal chords had shrunk, and when the pitch is lowered a Ògiant voiceÓ is produced as if the vocal chords had expanded.

The Voice Transformer modifies the basic pitch and the formant separately, allowing a variety of voice characters to be created.

MixBal (Mix balance)

Moving the fader above the middle will turn this on, and downward will turn it off.

< Channel 2(C.Pitch+F.Pitch) >

Coarse Pitch and Fine Pitch will change simultaneously to smoothly change the pitch.

< Channel 3 (C.Formant+F.Formant) >

Coarse Formant and Fine Formant will change simultane- ously to smoothly change the formant.
