The Pitch section provides controls for pitch shifting the selected audio. Use the Pitch control to transpose the pitch from as much as –36.00 semitones (–3 octaves) to +36.00 semitones (+3 octaves), with fine resolution in cents, depending on which Range button is enabled (2x, 4x, or 8x). X-Form also lets you transpose the formant shape independently of the fundamental frequency.
Displays the transposition amount in semitones. You can transpose pitch by as much as –36.00 semitones (–3 octaves) to +24.00 semitones (+3 octaves), with fine resolution in cents, depending on which Range button is enabled. Adjust the Pitch control or click the Transpose field and type the desired value. The default value is 0.00 semitones, or no pitch shift.
Displays the pitch shift amount as a percentage. You can shift pitch by as much as 12.50% (–3 octaves) to 800.00% (+3 octaves) depending on which Range button is enabled (2x, 4x, or 8x). Adjust the Pitch control or click the Shift field and type the desired value. The default value is 100%, or no pitch shift.
Audio with a fundamental pitch has an overtone series, or set of higher harmonics. The strength of these higher harmonics creates a formant shape, which is apparent if viewed using a spectrum analyzer. The overtone series, or harmonics, have the same spacing related to the pitch and have the same general shape regardless of what the fundamental pitch is. It is this formant shape that gives the audio its overall characteristic sound or timbre. When pitch shifting audio, the formant shape is shifted with the rest of the material, which can result in an unnatural sound. Keeping this shape constant is critical to formant correct pitch shifting and achieving a natural sounding result.
The Pitch section of X-Form lets you pitch shift the formants of the selected audio independently of the fundamental frequency. This is useful for achieving formant correct pitch shifting. It can also be used as an effect. For example, you can formant shift a male vocal up by five semitones and it will take on the characteristics of a female voice.

The Formant field displays the amount of formant pitch shifting from –36.00 semitones (–3 octaves) to +36.00 semitones (+3 octaves), with fine resolution in cents. Adjust the Formant control or click the Formant field and type the desired value. The default value is 0.00 semitones, or no formant shift.
