Pitch changes the pitch (frequency) of the selection. This is useful for converting instrument samples from one note to another. The new pitch is specified using a scale factor or using semitone and fine tune values.

| Setting | Description |
| Scale (%) | Sets the relative pitch by a percentage value. A value of 50% is equivalent to a downward shift by one octave. A value of 200 is equivalent to an upward shift of one octave and would make a voice sound like a chipmunk. A value of 75 would make a woman's voice sound like a man's. |

Semitone, Fine tune |
Sets the relative pitch in semitones (notes on a piano).
Given a tone at middle C, a the semitone value of 2
changes the tone of D. A value of -1 changes the tone to B.
A value of 12 makes the note one octave above middle C.
Fine tune sets a slight pitch adjustment in hundredths of a semitone. For example, a value of 50 changes a note from C to halfway between C and C#. |
| Preserve tempo |
If selected, a different, more complex algorithm is used to keep
the length and tempo the same. In terms of a voice
recording, this changes the pitch of the voice without changing the
speed at which the words are spoken. This option requires a
substantial amount of processing time and will affect the quality of
the sound.

Higher quality pitch changes may be possible using Time. Try the "Similarity pitch up" or "Similarity pitch down" presets in the Effect Chain Editor tool.
