Amount of Shift

Semitones

Allows you to specify the amount of pitch change in semitones.

Cents

Allows you to specify the amount of pitch change in cents.

Find Current Pitch of Audio Selection

Analyzes the pitch of the selected audio and displays it below this button. This option is only available for audio files.

According to the current pitch, compute the required shift to match the key hereafter

Click to adjust Amount of Shift parameters automatically, based on the detected pitch and the pitch specified in the value field below this button. This option is only available for audio files.

Pitch field

Specifies the resulting pitch.

Method

Length Preservation

Specifies how the length of the selection is affected by the operation:

  • A setting of 100 % means that the length of the audio remains unchanged.

  • A setting of 0 % means that the program behaves like a tape recorder, when the speed of its tape is changed. For example, if you raise the pitch by one octave, the audio is half as long.

For large transposition values, the lower this setting, the better the quality of the effect.

Accuracy pop-up menu

Allows you whether to favor duration accuracy or pitch accuracy when pitch shifting.

  • If Favor Duration Accuracy is selected and the Length Preservation is set to 100 %, the resulting audio after pitch shifting is the same length as the source audio.

  • If Favor Pitch Accuracy is selected, the resulting audio after pitch shifting might have a slightly different length than the source audio.

Correct Formants

If this option is activated, changing the pitch of vocal material gives a more realistic result. When processing non-vocal material, leave this option deactivated, because it uses a slightly slower processing algorithm.

Note

This algorithm might cause a noticeable increase in signal level.
