Pitch Bend Dialog

In this dialog, you can gradually change the pitch of a sound using an envelope curve.

  • To open the Pitch Bend dialog, select the Process tab in the Audio Editor, and click Pitch Bend in the Time & Pitch section.

Pitch bend envelope

Allows you to edit the envelope curve to change the pitch of a sound. To add an envelope point, double-click the envelope curve. You can then drag the envelope points to customize the pitch bend envelope.

The following options to edit envelopes are available above the pitch bend envelope display:

  • Undo the Last Operation

  • Redo the Last Undone Operation

  • Deselect the Envelope Points

  • Delete the Selected Envelope Points

  • Reset the Selected Envelope Points

  • Reset the Whole Envelope

  • Flip the Envelope Around the Horizontal Axis

  • Reverse the Envelope Time Sequence

  • Toggle the Envelope Smoothing

Length Preservation

If this option is activated, you can specify how the length of the selection is affected by the pitch bend 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.

Range (Semitones)

Specifies the maximum range in semitones for the pitch change. When you change this value, this is indicated in the vertical ruler.
