Pitch

Effects Menu

From the Effects menu, choose Pitch and choose a command from the submenu to change the pitch of a selection.

How do you want to change pitch?

Bend

The Bend command allows you to draw an envelope that increases or decreases the pitch of a sound file over time.

  1. From the Effects menu, choose Pitch and choose Bend from the submenu.

  2. Drag the Range slider to determine the maximum and minimum pitch change in semitones (half-steps). Example: A range of twelve half-steps (one octave) allows an increase or decrease of the pitch by an octave.

  3. Adjust the envelope to achieve the desired sound:

You can create up to 16 envelope points. Click the Reset Envelope button to remove all but the outer two envelope points.

  1. Select the Preserve original duration check box if you do not want pitch bending to change the size of the sound file. This setting works best when performing small pitch corrections (up to +/- 2 semitones).

  2. Click the OK button.

Displaying the waveform

When your selection is small, the waveform is automatically displayed in the envelope graph. Perform the following steps if the waveform is not displayed.

  1. Select the Show wave check box.

  2. If you're working with a stereo file, choose a setting from the drop-down list to specify which channels are displayed.

Shift Sound Forge only

The Shift command allows you to change the pitch of a sound with or without preserving the duration of the selection.
