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 then 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:

4. Drag the small envelope points up or down.

5. To create a new envelope point, double-click the envelope.

6. To delete an envelope point, right-click it and choose Delete from the shortcut menu.

7. To change the fade curve between two points, right-click an envelope segment and choose a command from the shortcut menu:

• To move all envelope points, press Ctrl+A and drag when the envelope has focus (the cursor will be displayed as a ).

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

4. 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).

5. Click the OK button.

Displaying the waveform

Choose a command from the Show wave drop-down list if you want to display the waveform in the envelope graph.

If you’re working with a multichannel file, you can choose to view individual channels or the mixed waveform.

The waveform is unavailable when the selection is greater than 300,000 samples.

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