The Bend
command allows you to draw an envelope that increases or decreases the
pitch of a sound file over time.
From the Effects menu, choose
Pitch, and then
choose Bend
from the submenu.
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.
Adjust the envelope to achieve
the desired sound:
Drag the small envelope points up
or down.
To create a new envelope point,
double-click the envelope.
To delete an envelope point, right-click
it and choose Delete
from the shortcut menu.
To change the fade curve between
two points, right-click an envelope segment and choose a command from
the shortcut menu:
Fade Type
Fade In/Out Envelope
Linear Fade
Fast Fade
Slow Fade
Smooth Fade
Sharp Fade
Hold
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.
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).
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.
