Pitch Changing

Pitch changing, or pitch shifting, is closely related to time compression and expansion. Similar algorithms are employed in a different way to achieve pitch changes without altering the length of an audio region.

Digidesign’s Pitch Shift plug-in allows you to change the pitch of an audio region up or down by as much as two octaves (plus or minus 24 semi-tones) with or without altering its length. As you can see in Figure 7.16, there is a checkbox for time correction in the Pitch Shift plug-in window that also enables the quality parameters at the bottom of the plug-in window, just like the Time Compression Expansion plug-in.
