Time-remap audio pitch
The speed graph of the Time Remap property directly relates to the pitch of an audio file. By making subtle changes
to the speed graph, you can create a variety of interesting effects. To avoid screeching audio, you may want to keep
the Speed value below 200%. When the speed is too high, use the Levels controls, located under the Audio property,
to control the volume.
You may hear clicks at the beginning and end of an audio (or an audio and video) layer after setting new In and Out
points in the Time Remap graph. Use the Levels controls to remove these clicks.
