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.

Change the pitch of an audio layer

  1. In a Composition or Timeline panel, select the layer you want to remap.
  2. Choose Layer > Time > Enable Time Remapping.
  3. Click the Graph Editor button in the Timeline panel to display the Graph Editor, if necessary.
  4. Click the Choose Graph Type And Options button at the bottom of the Graph Editor and choose Edit Speed Graph.
  5. Move the current-time indicator to the frame where you want change to begin, and then click the Add A Keyframe button.
  6. On the speed graph below the keyframe, drag a marker, watching the Speed value as you drag.

    • To lower the pitch, drag the speed graph marker down.

    • To increase the pitch, drag the speed graph marker up.

Remove clicks from new In and Out points

  1. If necessary, choose panel > Audio.
  2. In the Timeline panel, select the audio (or audio and video) layer to which you applied time-remapping.
  3. Expand the layer outline to display the Audio property and then the Audio Levels property.
  4. Move the current-time indicator to the new In point and choose Animation > Add Audio Levels Keyframe.
  5. In the Audio panel, change the decibel value to 0.0.
  6. Press the Page Up key on your keyboard to move the current-time indicator to the previous frame.
