Keyframing Level and Pan Changes

Each audio track has curves for level and pan, and you can add and edit keyframes to automate level and pan changes over time. This lets you create fade-ins and fade-outs, drop audio levels for voiceovers and other sound effects, and eliminate clipping.

For more information about using keyframes and editing curves, see Keyframes and Curves

Recording Keyframes

You can record keyframes for audio level and pan by clicking the Record button, then adjusting the dials or sliders in the Audio list, the HUD, or the Inspector. Alternatively, you can manually add a keyframe to the Level and Pan parameters in the Audio Track Inspector (any subsequent adjustments add a keyframe at the current playhead position). Recording keyframes for audio level and pan can be useful for trying out changes and hearing the results in real time.

Adding and Editing Keyframes

Level and Pan curves appear in both the Audio Timeline and Keyframe Editor.

  • Audio keyframes in the Audio Timeline appear as a flat sequence, allowing you to move their positions in time or delete them, or edit their values numerically.

  • Audio keyframes in the Keyframe Editor appear stacked, forming curves. To show the audio waveform behind the curve, choose the track name from the waveform pop-up menu on the upper-right side of the Keyframe Editor.

The Level and Pan parameters are adjusted via different numeric ranges:

  • Level curves range from –96 to 6 with 0 equivalent to 0 dB (unity gain).

  • Pan curves range from –100 to 100.

Because Level and Pan curves each use a different scale, it can be difficult to frame them at the same time in the Keyframe Editor.

To edit, add, or remove keyframes for animated Level and Pan settings, use the Audio Timeline or Keyframe Editor. For more information on working with the Keyframe Editor, see Keyframes and Curves.
