Sound Effects

Similar to how you can create keyframes for motion, you can create a keyframe for both sound effects and the Volume Envelope. This will allow for an interpolation between two effect values upon playback. The Effect Stack view is used to edit a sound clip by layering effects onto the clip. The properties of these effects can be adjusted to fine tune the desired result.

When you select an audio clip, the Effect Stack view will display the parameters of that current audio track. If there are no effects added, the only effects that will appear are the Gain and Volume Envelope options. You can add effects by selecting the Add Effects button. Once your effects are added to the effect list in the Effect Stack, you can begin to apply your keyframes in the Effect Stack view.

  1. Access the Effect Stack view by doing one of the following:

    • Select Windows > Effect Stack.

    • Click the Add View button and select Effect Stack.

  2. Move the playhead to the location where you would like to add a sound effect keyframe.

  3. In the Effect Stack view, select the plus sign to the right of the effect value to add the first keyframe.

    A keyframe is added and will be visible in the Effect Stack view.

    NOTE To add an effect to the Effect Stack view, select Add Effect.

  4. In either the Effect Stack view or the Timeline view, move the playhead to the location where you would like to add the second keyframe.

  5. Select the plus icon to the right of the effect value to add a second keyframe.

    NOTE Selecting the left and right arrows will allow you to shift between keyframes.

  6. In the Effect Stack view, enter sound effect parameters for your second keyframe by clicking the numerical value to the right of each effect and entering a new value.

    NOTE Moving the playhead to a new location and changing the effect value will create a keyframe automatically.

When you play back your storyboard, the effect value will interpolate from the value of the first keyframe to the value of the second keyframe.

NOTES

  • The zoom slider in the lower-right corner of the view allows you to scale the timeline. You may use the horizontal scrollbar to focus on a certain region.

  • You may perform scrubbing by dragging the playhead in the both the Effect Stack view and the Timeline view

Use the Delay effect to make a voice echo across a chasm or the Pitch Shift to make a voice sound like a cartoon mouse. To learn more about all the available sound effects, see Effect Stack View.

All effects applied to the audio clips can be played back in real time. You can scrub through the timeline to listen to the affected audio clips. Because the effects applied are non-destructive, you can remove or further adjust the parameters of your effects without permanently changing the original audio file.
