Applying Filters to an Audio Clip

Applying audio filters to clips in Final Cut Pro is easy.

To apply an audio filter to a clip in a sequence
Do one of the following:
  • Select one or more clips in a sequence in the Timeline, choose Effects > Audio Filters, then choose a filter from the submenu.

    The filter is applied to all the clips you selected. If you selected video clips, the filter is applied to any audio items linked to those clips.

  • Drag an audio filter from the Effects tab of the Browser to a clip in a sequence in the Timeline.

    If you drag the audio filter to a video clip, the filter is applied to any audio items linked to that clip.

  • If a sequence clip is open in the Viewer, you can:

    • Choose a filter from the Audio Filters submenu of the Effects menu. The filter is applied to the clip in the Viewer.

    • Drag a filter from the Effects tab of the Browser directly to the Viewer.

If you apply more than one filter to an audio clip, the filters are applied serially. In other words, the first audio filter is applied, and then the resulting audio signal is fed through the next audio filter, and so on.

If you apply multiple filters to a clip, the order in which they appear in the Filters tab for that clip in the Viewer determines how the clip sounds. Although the initial order of filters in the tab depends on when they were applied, you can change the order at any time.

To apply multiple filters to a clip in a sequence
Do one of the following:
  • Continue to apply more filters to the clip, one at a time, using any of the methods described previously.

  • Shift-click or Command-click to select multiple filters in the Effects tab of the Browser, then drag them all to one or more selected clips in a sequence in the Timeline.

    Filters are applied to clips in the order they appear in the Effects tab.

Filters can also be copied, along with all of their settings, and pasted into one or more clips in the same sequence or in another sequence.

When you copy a clip in the Timeline, you also copy all of that clip’s settings. These settings include filters that have been applied to the clip. Instead of pasting the clip, you can paste only that clip’s filters into other clips that you’ve selected. To do this, you use the Paste Attributes command.

To copy filters from one clip and paste them into another
  1. Select a clip in the Timeline with a filter applied to it.

  2. Copy the clip.

  3. Select one or more clips in the Timeline to apply the filter to.

  4. Choose Edit > Paste Attributes (or press Option-V).

  5. In the Paste Attributes dialog, select these options:

    • Scale Attribute Times: Shrinks or stretches the keyframes of your copied clip attributes to fit the duration of longer clips you may paste them into.
    • Audio Attributes: Determines which attributes of the audio clip are pasted.
    • Filters: Applies the parameter values and keyframes you have set for all filters in the clip you copied.

      Important: Pasting attributes into clips that have different frame rates will produce erratic results.

  6. Click OK.

    The filters are pasted into the clips you selected.
