Making Real-Time Audio Filter Adjustments
You may find it easier to make adjustments to an audio filter while the clip it’s applied
to plays. This way, you can hear how the adjustment sounds as you modify the filter’s
parameter.
To make real-time changes to an audio filter parameter
1 In the Timeline, double-click the sequence clip with the audio filter you want to modify.
The sequence clip opens in the Viewer.
2 In the Viewer, click the Filters tab to see the clip’s audio filter parameters.
3 Move the playhead to the position in your clip where you want to make a filter parameter
change.
4 Play the sequence.
5 Adjust the controls for the audio filter parameter you want to change.
You hear your changes immediately.
6 When you’ve finished making changes, stop playback.
When you release the mouse button, your change is applied to the filter parameter.
Looping Playback While Making Real-Time Filter Adjustments
Ordinarily, playing back your sequence clip in the Viewer plays back your entire clip, from
the starting position of the playhead forward. If you instead want to loop a limited section
of your clip as you adjust a filter’s parameters, you can turn on Looped Playback, set In
and Out points to determine how much of your clip plays back, and use the Play In to
Out command to loop playback.
