Optional - Using the Auto Duck Effect
- Peter 13May12: And if we did leave this out, it would make this tutorial more applicable to legacy as well as current Audacity - and thus we could re-consider trimming the equivalent Wiki tutorial http://wiki.audacityteam.org/wiki/Creating_a_simple_voice_and_music_Podcast_with_Audacity
Have a look at the Auto Duck page for an overview of how it works.
If you've decided to try the Auto Duck effect you first need to undo the envelope you created in the step above. Repeatedly chooseuntil all the envelope control points are gone.
Note that to use this effect the narration track (which Auto Duck calls the control track) must be below the music track. So we need to drag the music track above the narration track. Click on the Track Control Panel of the music track (being careful not to click on the buttons, sliders or the drop-down menu) and drag the music track above the narration track.
With the music track above the narration track, select a portion of the music track that overlaps one of the narration clips, with two or three seconds extra on each side. Choose. For now, accept the default parameters (-12 dB, 1 second, 0.5 seconds, 0.5 seconds, 0 seconds, 0 seconds, -30 dB) and click the button. After the effect completes, listen to the result. If you don't like it, choose . Bring up the Auto Duck dialog again and change the parameters. Continue trying different parameters until you get a result you like.
When you have settings for the Auto Duck effect that you like, chooseone more time. Then click on the Track Control Panel of the music track to select the entire track. Choose one last time. Click the button to apply the Auto Duck effect to the entire music track.
Note the difference between this and the use of Envelopes: Auto Duck has altered the music track, and the effect is permanent.
