Hi,
here are some notes on the auto duck effect.

The requirements of the Auto Duck effect are that:
1. The tracks whose volume is going to be reduced are selected, and a  
time-range is selected to include all the audio you want to be modified.
2. The control track is the next track after the above tracks, and it isn't 
selected.

So if you've got one music track and one narration track in the project:
1. Make sure that the music track is the first track. You can move tracks  up 
and down the table using the tracks context menu (application key).
2. Arrange for the music track to be selected and the narration track 
unselected. (pressing enter toggles whether the focussed track is selected)
3. Select a time range to include all the audio in the selected track: press j, 
and then shift + k.
4. Open the Auto Duck effect from the effects menu, and press Enter to press 
the default OK button.

In fact the Auto Duck dialog contains a number of controls for setting  various 
parameters which you may want to adjust. All the time parameters are specified 
in seconds, and the volumes in db.
1. The first control is a panel which graphically illustrates the parameters, 
and you can just ignore this.
2. The duck amount is the reduction in volume.
3. The maximum pause is the maximum time that the volume in the control  track 
can be below the specified threshold before the volume in the  selected tracks 
is faded up again.
4. The time over which the volume  in the selected tracks is faded down to the 
reduced volume is made up of two parts: the time before and the time after the 
time when the volume  in the control track exceeds a threshold. These are known 
as the outer  and inner fade down lengths.
5. Similarly, there are outer and inner fade up lengths.
6. The threshold is the volume in the control track which if exceeded causes 
the volume in the selected tracks to be reduced.

Note that whatever value of maximum pause is set, it is always at least the sum 
of the outer fade down and fade up lengths.


David.
