Some Thoughts on Audio Ducking (AD)

[Terfyn]

I had used AD before but on a recent video I wanted the music track to respond to first, live audio from the video plus a voiceover. Having set it up I discovered that the AD would not respond to a low volume level on another track, in this case, the voiceover. I corrected this by upping the System Sounds on the Windows Volume Mixer. ( For those not in the know - right click on the speaker symbol on the TaskBar - Open Volume Mixer - adjust the System Sounds) I re-recorded the voiceover and the AD responded normally. The settings used were Ducking Level = 60 and Sensitivity = 1, the Ducking Level seemed to have little effect whatever the setting but the Sensitivity was higher the lower the setting. The final rendering was satisfactory for volumes.

One criticism of the AD is the time it takes to move from the higher to the lower volume - almost a second. This should have an adjustable setting even if it is limited to Normal and Sharp. The "slope" can easily be changed by sliding the lower volume node towards the upper volume node manually but if there are a number of AD actions, then every one has to be altered after the AD has been applied -not good.

So decent volume on the non AD audio tracks and patience to change each lower volume node.

Yes but it is simplistic and does not mention that the "trigger" track need to be at a reasonable volume level, nor is there mention of the shallow slope from full volume to ducking level. In one case the lowered volume finishes at a point with no "flatlining"!
I like Audio Ducking and have used it quite a lot but it does need tweaking to improve the cut off speed.
