Question

Audition clips are audible outside of the edits

Hello, 

I am using Adobe Audition for sound design for a short film for the first time and am finding that the clips I edit are audible outside of the edits. The sound does not start or stop exactly where I’ve edited it; it starts a few frames before the clip and continues a few frames after. This happens whether I have applied a fade or not. It seemingly creates its own fade, which exists outside of the visible clip, making it impossible to achieve the accuracy I need. Is there a way to fix this, or turn off this feature? 

Thank you!

-John

There are two settings in Edit>Preferences>Data that set the values for crossfade smoothing. The delete/cut setting should be 2ms, but the one that may well be causing your difficulties is the 'all edit boundaries' one, if it's set too high. You shouldn't reduce either of these to zero, because then you will inevitably get clicks at transitions - that's why they are there at all.

 

Let's say that you are running at 30fps with your video. One frame of this will last 33.3ms, so any smoothing time that's less than this value should be fine. The sort of figure that would keep the clicks at bay but still give you audibly clean cuts is about 5ms. But if, for instance, it was set at 65-70ms then yes, you are likely to get a 2-frame bleed between clips.

 

The other thing that it's not uncommon to do is to edit the copy of your source audio that you are using so that there is a couple of hundred ms of silence at the start and finish of each clip - then you won't have the problem anyway. Yes I do realise that this isn't always possible...

    Thanks for replying! When I read your response, I figured that must be exactly the problem. However, I’ve tried changing those values and nothing is changing. I’ve tried unchecking both of those features, lowering and raising the values in many ways and am still getting the same bleed. I found another feature in the clip menu: “Automatic Crossfades Enabled.” I disabled it and am still getting the exact same automatic fade on every clip. Then there’s a “fade in” and “fade out” feature and both are set to “No fade.” Still getting fades, though. I tried restarting the software as well as the computer and still no change.

    This does seem like a feature intended for user convenience but it works against any kind of detailed editing, so I’m really hoping there’s a way to turn it off. Any other ideas?

    Thanks!
