Subject:Fade in/fade out bug in 10.0a

A month ago I reported a bug in the fade in/fade out feature - not the tool under the Process menu, but the feature that blends the edges of a selection when an effect is applied. I first discovered this bug while using the Smooth/Enhance tool - when applied to a selection (i.e. not the whole file), it amplifies the edges of the selection. With four repeated applications of Smooth/Enhance it amplifies the edges to clipping. The problem doesn't happen if I set the fade-in/fade-out times to zero. I found the problem also happens with the graphic equalizer.

I originally reported this problem on October 30. A tech support representative asked me to give them a project file demonstrating the problem, which I did on November 3. SInce then I haven't heard anything from Sony. This bug is a show-stopper for me - I won't be able to use 10.0 until it is fixed.

Has anyone else run into this problem? Can anyone at Sony tell me the status of this bug?

Have you tried changing the curves to linear fades? With certain effects that do not significantly modify phase, short fades with the default fast/slow curves can add gain.

I just tried it with linear fade-in/fade-out and it solved the problem. Thanks!

Can you explain why the default sometimes adds gain? Does this mean that this isn't really a bug?

Thanks again.

The default curves (slow-out/fast-in) typically sound "better" for longer fades or fades of two different sources. But are not unity-gain (they're parabolic).

In a wet/dry scenario, particularly over a short duration, they're more likely to add gain.

It's not a bug, per-se, but implies that it is worth re-evaluating whether they should be the default in an app like Forge.

BTW, you can change the defaults for all effects in prefs in Forge 10, and from the right-click context menu inside the plug-in dialog in Forge 9 (and 10).
