Version 2.0.6 - Restoring Cuts

[Gale Andrews]

I installed 2.0.6 again so I could give you an exact description of the problem as I currently am editing.

The total WAV track time is 11:29:787.

I made a cut from 5:41:583 to 9:24:400. I then went back about five seconds so I could hear if it was to my liking. It was slightly off so I selected "undo". After the undo, the cut section started at 5:40:883, not 5:41:583. In other words, the start point of the cut shifted 1.7 seconds early. This shift did not happen in 2.0.5 or earlier.

Exactly how do you go back about five seconds?

To be clear, are you saying that the 1.7 seconds of audio is not lost, but that the restored region is offset 1.7 seconds to left?

Have you looked at the snap-to settings?
Do you mark the regions per mouse?
Does zooming in and out before undo change anything?
How does redo work, i.e. is it always the same outcome when you alternate (and change e.g the zoom inbetween)?

Hi:

LIke I just said, Snap To is "Off" in 2.0.6 and unchecked in 2.0.5.

I do not mark the regions with my mouse, I listen and then use the Selection Start and End boxes at the bottom of the screen to "fine tune" my start and end points. After making a cut, I go back about five seconds to hear if the result is to my liking. If it is not and I then undo the cut, that is where the difference is between 2.0.6 and 2.0.5. I stated that in 2.0.6, the starting point of the cut was placed 1.7 seconds earlier than it should have been. This did not happen in 2.0.5 so I am sticking with that version for now.

I did not do any zooming.

There is a way to install a "portable" version of Audacity and have that separate and distinct from the regular install. In this way you can have two different Audacities without constantly reinstalling.

I don't know how to do that in Windows and I can't find the instructions.

I can now reliably reproduce this.
Steps:
1 new project
2 generate tone 30 seconds: note 0 - 30 seconds is selected
3 USING THE SELECTION TOOLBAR ONLY: set selection start to 1 sec and selection end to 2 sec
4 cut
5 undo: 0 to 30 seconds is selected

If, at step 3, you use the mouse to select the region from about 1 - 2 seconds, then cut and undo, the selection from immediately before the cut is restored.

It seems that the selection is not being pushed on the undo stack when that selection is made from the selection toolbar instead of the mouse.

The same on Windows (with Audacity 2.0.7a)
It applies only to the selection via spin boxes (Selection Start, Selection Length). Selecting audio with brackets works properly, i.e. undo after cut restores this selection.

Now we're talking about a bug. Multiple people on different machines experiencing the same unintentional evil behavior.

You can install multiple Audacity versions on your Mac by creating a unique folder in /Applications and installing your Audacity to that (attach).

In my case the "real" install is Audacity 2.0.5 and the other is 2.0.3. The preferences and settings do not affect each other.

Hi Gale:

I click in the Selections Start box and go back 5 seconds with the down arrow. Similarly I do the same in the End box using the up arrow to advance 5 seconds so I can hear 5 seconds before and 5 seconds after the cut.

Yes, you are correct. 1.7 seconds is not lost but the restored region is offset 1.7 seconds to the left in 2.0.6. This does not happen in 2.0.5. and earlier.

Furthermore, you can have each Audacity version have its own preferences and other local settings by creating a "Portable Settings" folder, like this:

Excellent. Now you know I'm going to ask you where is that written other than right here, right now? I did a fly-over on both the on-line manual and the wiki and didn't find anything on the nitty-gritty of installs.

I found the Windows technique. It's pretty scary. I think that one just resets preferences on one Audacity rather than have multiple versions. I think the Windows people are stuck.

"Portable Settings" folder

I appear to have independent settings and preferences without such a folder.
