Gain sliders moving during playback

I have created a playback file that consists of 4 tracks. 3 of the tracks were created and mixed together in another project originally (with 2.1.1) and then copied and pasted into the master project. The 4th track was also created in another project (2.1.1) and copied and pasted into the master project.

Here’s what I’m seeing: during playback of the master project, as I move a gain slider around seeking to find a good overall mix, I’m watching gain sliders in other tracks moving, as if in some way the tracks have been linked, when I know of no way this could be occuring. The gain sliders move don’t seem to be fixed though, eventually moving back to where they started. Also, interestingly, I don’t think I’m hearing what would be obvious changes in the output to correspond with the changes. (?)

Is this some new feature I’m unaware of? A bug?

Thanks for any assistance. I’ve been using this version for over a month and tonight is the first time I’ve seen this happen.

What version of Windows?

Gain sliders are not linked, though some would like that feature.

I suggest you uninstall the Audacity version you have now then download Audacity from us at http://audacityteam.org/download/windows. Half way through installation, check (tick) the “Reset Preferences” box then confirm you want to reset preferences when you launch Audacity.

Same as me, then. There is no known reason for what you describe.

Removed Audacity with Revo Uninstaller, then replaced with new download as instructed. Situation is still occurring.

I previously incorrectly stated that one of the projects (with 3 tracks copied to master project) was done with 2.1.1 when it was actually created with 2.0.3. on another computer.

I have just opened that master project in that computer (also running win 7 x64 sp1) with 2.0.3 and the situation is not occurring there.
(And I just realized that I probably shouldn’t have opened a project saved in 2.1.1 in the older version Audacity, in fact I didn’t think it was doable (?))

Again, although the sliders on all of the other tracks move when I just even click on the gain button for the 4th track, I don’t hear an audible difference, and when I release the button, the sliders revert back to their preferred positions. When I move the gain button either left or right, the other sliders move in synch. I just discovered that the same thing is occurring with the pan sliders.
When I open and use the mixer board, I don’t see the problem there, but if I leave that board open and manipulate the gain/pan button on the main screen, and see the change there, it doesn’t also show up as changed on the mixer board.

This is occurring now on all my projects that have been created in a similar manner. Again, not a problem, as it isn’t actually changing my settings or sound, but it is quirky.

Thanks for any further assistance.

All 2.x versions use the same basic project format. If some data parameter is saved in the 2.1.1 project that 2.0.3 does not recognise, it should ignore it.

Suppose you File > Export Multiple… each track as a WAV, quit Audacity then import the WAV’s into an empty project in 2.1.1, does that get rid of the problem?


Gale

Thanks.

Yes, that seems to work. When I imported the files into the new project I copied them into the file rather than reading them direct from the old.

I responded to quickly . I just noticed that it is still doing this even with the new project. Originally, I hadn’t closed and rebooted Audacity. After doing so, I noticed the behavior was the same.

I can’t reproduce this on W7-HP 64-bit on either the latest 2.1.1 release or the latest alpha nightly 2.1.2 r0f79a77 12-aug-15

I can’t reproduce anything like it either, even if I paste tracks from another project.

Right-click over audacity.exe, choose Properties then the Compatibility tab. Have you got Compatibility mode turned on, or set for old versions of Windows?

Did you make changes to the system just before this started happening? Such as installing an app that modifies window behaviour?

No, compatibility mode is not on; No apps installed recently as far as I know that would modify window behaviour.

I did discover something else I neglected to notice that might be related. In the original 3 recorded tracks done with Audacity 2.0.3, the default was 44100, 16 bit. When I moved to version 2.1.1 on this other system, the default was 44100, 32 bit floating. I recorded the 4th track in this other system with the new defaults, and when I opened and copied the original 3 tracks in 2.1.1 they were set to 4410, 32 bit floating, rather than 4410, 16 bit. Could this be causing the quirk?

Thanks,

The default quality in 2.0.3 and 2.1.1 (supplied by us) is the same - 32-bit float.

Pasting in a track from a project that defaulted to 16-bit into a 32-bit project doesn’t make the gain sliders gang together for me (nor would I expect it to).

Ok, I must have changed the setting in 2.0.3 to 16 bit. In any case, just looking for anything that might make a difference. Thanks for the feedback.

P.S. I have 19 different final projects, all created in the same manner, and I’ve been working through them one by one, and so far all are showing this happening. Just to be clear, the behavior doesn’t always happen immediately, I find that when I left click and drag the gain/pan button, that if I hold down the button for an extended period, say 1-2 seconds, then I see the movement in the other tracks gain/pan buttons. This often happens even if I don’t move the slider, just depressing the gain/pan button. Also, after releasing the button in it’s new position, the other buttons return to their origin after a slight lag.

Thanks for the extra information, though I still don’t see it happening for me.

In case track height or layout is something to do with this, can you post a screenshot of the Audacity project window? Please see here for how to attach files: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1


Gale

Thanks. screenshot attached. Only other thing to be noted at this point is that I’m mixing mono and stereo recorded tracks. I’ve tried this with the solo tabs in use and with the mute tabs used and it still occurs.

I don’t think it is relevant but you have audio behind time zero (see “Selection Start” in Selection Toolbar at the bottom of the Audacity window).

I still cannot reproduce your issue. Can you try in the latest 2.1.2-alpha development build from the top of http://gaclrecords.org.uk/win-nightly/?


Gale

Thanks. Yes, there is a latency correction from overdubs on some tracks that I need to correct for still.

I will try the new build in a few days.

If this is a real stumper, use my favorite mental trick. If somebody wrote you a big check, how would you force this to happen in a well-behaved Audacity? What condition causes sliders to move?


Koz

I downloaded the latest 2.1.2 alpha today and unzipped it to my desktop, also copied it to another computer also running win7 x64 sp1, that has never had any version of Audacity.
On both computers with the alpha run the behaviour was evident on the same small music project.

Alan

Interesting… since the behaviour itself is not always well-behaved! meaning that it doesn’t happen immediately upon demand all the time, and often only upon a lag when depressing the gain/pan button (imagine me moving the sliders around seeking to find a good level or position, and then after a second or two I see the other sliders move). But, the movement of the other tracks sliders is usually always in complete synch when it does occur, eg. if I move one tracks slider all the way to the left, all the other sliders (at least the viewable sliders above that track) will move to that far left position.
