Missing Project Section Bars

Windows 10, Audacity 2.4.2

This is my first post so apologies if I’m using any wrong terminology. I have recently successfully updated from v.2.3.3. My main Audacity use is to prepare artist music submissions for recorded radio shows. As such I maintain projects for each show hour and edit them as required, adding some and deleting others. In the last few days the vertical grey bars dividing the songs and links have disappeared, leaving the project as a whole. This isn’t a disaster but makes selection more difficult.

I’ve been investigating features and trying new ones and I suspect I’ve inadvertently changed a setting. I’ve spent time reading the Audacity manual but can’t find anything resembling a setting, unless I’ve failed to identify one. I’ve attached screenshots, one of the current situation and an old project showing the vertical bars. Can anyone suggest a solution to restore them? Thanks.

Image “Untitled1.png” appears to show “splits” (vertical black / gray lines: https://manual.audacityteam.org/man/edit_menu_clip_boundaries.html#split)

Image “Untitled.png” does not show “splits”. If this is what you mean by “the vertical grey bars dividing the songs and links have disappeared”, perhaps you inadvertently “joined” the clips to create a continuous track (for example, you may have pressed “Ctrl +J” when you meant to press some other keyboard shortcut).

Thanks Steve, that’s always possible, due to ‘finger trouble’. I’ll try to be more careful and monitor the situation.

Should it happen again, you might be able to bail yourself out by using Edit > Undo.

Thanks for that, Jademan. I’ve reinstalled Audacity; 35 years at the IT coalface showed me how easy it is for software to be corrupted.

I’ve indentified the cause with Jademan’s suggestion. The splits went after applying the Change Tempo effect to the entire project but returned after an Undo. I’m sure that didn’t happen under v2.3.3. Is this to be expected or have I identified a bug? A workaround is to save the project with the tempo unchanged.

It was a bug. It has been fixed for the next Audacity release.

Note that the problem does not occur if you select the option “Use high quality”.

Another workaround is to select each audio clip in turn and apply the effect to one clip at a time. This is not a great workaround because Change Tempo tends to glitch at the start of the selection (even when using the “high quality” setting).

Many thanks Steve, all useful information. I hung up my developer’s hat nearly 20 years ago but it seems I’m still system-testing. :slight_smile:
