Searching on the forums and the Audacity wiki, I can only find information indicating that all tracks are merged into a single file. This file is named based on the last of the label tracks (i.e. “Label track 3” in my example above). I cannot find any information explicitly stating that exporting only a single label track is not possible, however.
It seems this would be a common task, so I was assuming I am missing it in the GUI or details about it in the forums somewhere. Or is it not possible and requires a feature request?
Is this stable for many label tracks and/or long audio files? The example I provided was a simplified example. And deleting and undoing many tracks one longer audio files seems potentially unstable.
I’m surprised by this. Based on my experience with software in general, I would expect the currently selected label track to be exported (or either the first or last, if no label track is selected). And to export multiple/all only when multiple tracks are selected. Possibly having a preference to change this behavior.
Perfectly stable for me.
I assume that you make regular backups?
That’s quite different from how exporting audio works.
When exporting audio, all non-muted tracks are mixed to produce a single file.
When exporting labels, all label tracks are merged to produce a single file.
When exporting audio, there is an additional option “Exported Selected Audio”. The equivalent command for labels (which Audacity does not have) would be a command to “Export Selected Labels”.
What is your actual use case that requires exporting a single label track?
