Exporting Multiple from Label Track

[Gale Andrews]

Just discovered another issue that could be resolved in a track control panel for label tracks. I have a project with 1 stereo track and several mono tracks. The label track with which I was exporting selected only center-panned mono. Every export file had 2 channels. This could be avoided with a Mono button on the label track's TCP.

It could also be avoided with a rule change: If a label selects only center-panned mono then export mono for that label. If done with a rule change, it might be prudent to put the rule in Preferences->Import/Export. It should also be possible to select the rule: If any label in the export selects stereo then all the export files will be 2-channel. Currently, even if "Use Custom Mix" is selected there I still get 2 channels.

I am really not sure about your track layout and what you mean about labels "selecting" mono or stereo. Export Multiple just does a mix of all the tracks (using the uppermost of the label tracks), unless you omit tracks from the export by muting them.

"Use Custom Mix" in the Import/Export Preferences doesn't apply to Export Multiple. It's not a bug, but you can make it a separate feature request if you like (please start a new topic in Adding Features to Audacity to do that).

I will log as a bug that if you have a muted stereo and unmuted mono track then export multiple, the exported files are stereo. The best way around that for now is probably to remove the stereo tracks immediately before export then undo the remove immediately after export.

Thanks,

I am really not sure about your track layout and what you mean about labels "selecting" mono or stereo.

My one stereo track ends before the first label. A separate label track, when moved up, selects other parts that include stereo. This defines separate exports for CD and Podcast version.

I will log as a bug that if you have a muted stereo and unmuted mono track then export multiple, the exported files are stereo. The best way around that for now is probably to remove the stereo tracks immediately before export then undo the remove immediately after export.

Thanks for the suggestion, but since I'm already using SoX to combine the files for podcast I have another workaround. I just had to add a switch to my batch file .
