Removing labels together with their associated audio

Including the audio track in the labeled region to be removed

In most cases when you remove parts of the label track, you will also want to remove the corresponding audio so that the remaining labels are still synchronized with their original audio. To remove the audio region as well as the label region, either drag the selection upwards to include the audio track or enable Tracks > Sync-Lock Tracks. Sync-Locking synchronizes audio tracks with the label tracks beneath when you change the length in label track or audio track, even if you don't select in all the tracks.

Keyboard use: To include the audio track in the selection, press UP then ENTER. See Selecting using the keyboard.

A convenient way to select and delete the exact area of an individual region label together with its corresponding audio (moving the following audio backwards) is to click in the label, then press Enter followed by DELETE or BACKSPACE. If your Interface Preferences are set to "Retain labels if selection snaps to a label edge", this retains a point label at the former left-hand edge of the region.

Keyboard use: Use UP or DOWN then ENTER if needed to select the audio track, then repeat as needed to also select the label track. Then Tab into the label to be removed, press Enter then DELETE or BACKSPACE.

Including the label track when removing or inserting audio

When you select unlabeled audio that needs to removed you must include the label track in that selection if you want any labels following to right of the removed selection to remain synchronized with their audio. Similarly if you insert audio, the label track must be included to ensure label synchonization. To include the label track, drag the selection (or cursor) down into the label track or enable Sync-Lock Tracks as above.

Keyboard use: To include the label track, press DOWN then ENTER.

Example

You have identified a section of applause at the end of Track-3 that you want to remove and have labeled this section with a region label.

Select in the audio track from one edge of the label to the other then drag down into the label track, or simply click in the text of the "clap" label.

Then use the shortcut CTRL + K to make the deletion. As you can see, the label for Track-4 and its audio both move back (leftwards) on the Timeline thus keeping the label for Track-4 at the start of that track. If you already had the labeled audio selected on its own, you could equally have dragged either edge of that selection down into the label track.
