Edit Menu: Remove Audio or Labels

Cut 
Removes the selected audio data and/or labels and places these on the Audacity clipboard. Any audio data or labels to the right of the selection are shifted to the left. Only one item can be on the clipboard at a time, but it may include multiple audio or label tracks and multiple audio clips.

Delete 
Similar to Cut, but removes the audio data and/or label that is currently selected without copying it to the Audacity clipboard.



Split Cut 
Same as Cut, but none of the audio data or labels to right of the selection are shifted. This is therefore a useful command to remove one label of a group of labels without affecting the other labels (be sure to select only in the label track unless you want to cut the audio as well as the label).

A gap is thus left behind in the audio track which splits the existing audio clip into two clips that can be moved independently using Time Shift Tool.

Split Delete 
Removes the selected audio and/or labels without placing these on the Audacity clipboard, but like Split Cut does not shift the following audio or labels.

This is therefore a useful command to remove one label of a group of labels without affecting the other labels (be sure to select only in the label track unless you want to delete the audio as well as the label) - see Example 3 below.

As with Split Cut the preceding and following audio are now separate clips that can be moved independently.

Silence Audio 
Replaces the selected audio with silence.

Trim Audio 
Removes all audio from the current clip except the selected part, creating its own clip from the remaining audio. If there are other separate clips in the same track these are not removed or shifted unless trimming the entire length of a clip or clips (note in the "After" image below that the audio in the clip to the right is unaffected).

Examples of removing labels
1) Remove audio and label using Delete 
 * [[image:RemoveAudioAndLabelBefore.png]]
 * [[image:RemoveAudioAndLabelAfter.png]]
 * Result: both the audio and labels following the deleted section move to the left. The labels still correspond to the same audio regions.

2) Remove label using Delete 
 * [[image:RemoveLabelBefore.png]]
 * [[image:RemoveLabelAfterDelete.png]]
 * Result: the labels following the deleted section move to the left. The labels no longer correspond to the same audio regions.

3) Remove label using Split Delete 
 * [[image:RemoveLabelBefore.png]]
 * [[image:RemoveLabelAfterSplitDelete.png]]
 * Result: the labels following the deleted section do not move to the left. The labels still correspond to the same audio regions. This is a quick way to delete a label without affecting any other labels on the Label Track.
