Label Tracks can be used to annotate an audio file. They can be used
for lyrics, markers, or notes, and they can even be used to save
To create a Label Track, select New Label Track from the
Project Menu. Alternatively, simply
click or select where you would like to place a label, and choose
Add Label at Selection from the Project Menu,
and a Label Track will be created automatically if one doesn't already
To add a new label, click or select where you want the new label to appear,
then select Add Label at Selection from the
Project Menu, then type the name of the
label, and finally press Enter or click outside of the label.
In addition, you can use the Add Label at Playback Position command
from the Project Menu if you want to
add a label at a certain place while you are listening. By default, this
command has a shortcut of Control+M.
To edit the name of a label, click anywhere in it.
Zoom in first if there are too many labels crowded together and you
are unable to click on the one you want. When a label is selected
for editing, it looks like the first label below:
When editing the name of a label, you are limited to using just
the backspace key for editing. There is no way to move the
insertion point to append a letter to the beginning of a label.
Once a label is selected, you can move to the next label by pressing
Tab, and move to the previous label by pressing Shift-Tab.
To delete a label or multiple labels, select the area containing the
label flags you wish to delete, and choose Silence from the
Edit Menu. Alternatively you can delete
an individual label by clicking on it and pressing Backspace until you
have deleted all of the characters in the label, then pressing Enter.
To move labels, use the normal editing commands like Cut, Copy,
Paste, Delete, and Silence.
You can save a selection in a label. When you create a new
label, the left selection edge determines the position of the label's
flag. However, the right selection edge is also stored in the label,
and when you click on it, the full original selection will be restored.
If you wish to apply this selection to only a subset of the tracks,
shift-click in the label area to the left of each track's waveform
to change whether each track is part of the selection or not.
Exporting and Importing label tracks
Label Tracks are saved when you save an Audacity Project, so if you
just want to continue using the labels along with the same file,
just save a project. But you can also export the labels to a simple
text file, and import them. This allows you to save information about
the locations of events in an audio file for use in another program,
and also provides a way to mass-edit the labels if necessary.
To export a Label Track, choose Export Labels... from the
File Menu. The exported file will
contain one line per label, starting with the time offset in
seconds, then a tab, and then the name of the label, for example:
1.217995 Bass intro 3.921073 Guitar enters 7.584454 Drums enter 11.070002 Chorus
To import a Label Track, choose Import Labels... from the
