Audacity is a free audio editing and recording program. It does not feature markers, but instead uses labels to mimic the function of markers. Markers distinguish between tracks of a recording. When an album is recorded through Audacity, it may appear as one long, continuous track. This occurs when there are no separations, or markers, between tracks. If users want to separate segments of this continuous track into smaller portions, perhaps to find their favorite part of the track later, they can use Audacity's label function.
Install Audacity on your computer. If you have not done so already, the software can be downloaded for free (http://audacity.sourceforge.net/). If Audacity is already installed, open the software and load the sound file to which you want to add markers.
Insert your labels. Audacity does not use markers, but it does include a label feature that serves the same function. The sound file you loaded will appear as a long, single track. Click a segment of the track with your cursor where you wish to insert a label, which, like a marker, segments the track.
Press Ctrl+B to insert a label. Alternatively, you can select the "Project" tab in the menu list and then select "Add Label at Selection." The Label Track window should automatically appear and have created a label at the point in the track that you selected.
Add additional labels to your track. Continue to label all the segments that you want. Save your track into a file format of your choice, such as WAV, AIFF, or MP3 by selecting "File" and "Export Multiple." Type a name for your recording, a location to store the file and press "Export."
The "Label Track" window allows you to add whatever names you desire in order to remind yourself of the purpose for each label.
