HLS can import Audacity labels to help automate precise beat track creation.
First, make sure you have installed the Queen Mary Vamp plugins: http://vamp-plugins.org/download.html

====Creating a Label Track in Audacity:====
----
[[File:ArchivedChristmasWiki_HLS_Audacity_Beat-tracker.PNG|350px|thumb|Figure 10.5-1]]
* Open Audacity and open your mp3 file.
* Click ''Analyze -> Bar and Beat Tracker: Beats...''
* The window shown in Figure 10.5-1 will appear. Select the beats per bar. This will place the specified number of labels for each measure of music. For example, if you choose 4, and there are 4 beats per measure in the song, you will have one label for each quarter note. Setting this to 8 would give you one beat for each eighth note, etc.
*(Audacity will now analyze the file to determine the beats.)

*Once complete, you will see the label track that has been created.
*Click ''File -> Export Labels''.
*Save the resulting text file.
*'''Tip:''' Create a "Label Tracks" sub-folder in the HLS main folder for saving these files.

====Adding the Labels to HLS====
----
[[File:ArchivedChristmasWiki_HLS_Add-word-channel.PNG|200px|thumb|Figure 10.5-2]]
*Open HLS and either open the sequence that uses that audio, or create a new sequence using that audio.
*Open Channel Manager (''Manage Channels -> Manage Raw Channels'').
*Click ''Add Control Channel''. Figure 10.5-2 will appear.
*Select "Word" and click OK.
*Scroll to the word channel and name it something meaningful (such as Audacity). Click ''Done with Changes''.
*Add the Audacity channel to a display group and make that display group active.
*Right-click on the first cell in the word channel and select ''Add Audacity Label Track File''.
*Labels will be added similar to those seen in Figure 10.5-3.
*'''Tip:''' Add the channel to the beat channel group or make it sticky so you can use it as reference.
