With Livescribe Desktop, you can play an audio recording while viewing its linked pages Single-Page View. You can also play an audio recording by itself in Audio View.
If you play back an audio recording that spans multiple pages, Livescribe Desktop automatically moves to successive pages in real time synchronization with the playing audio. This automatic paging continues until you manually switch pages using Paging Controls. From then on, the paging is under manual control only until play back another audio recording.
This starts the audio playback. This is analogous to tapping your notes in a notebook to play back the audio recording. Playing an audio recording also opens the Sessions tab in the Navigation Pane.
When
you mouse over ink that is active, the mouse cursor changes to a
pointing hand cursor 
to help you identify where
you can click to begin audio playback.
If you added notes while playing back an audio recording, Livescribe Desktop shows this ink as blue, by default. You can click on this ink to play back the audio at the point where you added the notes.
You can change the color of active and inactive ink by setting a preference.
