How to Use Audio Annotation

The audio annotation tool allows you to add annotations to time intervals in an audio file. Use the draggable markers at the bottom of the audio player (see Figure 5) to select the time interval. The audio tool will also provide suggestions for contextual semantic tags as you type your annotation.
