The Advanced Player uses standard audio playback, rewind, and repeat control buttons. The Master volume is controlled with a slider control.

The user can enlarge the audio track display, make the display smaller, or reset the size to full screen. This enables the user to navigate between tracks and move their relative positions when they are replaying multiple call recordings.

To mute an individual call, click the call’s speaker icon. To adjust the volume up or down, use the call’s volume slider. Click Isolate to hear only that call recording.

Use the Call Selection controls to identify a section of recordings. Use the red cursor line to select the Start (|<) and End (>|) points. If the user clicks Selection, only the selection between these points plays. Click on X to clear the selection area.
