The overview contains the signal of the whole audio set (sound file or sequence). The overview graph can contain the waveform or only the time-scale. This region can be enabled/disabled. The overview plot contains two cursors which can be used for segmentation or to select the signal for playback or for viewing in the segment lines region. The overview line optionally contains segment markers. Warning: For large sound files with many segments, the time for segment marker display/update can be very long, and using the Transcription Script may be advisable.
