Here is how each term is to be understood.
A segment is a portion of an audio waveform that is defined by segment boundaries.
Segment boundaries can be added with the auto segmenter (), in some cases. Alternatively, you can add them manually. You can click and drag a boundary to move it.
Each segment has a start time and an end time which is determined by the locations of its boundaries in the waveform.
The start-end times of a segment can appear in discussions.
You can transcribe segments separately from one longer audio file. The loop control () helps you do this. See Also: Mark Verses.
A region is a portion of an audio waveform that you selected manually with your mouse.
Each region has a start time and an end time which is determined by the portion of the waveform you selected.
The start-end times of the selected region can appear in discussions.
If you edit an audio waveform you can select a region and use (Delete Region) to delete that portion of the waveform.
