Segments and Gaps

The following concepts are crucial to understand the segmentation:

1. Pitch Position

   The pitch position of the segments is displayed on the piano keyboard to the left of the waveform. If you move the mouse pointer over a segment, the pitch of that segment is also shown on the segment. Pitches represent the perceived fundamental frequency of the note. The average pitch of a segment is calculated from its pitch curve.

2. Time Position

   The time position and the length of the segments are indicated by the timeline.

3. Audio Waveform

   The audio waveform is always shown as mono, even if you have opened a stereo or multichannel file.

4. Gap

   The gaps in between segments represent the non-tonal portions of the analyzed audio. These can be caused by breath sounds or rests, for example.

   Note

   Gaps, caused by weak audio signals or audio sections with unclear pitch information, such as consonants or effect sounds, must be included in the segments manually. To do this, you must change the start and end points of a segment. Otherwise, later pitch modifications affect only the tonal portions.

5. Segment

   The segments represent the tonal portions of the analyzed audio. The pitch and time position of the segments allow you to associate the segments to the original audio.

6. Pitch Curve

   The pitch curves that are shown in the segments represent the progression of the pitch.
