Segments and Gaps

Cubase automatically analyzes the audio and splits it into segments that are shown in the waveform image.

To understand and edit the segmentation, the following concepts are crucial:

  1. Pitch position

    The pitch position of the segments is indicated by the piano keyboard to the left of the waveform. Pitches represent the perceived fundamental frequency of the sound. The average pitch of a segment is calculated from its micro-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 multi-channel file.

  4. 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.

  5. 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.


    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. Otherwise, later pitch modifications affect only the tonal portions.

  6. Micro-pitch curves

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