Here is an overview of the main elements of the Overtone Analyzer user interface:
Timeline
The Timeline shows an overview of the entire recording or loaded audio file as a waveform.
Current Range Slider
This determines the time range that you see in the Analyzer View. You can click and drag the Current Range Slider with the mouse, and you can resize its left and right borders to change the current range.
Time Cursor
This shows the current point in time when recording sound or playing it back. During playback, you can simply click into the Timeline or Analyzer View to jump to that position instantly.
Piano Keyboard
This is a playable piano keyboard. You click on individual tones, or use Ctrl-Click to select entire accords and play them with the "Play selected tones" command.
Staff View
The Staff View shows a musical staff with all the notes in the current range. It also shows the current notes played on the piano. The colored areas in the background indicate the ambitus (the range from lowest to highest singable note) of the singing voices and of the singable overtones.
