Waveform Toolbar
Waveform Toolbar
A row of small buttons below the waveform provides controls for sections, zoom, the timeline ruler, and more. Each button toggles a feature on or off.

Buttons
| Button | Icon | Description |
|---|---|---|
| Eye | eye / eye.slash | Toggle section overlays on/off. Only visible when sections exist. |
| Vertical Zoom | up/down arrows | Toggle waveform amplitude auto-fit. When active, the waveform scales to fill the available height. |
| Offset Mode | left/right arrows with line | Toggle audio offset adjustment mode. When active, dragging the waveform adjusts the MIDI-to-audio offset instead of scrubbing. See Navigation — Offset Mode. |
| Timeline Ruler | timer | Show or hide the time ruler along the bottom edge of the waveform. The ruler occupies 16 pt and uses an adaptive time format. See Timeline Ruler below. |
| Overview Bar | split rectangle | Toggle the overview bar visibility. Filled icon when visible, outline when hidden. See Overview Bar. |
| Section Lock | lock / lock.open | Lock sections so they cannot be accidentally moved, resized, or deleted. Orange when locked. Only visible when sections exist. Pro only. |
| Import Sections | download-on-square | Import section markers from the audio file metadata. If sections already exist, a confirmation dialog asks whether to overwrite. Pro only. |
| SEC+ / SEC x | text | Toggle section creation mode. When active (white text on orange background), drag on the section strip area to define a new section. Only visible when sections are not locked. Pro only. |
Timeline Ruler
The timeline ruler displays time markers along the bottom edge of the waveform to help you read exact positions. Toggle it with the timer icon in the toolbar.
Height: 16 pt at the bottom of the waveform area.
Time format adapts automatically to the zoom level:
| Zoom level | Format | Example |
|---|---|---|
| Zoomed out (tick interval >= 1 s) | M:SS | 1:30, 0:45 |
| Medium zoom (0.1 s — 1 s) | M:SS.d | 1:30.5 |
| Zoomed in (tick interval < 0.1 s) | M:SS.fff | 1:30.500 |
Ticks: Major ticks have a 5 pt line and a time label. Four minor ticks appear between each major tick with shorter 2.5 pt lines. Tick spacing adapts automatically (target: ~80 pt between major ticks), snapping to “nice” intervals: 0.01 s, 0.025 s, 0.05 s, 0.1 s, 0.25 s, 0.5 s, 1 s, 2 s, 5 s, 10 s, 15 s, 30 s, 60 s, 120 s, 300 s.
