Annotations Example

Create and edit annotations on the audio timeline. Add regions with text labels to mark important sections, segments, or timestamps.

Adding New Annotations

Click the "+ Add Annotation" button or press the A key to create a new annotation at the current playhead position.

Default duration: New annotations are 3 seconds long by default
Smart sizing: If another annotation is nearby, the new annotation will shrink to fit the available space
Minimum size: Annotations require at least 0.5 seconds of space
Smart placement: If the playhead is inside an existing annotation, the new annotation will be created at the next available gap

Once created, you can resize annotations by dragging their edges, or use the keyboard shortcuts to fine-tune the boundaries.

Key	Action
`A`	Add new annotation at playhead or next available gap
`↑` / `←`	Select previous annotation
`↓` / `→`	Select next annotation
`Home` (Fn+←)	Select first annotation
`End` (Fn+→)	Select last annotation
`Escape`	Deselect annotation
`Enter`	Play selected annotation
`[`	Move selected annotation start earlier
`]`	Move selected annotation start later
`Shift + [`	Move selected annotation end earlier
`Shift + ]`	Move selected annotation end later

Editable mode: Toggle to enable/disable annotation editing
Link endpoints: When enabled, moving one annotation's edge automatically adjusts the adjacent annotation
Continuous play: Automatically advance to the next annotation during playback
