The Timeline gives you a visual representation of a multitrack project, showing the position of clips, the playhead, and other items in time. You can add and arrange audio clips in the audio tracks, use sends to create auxiliary busses, and route audio to physical output channels using submixes. You can control the sound of each audio track, bus, and submix using the controls in its header.

Overview of Timeline Controls

The Timeline is organized into three groups of horizontal rows called tracks, busses, and submixes, as well as a video track, a podcast track, and a Master bus.

  • Previous and Next Selection buttons: Move backward and forward through Timeslice selections you’ve made in the waveform display.
  • Timeline editing tools: Select items using the Selection (arrow) tool, make time-based selections with the Timeslice tool, split audio clips using the Blade and Blade All tools, copy and paste attributes with the Lift and Stamp tools, and scrub the Timeline with the Scrub tool. For more information, see Using the Timeline Editing Tools.
  • Project controls: Set the project’s sample rate and other properties using these controls.
  • Global Timeline view: Shows a miniature view of the entire Timeline and the playhead position, and lets you move quickly to different parts of a project.
  • Time display: Shows the current playhead position in both Time-based and Beats-based formats. You can set the playhead by typing a new playhead position in the time display.
  • Time ruler: You can precisely position clips, the playhead, and other items to a specific point in time (minutes, seconds, frames) or to a musical beat using the Time ruler.
  • Track area: Includes horizontal rows for tracks, busses, and submixes. Also includes the playhead, envelopes, and markers.
  • Headers: Each track, bus, and submix has a header with an icon, name, volume slider, and other controls. (For more information, see Headers.)
  • Additional Timeline controls: Include controls to show the master envelopes, turn snapping on or off, set the track height, and zoom in or out. For more information, see Additional Timeline Controls.
  • Scroll bar: Moves the Timeline horizontally so you can see different parts of the project.
Additional Timeline Controls

The lower-left corner of the project pane contains controls for various aspects of Timeline display and operation.

  • Snapping button: Turns snapping on or off. For information about snapping, see Using Snapping.
  • Height control: Sets the height of tracks, busses, and submixes to one of four settings, from Reduced to Large. In the File Editor project view, sets the height of the envelopes for the current audio file project to one of four settings, from Reduced to Large. For more information, see Setting Track Height.
  • Zoom control: Click the control or drag the slider to change the zoom level. You can zoom in to edit clips precisely, or zoom out to display more of the Timeline. For more information, see Using the Zoom Control.

Each track, bus, and submix in the Timeline has a header that includes the track name, track icon, and a set of track controls. For detailed information on using the track controls, see About the Track Controls.

Figure. Elements of the track header.
  • Color label: Indicates the track color, which is applied to any clips on the track (unless you choose to override the color for individual clips).
  • Icon: You can choose an icon for the track, bus, or submix, making it easy to quickly distinguish it in a large project.
  • Name field: You can type a new name for the track, bus, or submix in the name field. You cannot rename the Master bus.
  • Bypass Effects button: Select this button to hear the track without any of the applied realtime effects.
  • Arm for Recording button: Enables (or disables) the track for recording when you click the Record button. Only tracks have Arm for Recording buttons, not busses or submixes.
  • Mute button: Mutes (or unmutes) the track, bus, or submix.
  • Solo button: Solos (or unsolos) the track, bus, or submix. Soundtrack Pro supports both multiple solo and exclusive solo.
  • Envelopes disclosure triangle: Shows the track, bus, or submix envelopes in the area directly below the track.
  • Volume slider: Sets the track, bus, or submix relative volume in the overall mix.
  • Input Routing buttons: Use the Input Routing buttons to confirm or change recording input signal routing.

    Note: This is visible only when the track height is set to Medium or Large.

  • Panner: Sets the pan position of the track or bus. Has two modes: stereo slider or surround panner. Appears in track and bus headers only, not in submix headers or the Master bus header.
