Transport Controls

Transport Controls

The transport bar provides quick access to playback, navigation, and loop markers. All buttons are designed for one-handed use.

Transport bar

Buttons (Left to Right)

  • Go to Start (skip-to-beginning icon) — jumps the playhead to 0:00, or to the A marker if looping is active.
  • Skip Back 5s (rewind-5 icon) — rewinds the playhead by 5 seconds.
  • Set A Marker (green “A” badge) — places the loop start marker at the current playhead position.
  • Play / Pause (large orange circle) — toggles playback. Shows a play icon when stopped, pause icon when playing.
  • Set B Marker (red “B” badge) — places the loop end marker at the current playhead position.
  • Skip Forward 5s (forward-5 icon) — advances the playhead by 5 seconds.
  • Go to End (skip-to-end icon) — jumps the playhead to the end of the audio file, or to the B marker if looping is active.
  • Loop Toggle (repeat icon) — enables or disables looping between the A and B markers. Highlighted in orange when active.

Time Display

The current playback time is shown on the left in M:SS.d format (minutes, seconds, tenths). The remaining time is displayed on the right with a minus sign (e.g., -1:15.7).

How to Set an A-B Loop

  1. Play or scrub to where you want the loop to start.
  2. Tap the A button.
  3. Play or scrub to where you want the loop to end.
  4. Tap the B button.
  5. Tap the Loop Toggle to enable looping.

Playback now repeats between the A and B markers. You can refine positions by dragging the markers on the waveform.

Scrubbing

You can move to any point in the track directly from the waveform:

  • Single-finger drag on the waveform scrolls the audio past the playhead
  • Release with momentum — the waveform continues scrolling and gradually slows to a stop, similar to scrolling a list

Scrubbing works whether audio is playing or paused.

Tip: You can set markers while audio is playing — no need to pause first. This makes it easy to mark loop boundaries on the fly.

Tip: For precise positioning, zoom into the waveform first using a horizontal pinch, then drag slowly. See Waveform Navigation for more detail.
