Waveform Navigation
Waveform Navigation
The waveform display is the primary way to move through a track. NoteHound’s waveform is designed for precise, comfortable navigation — whether you’re jumping to a section or inching through a single beat.

The Playhead
The orange playhead is fixed at the horizontal centre of the screen. The waveform scrolls behind it as audio plays. Small arrow indicators at the top and bottom mark the exact position. This design keeps your position always visible and makes scrubbing feel natural.
Scrubbing
To move to a different position:
- Single-finger drag left or right on the waveform
- The waveform scrolls under the fixed playhead in real time
- Scrubbing works during playback and while paused
Momentum Scrolling
When you release a drag with some velocity, the waveform continues scrolling and gradually decelerates — similar to a list view. This makes it easy to scan through long tracks quickly.
- Drag velocity is estimated from the last 80 ms of movement
- Momentum decays adaptively based on the current zoom level
- Tap once anywhere on the waveform to stop momentum scrolling immediately
Marker Dragging
Touch and drag an A or B loop marker directly on the waveform to reposition it.
- Each marker has a 20 pt hit radius for easy grabbing
- While dragging, a coloured guide line appears — green for A, red for B (3 px, 90 % opacity) — showing the exact position
- If both markers fall within the hit radius, the closest one is selected
- Markers cannot be dragged when locked (see Waveform Toolbar)
Offset Mode
Toggle offset mode from the Waveform Toolbar (left/right arrows with line icon). When active, dragging the waveform adjusts the MIDI-to-audio sync offset instead of scrubbing.
- Double-tap while in offset mode to clear the audio offset
- A small label such as “+0.12 s” or “-0.05 s” appears centred at the top of the waveform in orange monospaced text
What You See on the Waveform
- Playhead — orange line at centre with arrow indicators
- Loop region — blue-tinted overlay (12 % opacity) between the A and B markers. The green line marks loop start; the red line marks loop end. See Creating Loops.
- Section overlays — coloured labels at the top of the waveform showing song structure. See Creating Sections.
- Overview bar — a miniature view of the full track at the bottom. See Overview Bar.
- Audio offset label — shown when offset is active (see above)
Tip: Zoom in before scrubbing for bar-level precision. A horizontal pinch makes individual beats clearly visible. See Waveform Zooming.
