Waveform Zooming

Zooming the waveform lets you work with precision. Zoom in to place loop markers exactly on a beat, or zoom out to see the full track structure at once. The waveform scrolls behind the fixed-centre playhead at all zoom levels.

Axis Determination

When you begin a two-finger pinch, NoteHound waits until the initial movement exceeds 12 pt before locking to an axis. Once locked, the gesture stays on that axis for its duration.

Horizontal Zoom (Timeline)

Pinch horizontally on the waveform to zoom the timeline:

Spread fingers apart — zooms in, expanding the waveform so individual beats and notes are visible
Squeeze fingers together — zooms out, showing more of the track at once
Range: 1x (full song) to 500x

Horizontal zoom is useful for setting precise loop start and end points. See Creating Loops.

Vertical Zoom (Amplitude)

Pinch vertically on the waveform to zoom the amplitude:

Spread fingers up and down — amplifies the waveform display, making quiet passages more visible
Squeeze fingers together — reduces the amplitude display
Range: 0.25x to 8x

Vertical zoom does not affect audio volume — it only changes how the waveform is drawn. It’s useful for finding quiet passages that are hard to see at default zoom.

Auto-Normalize

Toggle auto-normalize (vertical zoom button in the Waveform Toolbar) to have NoteHound automatically scale the waveform height to fill the available display. This is useful when the recording level varies significantly across the track.

Resetting Zoom

Triple-tap anywhere on the waveform to reset both horizontal and vertical zoom to their defaults simultaneously. The three taps must occur within a 400 ms window.

Tip: After zooming in to set a loop point, triple-tap to return to an overview before scrubbing to a new section. This saves time compared to manually pinching back out.
