Oscilloscope is a precise audio-analysis display in the Core Analytics category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.

Open Oscilloscope

Launch the visualizer with its matching left-nav entry selected.

Quick start

  1. Start the demo track, choose a local audio file, or enable a live input.
  2. Try a preset or style first, then open the section for the part of the image you want to change.
  3. Open the settings sections and adjust the controls that shape this visualizer's built-in response.
  4. Use Reset to Defaults whenever you want to return to the original look.

Audio modulation

This visualizer uses its Audio or sensitivity controls for its built-in response. Its settings do not currently show Assign modulation on individual sliders.

Show AxesOn / OffShows time in milliseconds and spectrum frequency in Hz with a fixed dB scale.
Align Zero CrossingOn / OffAligns the short trace to a rising zero crossing when available.
SignalMono (Mixed), Left, RightDisplays the mixed signal or one audio channel.
Window1ms–20msUses the available samples; axes show the actual duration at your sample rate.
Tuning20Hz–2000HzSets the polar rotation frequency manually; does not detect pitch.
Delay0.05ms–10msSets the time separation between the two delay-view coordinates.

Vertical Scale0.25x–4xSets the visual vertical scale.
Dc Offset-1–1Shifts the whole trace up or down on screen without changing its shape.
Horizontal Offset-1–1Slides the trace left or right across the screen; negative values move it left and positive values move it right.

Tips for a better audio visualization

  • Use a little smoothing for readable movement, then lower it when you want fast percussion to register sharply.
  • Set the overall sensitivity first, then adjust color and motion separately so louder sections remain readable.
