Three steps to a video.
A beam, not a line
Trails fade behind the beam as it moves, focus controls how tight or blown-out it looks, and glow adds the halo around it. Turn the trails up and fast passages smear the way a real scope does.
Fourteen looks
Feed it your stereo track for a true X-Y scope, or draw classic figures: Lissajous, rose, spirograph, harmonograph, torus, knot, and more. Or upload your own image and have the scope trace that.
The whole screen, not just the line
Scanlines, curved glass, and darkened edges, each adjustable. Plus a warp control that lets your audio rough up the clean shapes, so they pick up the grit of a real scope instead of looking computer-perfect.
What makes a scope look like a scope
A green line on black is a screenshot of an oscilloscope. The beam is what makes it an oscilloscope.
The bit most tools skip
Plenty of visualisers offer an "oscilloscope" that is a thin line drawn on a dark background. It reads as a waveform display, but it does not read as hardware, and it is hard to say why until you see them side by side.
The difference is the beam. A real scope draws with a glowing point moving across the screen, and almost everything characteristic about the look comes from how that behaves, not from the shape of the line itself.
What the beam actually does
Four things, all of which are adjustable here:
- Persistence. The screen keeps glowing after the beam has moved on, so fast passages leave fading trails rather than a clean line.
- Focus. The beam has thickness, and it glows brighter where it slows down or doubles back on itself.
- The screen itself. Scanlines, the curve of the glass, and the darkening around the edges.
- Grit. A real trace is never perfectly clean, which is what the warp control brings back to the generated shapes.
X-Y mode and why it matters
The other thing a real scope does is X-Y mode: instead of drawing the sound over time, it plays the left and right channels against each other. Stereo content becomes a shape, and a fully mono signal collapses to a diagonal line.
That is the mode oscilloscope music is written for, where the audio is engineered so the X-Y plot draws a recognisable figure. You do not need specially engineered audio to use it, though. Feed it a normal stereo mix and the width of your track becomes the shape, which for most producers is a more interesting readout than a scrolling waveform.
