Noise Level: a loader for voice input

Noise rings whose wobble follows a level prop. A React visualizer for voice and audio input in AI voice interfaces. Install with shadcn.

Installation

Install with the shadcn CLI, or copy the component file. It only needs React.

npx shadcn@latest add https://oxyn.space/r/noise-level.json

Updates live with the parameters you set.

import { NoiseLevel } from "@/components/noise-level";

export function Thinking() {
  return (
    <NoiseLevel />
  );
}

Prop	Type	Default	Description
level	number	0.5	How strong the wobble is (0–1). Feed it a live microphone or audio level; it glides, so raw readings are fine.
lines	number	4	Number of concentric rings.
lineSpacing	number	3	Gap between neighboring rings in px. Keep it low so the rings sit close together.
lineWidth	number	1	Stroke width of each ring in px.
amplitude	number	8	Strength of the noise: how far the outer ring is pushed in or out, in px. Inner rings move proportionally less.
frequency	number	0.8	How many bumps run around a ring. Low values give broad, soft swells; high values give tighter ripples.
speed	number	0.7	How fast the noise drifts over time.
spread	number	0.12	How differently neighboring rings move. 0 keeps them in lockstep; higher lets each ring wander on its own.
size	number	160	Width and height of the orb in px.
minOpacity	number	0.35	Opacity of the innermost ring. The outer ring is always fully opaque.
color	string	"#e4e4e7"	Line color.
paused	boolean	false	Coast to a stop on the current frame without unmounting. Turning it off eases back up to speed.
label	string	"Thinking"	Accessible name; the wrapper is role="status".
className / style	—	—	Spread onto the wrapper div, along with any other div props.

Noise Level is one of the animations in Noise Rings. Use the group when the agent's state changes, and it morphs between them.
